We believe we grow one of the most unique selections of plants available in the state. We attribute this to our passion, perspective, influences, and the fact we grow and seek much of our own and select many of our own named cultivars. Perhaps our plant selection may be as easily identified by what we don’t grow, a portion of which are such popular plants most nurseries would consider it economically untenable not to carry. It may be our loss, but we rest assured these plants will be found elsewhere so the customer will not be let down. For now, we stick true to our personal tastes. We believe less is more, and the number of plants we grow reflects this as we have a comparatively small inventory of just over 200 varieties. Each and every plant we carry is heavily scrutinized for its usefulness in creating a naturalistic garden. Our inventory varies from year to year based on our success in overwintering, propagation, sales, and any new additions or omissions. We carry one-gallon pots for retail sales of all our perennials. Almost all our plants are hardy to at least zone 5. For anyone building a garden from scratch or in the field of garden design, thus looking for a larger quantity of one type of plant, there is the option to buy trays of 15- pint-size pots at a more economical price. This option varies from plant to plant and season to season. Some plants are unavailable this way.
Potting soil is made on-site and all plants are potted anew each spring. Due to the nature of our operation, we are particularly susceptible to variations in weather from year to year and strive to have most of our plants available by June 1. Some of these will have had plenty of time to root, others not. Flowering tends to be seasonally correct (not forced) and our sales area provides a seasonal cross-section of flowering succession month by month as occurs here in the state of Maine. We recommend buying plants which have not been shipped from hothouses from the south, (and which are over-fertilized, possibly sprayed with pesticides, etc.) but from local sources who maintain their own stock. Locally grown plants are more likely to survive our local climate and the growing practices can be personally consulted. Our stock is not organic due to our minimum use of a slow-release pelletized fertilizer, yet we do not use any pesticides whatsoever. Furthermore, our lack of shipping and ubiquitous hothouses (one small) keeps our carbon footprint very low. Please recycle any (and only) pots you may have purchased from us for reuse by the nursery. We try to remain as sustainable as an operation as possible.
Invasive vs. Strong-growing
We do not carry any plants known to be invasive in the state of Maine. However, we do suggest you pay close attention to the behavior of a plant, particularly prolifically self-sowing plants, to determine your level of comfort with this often useful and sometimes discouraging characteristic. Read the plant descriptions thoroughly in order to educate yourself concerning growth habit and means of reproduction.
Often the term “invasive” is misused for ‘strong-growing’, which many of our plants are. This is their nature, yet they are determinate in growth and will stop once reaching a particular size. Our biggest concern (aside from true invasives) are plants which once established, cannot be completely removed (without the use of herbicides), and regenerate from small pieces of remaining root – indefinitely (think Bishop’s weed or comfrey). Strong-growing plants are often the lowest maintenance if their growth habit is anticipated and they are used in conjunction with other strong-growers. This is one of a few prerequisites in creating a low-maintenance garden (see resource: lists- “Robust and long-lived perennials useful for less-intensively maintained gardens”). Solidago and Asclepias are strong-growing native genera which, given the right species, will dominate a garden in an ‘invasive manner’, yet are known to be very beneficial to wildlife – and are beautiful. They do not seem to mind whether a plant is native or not as they potentially displace it through their on-going growth. Gardeners must decide for themselves if this growth habit is acceptable given their objectives and the size of the planting area, i.e. willing to have a less-diverse planting in order to accommodate particular choice plants.
The North American (Northeast) Aesthetic
Over the years European botanists and horticulturalists have crossed the Atlantic Ocean in search of useful ornamental plants from North America, particularly those from various grassland habitats of the mid-west. This effort has led to many new hybrids and cultivars being developed in Europe from our own native stock. Beginning late in the 20th century the New Perennial Movement in Europe, led by Dutch plantsman Piet Oudolf, brought to the forefront of contemporary garden/landscape design many northeast natives and mid-west prairie plants (forbs and grasses) which we have come to love: Echinacea, Monarda, Aster, Solidago, Eupatorium, Asclepias, and grasses such as Andropogon, Sporobolus, and Panicum, to name a few. Many of these plants owe their claim to fame not only because of their showy and abundant flowers at a time when many European wildflowers are past their height but also for their long-lasting structure which persists well into winter in skeletal form. Many of these plants are also very low-maintenance (thus energy-efficient) (see resources: lists – “Plants with long-lasting seed-heads and/or winter skeleton”). New hybrids and cultivars of North American genera continue to be introduced to the trade on an annual basis. One result of all this is a simultaneous popularity surge in plants which are aesthetically superior and fitting for a naturalistic planting and plants which are wildlife-friendly and well-adapted to the state of Maine. We can have a beautiful, low-maintenance, wildlife-friendly garden year-round here in New England due to these developments and our wonderfully useful indigenous flora.
Native vs. Non-native . . . Species, Hybrid, Cultivar
At present our plant selection is roughly half North American and half Eurasian in origin. Because we are very interested in the aesthetic and artistic prerequisite of a plant many non-natives remain part of our selection even though some have little benefit to native insect herbivores. Many do provide food in the form of seed and nectar, however (see resources: lists – “Nectar”). Our selection is leaning more and more strongly toward North American plants every year but will always contain some of both. We believe the inspiration and pleasure found in gardening with novel plants from foreign climes remains a legitimate source of creativity and necessary addition to making visually stimulating landscapes. But as is becoming more apparent, a balance must be found. This is particularly true for ever-expanding urban and suburban areas lacking in diverse natural habitats and which are therefore less capable of supporting native insects and the food web which rests upon them. Aesthetically speaking, North American genera by in large have some of the most striking and long-lasting forms. Both the Highline in New York City and Lurie Garden in Chicago provide excellent examples of large-scale public landscapes with a majority of natives combined with a minority non-natives (see resources: links – “Naturalistic Public Gardens”). Many natives (considering the whole flora of a region), though beneficial to wildlife, are not ornamental enough to incorporate into highly-visible ornamental landscapes, particularly public ones. Furthermore, many are very aggressive growing/self-sowing and are not compatible with low-maintenance and diverse planting. What the public generally refers to and admires in a native flora is something akin to a charismatic mega-flora and unknowingly omit the overwhelming majority of less aesthetically pleasing plants which are native. In our opinion, the ideal plant is an ultimately useful plant – ornamental throughout the seasons (dynamic) and edible (part of the local food-web).
Native species plants are the best for supporting wildlife largely because they support native herbivorous insects, the unsuspected top herbivore (not deer or woodchucks) of our local ecological habitats. The focus tends to be on nectar as the greatest attribute of native plants, which is certainly important, though non-natives can provide nectar just as well. Asclepias syrica, one of our native milkweeds, is not only important to Monarch butterflies due to its nectar but even more so because it is the only genus that provides forage for the Monarch butterfly larvae. This is an important aspect of insect-plant relationships: host-plant and larvae have co-evolved and many like the Monarch are specialists. With this in mind, one must understand that to learn to love supporting our native wildlife means learning to love feeding herbivorous insects (and thus carnivorous insects, songbirds, etc.). In order to feed our native herbivorous insects, we must learn to embrace, or at least tolerate, another aspect of ecological, natural, or naturalistic plantings – bug-eaten foliage. Luckily these planting styles are the most accommodating to this occurrence.
Aside from the importance of plant-larvae relationships, we must also bear in mind that spiders play an equally important role as a source of bird food. As carnivores spiders are less particular about which plants they use to ambush their prey, though some are clearly specialists in their use of camouflage. As a result, spiders seem to be much more abundant in an herbaceous planting of garden type than are insect larvae. Below the ground, we must consider a whole other realm of organisms. The vast majority of animal life in a garden is contained in the soil, most of which are decomposers such as invertebrate grazers, fungi, bacteria, and the invertebrate predators who feed upon them. All of these creatures rely upon the continual input of decaying organic matter in the form of dead plant material. Thus, we allow the old growth of plants to decay in place where it is readily used by these various creatures. It is true, a messy garden is more conducive to animal life than a tidy one. Vertebrates such as snakes and rodents also rely upon the spacial complexity of a “messy” garden in order to find a suitable and safe niche to hide.
Hybrid plants are crosses between two different species of a genera. These crossings most often result in a variety of spectacular flower colors (think Echinacea and Achillea) but usually the form remains much the same. This is an example of how form is the ‘soul’ of a plant, and perhaps why structure should be the focus of design in our gardens (see resources: lists and terms – “Plants with a long season of interest”). Many hybrids are sterile – they do not produce nectar, pollen, or seed. They are dead to pollinators and seed-eating birds (and seed-savers). We try to limit our use of these plants, though they remain the plant industry’s number one money-maker and have thus made it illegal to propagate such plants (without permission) for further sale based on ownership of plant patents. Cultivars are “named” wild species plants that are grown in cultivation. Individual wild plants are selected for outstanding naturally occurring characteristics and are maintained through vegetative propagation (cloning) in order to remain true to type. Cultivars are another major source of new commercial introductions. Yet cultivars are capable of producing nectar, pollen, and seed, and seedlings will often resort to the species phenotype (common physical appearance) if allowed to self-sow. Some cultivars come true to type from seed. We focus largely on both species plants and cultivars because of these factors and because they tend to be the most natural-looking, thus most fitting for our design work.
Nursery Catalog 2019
Herbaceous perennials are the ideal artistic plant-medium for use in naturalistic planting design. They are quick to mature, diverse and dynamic in character, and most importantly, easy to move around and arrange as one inevitably does to fine-tune a design idea. Here we present what we consider an exceptional selection for use here in Maine.
Key – LIGHT: Su (Sun), HSh (Half-shade), Sh (Shade-tolerant)
ACHILLEA, Asteraceae, yarrow
An important genus for the garden, especially because of the unusual inflorescence, a flat pancake-like flower- head whose form is indispensable among the numerous spike and cluster-shaped inflorescence in the garden. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton. Tolerant of dry low-fertility soils where they spread moderately. May fail to over-winter in poorly-drained soils.
filipendulina ‘Parker’s Variety’
3.5′ / deep yellow / June.-Sept. / Su
A cultivar of the species filipendulina, which is the only one that can truly be considered perennial. Remarkably long lasting structure for arid plantings. Native to the Caucasus Mountains in southeastern Europe.
ACTAEA, Ranunculaceae, baneberry
Indispensable plants for shady spots. Foliage is composite pinnate or bipinnate, and flowers are small white or yellowish on elongated spikes. In the wild these plants grow in damp woods or ravines where the sun seldom shines. In gardens they can tolerate a good deal of sun provided the soil does not dry out. Slowly-spreading. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton. A robust and long-lived perennial useful for less intensively maintained gardens.
6′ / white / July-Aug. / HSh-Sh
A large plant with long, slender white flower spikes on long stems rising above clumps of green finely-cut foliage. Native to eastern North America.
6.5′ / white / Sept.-Oct. / HSh-Sh
A giant plant with dark green foliage tinted purple and elongated flower candles. The white flowers have purple-red calyxes and flower stems. A very strong plant which never collapses. The red of the foliage intensifies in full sunlight. More drought tolerant than other selections. Species native to Russia, China, Korea and Japan.
simplex ‘James Compton’
3′ / white / Sept-Oct. / HSh-Sh
A vigorous, earlier flowering, compact cultivar with bronze-black foliage and creamy-white flower candles.
AGASTACHE, Lamiaceae, giant hyssop
Wonderful garden plants with extremely strong stems and young foliage covered in a purple haze and smelling of licorice. The plants produce flowers over a long period and are frequented by bees and butterflies. Slate gray Juncos, sparrows and finches peck at the seeds throughout the fall and winter. Species plants are often short-lived, so they should be given an opportunity to self-seed. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton.
3′ / blue / July-Sept. / Su
A hybrid of A. rugosa and A. feoniculum, with shiny foliage and dark spikes covered with true blue flowers. Sterile so not self-seeding, but lasts longer.
ALLIUM, Liliaceae, onion
Ornamental onions, with their more or less spherical inflorescence covered in small flowers, have become very popular in recent years, as this architectural form is unique and indispensable. Allium is the largest genus of all bulbous plants containing hundreds of species including such edibles as onion, leek, garlic, and chives. A fewer number of species create moderately spreading clumps and thus are more useful when used in naturalistic plantings. As well, unlike bulbous alliums, these species keep their attractive grass-like leaves all season and can thus be used more extensively. A robust and long-lived perennial useful for less intensively maintained gardens.
angulosum ‘Summer Beauty’
2′ / pink / July-Sept. / Su
An older, popular cultivar with a pink spherical inflorescence and bright-green strap-like foliage. Adored by pollinators. Distinctive and long-lasting seedheads and/or winter skeleton. A robust and long-lived perennial useful for less intensively maintained gardens. The species is native to a wide region of central Europe and northern Asia.
18″ / light-purple / April-May / Su
Commonly called chives, this bulbous perennial which is often used for culinary purposes is also a useful ornamental. Forms clumps of long, narrow, dark-green grass-like foliage from which arise spherical, clover-like clusters of soft-purple flowers. Well adapted to arid conditions where it will self-sow. Only allium native to both new and old worlds, occurring across much of Europe, Asia, and North America.
AMORPHA, Leguminosae, lead plant
3′ / purple / June-Aug. / Su
Leadplant is a small deciduous, bushy shrub in the pea family, native to well-drained soils of the North American prairie. It has small purple flowers grouped in finger-like racemes and protruding from each flower are bright orange-tipped stamens. Very beautiful small-leafed, pinnate, soft-haired foliage gives it a leaden hue and its common name. Its roots can reach 4 feet deep making it drought tolerant. Particularly attractive when grown within low-growing grasses, much like it is found in the wild. Non-spreading. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton. Slow to establish.
AMSONIA, Apocynaceae, bluestar
Virtually ideal, long-lived, slowly spreading garden plants with narrow, hairless leaves, racemes of pale blue star-like flowers, and a tidy shrub-like form. Very good structure from spring to late winter with long-lasting seed heads and/or winter skeleton. A robust and long-lived perennial useful for less intensively maintained gardens. Limited self-sowing.
2.5′ / steel-blue / June-July / Su-HSh
The decorative value of this plant is mainly due to the needle-shaped leaves which turn a wonderful shade of orange and yellow in autumn. The small racemes of steel-blue flowers in early summer are an added attraction. Native to the Ouachita Mountains in central Arkansas.
2.5′ / steel-blue / June-July / Su-HSh
A strong and slow-growing but extremely long-lasting plant which eventually forms solid clumps with elongated willowy leaves. Bears striking racemes of steel-blue star-shaped flowers followed by attractive oblong seedpods. Beautiful autumn coloring is also part of the bargain. ‘Galaxy’ is a Campo di Fiori selection that is particularly striking with its large, deep-blue buds and broad foliage which remains fresh-green into deep fall. Native to Missouri.
ANAPHALIS, Asteraceae, pearly everlasting
2′ / white / Aug.-Sept. / Su-HSh
Pearly everlasting is the one species native to North America. Attractive woolly dark gray-green lanceolate foliage and small papery white flowers born in flat heads. At home in humus-rich woodland soil in half-shade, though found growing in arid railway embankments and amongst grass in beach dunes. Very good structure from spring to late winter with distinctive and long-lasting seedheads and/or winter skeleton. Limited spread. A local selection. This plant provides food for the larvae of the American Painted Lady butterfly, which is often seen in the nursery browsing on the foliage.
ANEMONE, Rununculaceae, windflower
This anemone from China and Japan flowers last, grows tallest, and is moderately spreading. They have large deeply-cut foliage and airy racemes of relatively large delicate flowers on long stems. Must be protected during the first winter. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton. A robust long-lived perennial useful for less intensively maintained gardens.
5′ / pale pink / Aug.-Sept. / Su-HSh
A tall growing cultivar which bears pale pink flowers. Can become rampant on fertile soil.
2.5′ / carmine-pink / Sept.-Oct. / Su-HSh
A strong-growing hybrid with deep carmine-pink, semi-double flowers produced over a long period.
ARALIA, Araliaceae, spikenard
5′ / cream / June-July / Su-HSh
The smallest species in the genus from eastern North America. Bears compound leaves and panicles of cream-colored, fluffy, ivy-like flowers followed by shiny black berries. Although it grows best in semi-shade and fertile, moisture-retentive soil, it is remarkably strong and can tolerate poor soil, sun, and drought. It has a limited spread in light shade. Robust and long-lived perennial useful for less intensively maintained gardens.
ARUNCUS, Rosaceae, goat’s beard
Indestructible plants that will grow almost anywhere provided they are given time to acclimatize. Their foliage is typical of the rose family, composite and divided, with an inflorescence of cream-colored flowers in elegant plumes. Non-spreading showy plants for the woodland border. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton. A robust and long-lived perennial useful for less intensively maintained gardens.
5′ / cream / June-Aug. / Su-HSh
A very tough plant with attractive divided foliage and large plumes of long-lasting cream-colored flowers. Seedhead is insubstantial. Useful in dry shade. Native to North America.
4′ / cream / June-July / Su-HSh
A breathtakingly beautiful cross between A. dioicus and A. aethusifolius. Bears elegant panicles of small cream-colored flowers on reddish-brown stems. Very good structure from spring to late winter with distinctive long-lasting seedheads and/or winter skeleton.
ASURUM, Aristolochiaceae, ginger
8″ / brown / Mar.-April / HSh-Sh
Moderately spreading plants for deep shade and good woodland soil that does not dry out. Bears kidney-shaped, dark, glossy evergreen leaves with light green veins. The curious three-petal purple-brown flowers remain concealed under the leaves. Ideal groundcover in a woodland setting provided the soil does not dry out. Prefers calcareous soil but tolerant of acidity. More ornamental than our native species. Native to large parts of temperate Europe.
ASCLEPIAS, Asclepiadaceae, milkweed
Plants of North American origin with fleshy lance-like foliage and unique sweet-smelling flowers in loose umbels which develop into large pointed seed pods. More importantly, they are the sole food source for Monarch butterfly larvae. New growth emerges late in spring. All species are native to eastern North America.
4.5′ / pale pink / July / Su
A sturdy border plant with umbel-shaped inflorescence covered in sweet-smelling pale pink flowers which are dark red in bud. The flowers attract many insects and are followed by attractive upright, pointed seedpods. A non-spreading, relatively short-lived perennial with a longevity of 5 years or less.
incarnata ‘Ice Ballet’
4.5′ / cream / July / Su
A unique white-flowering form of the above species. Comes true from seed
3′ / orange / June-Aug. / Su
Bushy clumps with umbels of bright orange to yellow-orange flowers atop upright to reclining hairy stems, with narrow lance-shaped leaves. Tolerant of dry infertile soils and somewhat slow to establish with a limited spread. This sub-species is also very tolerant of heavier clay soils. It does not transplant well due to its deep taproot, so best left alone. Unlike other milkweeds, this specie’s stems do not exude a milky sap when broken.
speciosa – coming soon
ASTER, Asteraceae, aster
Many aster species have been ignored over time, some of which are very beautiful. Their charming simplicity and abundance of flowers late in the gardening season have brought them into the spotlight once again. Asters are strong plants which thrive almost anywhere. Some varieties must be divided every 3-4 years in spring otherwise the clumps will become too big and the outside flower stalks will collapse. The low-growing bushy varieties do not have this problem. The New England asters can be a bit floppy and are best grown amongst plants of similar height for support. Fairly recently the genus has been taxonomically reorganized following recent DNA-based evidence. We are sticking to the old names for now as the new ones are not yet familiar to the public (or us). As New Englanders, we are charmed to live in a landscape that is host to a plethora and diversity of asters that adorn our landscape for months in the fall. All of these asters are native to the northeast except where noted.
2′ / white / Sept.-Oct. / Su-Sh
A compact aster with narrow heather-like foliage and arching inflorescence covered in delicate, tiny, white yellow centered flowers. Unique habit. Thrives in a sunny dry location where it spreads moderately. A robust and long-lived perennial useful for less intensively maintained gardens. A local selection.
2′ / white / Sept.-Oct. / Su-HSh
A bushy cultivar with very dark, small, purple-black foliage and an abundance of tiny free-flowering little white blooms with reddish centers. The foliage color ensures the plant is always attractive even when not in flower. Slowly-spreading and self-sowing. A Campo di Fiori selection.
2′ / grey-blue / Sept.-Oct. / HSh-Sh
A particularly tough species with grey-blue flowers and course green foliage. Large silvery bracts remain ornamental through the winter. Useful in dry shade as a slowly-spreading ground cover via rhizomes. A local selection.
novae-angliae ‘Alma Potschke’
4′ / deep bright-pink / Sept.-Oct. / Su
A shorter cultivar of the infamous New England aster with intense bright pink flowers on sturdy stems. Slowly-spreading. A robust and long-lived perennial useful for less intensively maintained gardens.
5′ / bright-pink / Sept.-Oct. / Su
A tall bushy selection with beautiful bright-pink flowers and contrasting bright yellow centers. Slowly-spreading and self-sowing. A robust and long-lived perennial useful for less intensively maintained gardens. A Campo di Fiori selection.
5′ / deep-purple / Sept.-Oct. / Su
A dificult to find cultivar of New England aster with deep-purple flowers. Slowly spreading. A robust and long-lived perennial useful for less intensively maintained gardens.
novae-angliae ‘Honey Song’
3′ / light-pink / Sept.-Oct. / Su
A shorter cultivar with light-pink flowers. Slowly spreading. A robust and long-lived perennial useful for less intensively maintained gardens.
6′ / white / Sept.-Oct. / Su
A tall growing plant with inflorescence of creamy white flowers grouped into large flat umbels held on dark red stems. An important plant for the back of the border whose beautiful silhouette persists through the winter. This extremely strong moderately-spreading plant will thrive anywhere. One of the first native asters to bloom. Self-sows. A robust and long-lived perennial useful for less intensively maintained gardens. A local selection.
oblongifolius ‘October Skies’
1-2′ / violet-blue / Aug.-Sept. / Su
Aromatic aster is a bushy, stiff, low-growing plant with hairy stems, small-leaved aromatic foliage, and clouds of medium-small violet-blue flowers. Tolerant of many soil types but particularly happy in arid conditions. Native northeastern and central U.S.
cordifolius ‘Little Carlow’
2.5′ / soft-blue / Sept.-Oct. / Su-HSh
A hybrid between two native asters, A. cordifolius and A. novi-belgii, and which is very popular in European gardens but difficult to find here in the U.S. A vigorous mound-forming plant covered in medium sized sky-blue flowers. May need support in fertile, moist soils.
1.5′ / violet-blue / Sept.-Oct. / HSh-Sh
Stiff aster, our most diminutive native aster, occurs locally in dry, sandy, open settings where it forms neat mounds of rough needle-like foliage topped by pretty violet-blue flowers. Native to eastern North America. A local selection.
3′ / deep lavender-blue/ Aug.-Sept. / Su-HSh
A tough hybrid with striking deep lavender-blue flowers above relatively broad foliage. Very useful in the shade, even in dry conditions.
ASTILBE, Saxifragaceae, false goats beard
Plants with beautiful pinnate leaves and panicles of flowers that look a little like spirea. They have a shallow root system and the slightest lack of water will make their leaves curl up and turn brown. Numerous cultivars have been introduced, yet we have chosen a few with particularly long-lasting architectural qualities and color shades which can be readily incorporated into a naturalistic planting. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton. A robust and long-lived perennial useful for less intensively maintained gardens. Species native to China.
tequetii ‘Visions in Pink’
2.5′ / soft pink / July-Aug. / Su-HSh
A recent introduction with compact soft pink plumes.

A recent introduction with compact dark purple-red plumes.
3 / bright purple-pink / July-Aug. / Su-HSh
A stiff, upright plant with a long, lightly branched inflorescence. Spreads well but is not rampant. Species native to China.
ASTRANTIA, Apiaceae, masterwort
Unique old fashioned plants that are back in fashion. Attractive glossy and shallowly indented foliage. The flowers are subtly colored bracts (called involucres with umbels) within which the true umbel-shaped flower can be seen. All like cool, fertile, moisture-retentive soil, and performance is strongly dependent on habitat. Slow to moderately-spreading. Some cultivars are prolifically self-sowing. A relatively short-lived perennial with a longevity of less than 10 years. Native to central and eastern Europe.
major ‘Abbey Road’
2′ / dark purple-pink / June-Sept. / Su-HSh
A recent introduction with dark purple-pink flowers on dark stems.
2′ / antique-rose / June-Sept. / Su-HSh
A particularly vigorous and long-blooming hybrid with antique-rose colored flowers.
2.5′ / cream / June-Sept. / Su-HSh
A cultivar with large cream-colored flowers with large green bracts. Vigorous.
BAPTISIA, Fabaceae, false indigo
Wonderful plants whose popularity has risen dramatically with the recent native plant movement, and which has resulted in numerous cultivars in far-ranging colors. They look a little like lupins (they are related) but have far more verve. These slowly spreading plants reach a ripe old age but take some time to become established. They turn a contrasting black in autumn. Deeply-rooted and drought tolerant. Very good structure from spring to late winter with long-lasting seed heads and/or winter skeleton. A robust and long-lived perennial useful for less intensively maintained gardens.
3.5′ / indigo blue / June / Su
The strong steams bear bluish-green leaves and truly indigo blue flowers. These are followed by fat gray-green pods which turn black in winter. The most cultivated species. Native to much of North America.
australis ‘Lemon Meringue’
4′ / soft yellow / May-June / Su
A hybrid between B. sphaerocarpa and B. australis with soft yellow flowers and stems covered in a smoky haze of anthracite.
4′ / cream / May-June / Su
Tallest of the baptisias with a unique statuesque tree-like habit. Adorned with cream-colored lupin-like flowers in tall and sturdy racemes reaching well above a mound of trifoliate bluish-green leaves. Purple black stems and buds are covered in a whitish bloom. Native to mid-west North America.
sphaerocarpa ‘Screamin’ Yellow’
3′ / bright yellow / May / Su
A cultivar noted for its profuse bloom of bright yellow pea-like flowers in erect racemes that rise well above a mound of bright green trifoliate leaves. Rounded seed pods turn tan-brown when ripe. Native to south-central U.S.
CALAMINTHA, Lamiaceae, calamint
A genus of aromatic garden plants closely related to thyme and mint. The most important feature is the long flower stems on which an airy inflorescence is formed. Tolerant of dry low-fertility soils. Limited spread and moderately self-sowing. Very good structure from spring to late winter with distinctive and long-lasting seed heads and/or winter skeleton.
subsp. nepeta ‘White Cloud’
1′ / pure white / July-Oct. / Su
A white flowered cultivar of the species, similar to Blue Cloud, yet shorter.
CAMASSIA, Hyacinthaceae, camas
Beautiful bulbs which produce spires of star-like flowers. Suited to naturalizing in moisture-retentive soils where they spread slowly. Dig the plants every four years to separate the bulbs. This will ensure better flower production. Like daffodils, the foliage becomes untidy after flowering, so best situated behind a taller-growing, later-flowering plant. Attractive seedheads add early summer interest. Native to moist mountain meadows from British Columbia to Southern California. Roots used as a food source by many native peoples of these regions.
3′ / deep blue / May-June / Su
A cultivar with hefty spires of deep blue.
CEPHALARIA, Dipsacaceae, giant scabious
8″ / lemon yellow / June-July / Su-HSh
A huge plant with a subtle lightly branched inflorescence full of lemon yellow scabiosa-like flowers above large coarsely indented foliage. Because of its airy appearance, it is also suitable for planting between medium-tall plants. The plants do not collapse when grown in soil that is not very wet. Moderately self-sowing and non-spreading. A relatively short-lived perennial with a longevity of less than 10 years. Native to the Caucasus.
CLEMATIS, Ranunculaceae, old man’s beard
There are a few perennial Clematis species that never or rarely become woody and which emerge from the soil every spring. However, like the majority of species, they must be provided support, ideally by surrounding shrubs or sturdy perennials. Rich soil is appreciated. Non-spreading. A robust and long-lived perennial useful for less intensively maintained gardens.
6.5 / ceram-colored / June-Aug. / Su-HSh
A cultivar with deeply cut, purple-tinged foliage and stems, and clouds of fragrant, cream-colored flowers followed by decorative seed tails.
COREOPSIS, Asteraceae, tickseed
8′ / yellow / Sept.-Oct. / Su-HSh
An attractive tall species of tickseed suitable for the back of the border. Slender stems with rosettes of narrow, elegantly divided foliage and racemes of small yellow flowers with brown centers. Long stems appreciate support from plants of similar size. Slowly-spreading. Native to North America.
2′ / cream-yellow / June-Aug. / Su
This cultivar of thread-leaf coreopsis is a strong growing rhizomatous perennial which grows in dense bushy clumps, and whose daisy-like creamy yellow flowers appear in dense clusters from late spring to late summer. Beautiful filigreed foliage. Moderately spreading. Tolerant of drought and low fertility. A robust and long-lived perennial useful for less intensively maintained gardens. Species native to eastern US.
DALEA, Fabaceae, prairie clover
2′ / purple-red / July-Aug. / Su-HSh
A compact, seed-grown cultivar with fine clover-like leaves and cone-shaped spikes on which, from bottom to top, whorls of purple-red flowers keep on appearing. A robust and long-lived perennial useful for less intensively maintained gardens. Native to central North America.
DIANTHUS, Caryophyllaceae, carnation
Many species belong in this genus of sun-and drought-loving plants with grass-like foliage. Most are plants for enthusiasts that require special care and attention. Here is a stronger wild species.

These wonderful plants which so frequently dominate open habitats around the world have been loosely regarded and little-noticed in the gardening world, until recently. Their increasing popularity is no mystery. Essential for creating a wild, naturalistic-looking planting, they project themselves uniquely in the way they catch the light, the way they move in a breeze, and the contrast and continuity they bring to a planting through the seasons with their long-lasting structural form. Textured mounds of linear green foliage, beautiful autumn coloring, and long-lasting seed heads extend the season of interest almost indefinitely. A must for every garden.
Cool-season grasses have their greatest impact in the garden in the spring and early summer when many of them flower. Although many of these grasses become dormant during a hot summer, some such as Calamagrostis and Deschampsia retain their dramatic, albeit dead, inflorescences and continue to play an important role in the garden for many months after. For this reason, the flowering season for both cool-season and warm-season grasses also includes the period of seed head interest.
Warm-season grasses do not start growing until much later in the year, typically flowering in late summer and often retaining their dead foliage and seed heads into the winter to great effect. The largest and most impressive ornamental grasses are of this group.

Foliage turns deep orange in autumn fading to copper through the winter. Slow to establish in cooler climates. Deeply-rooted, drought tolerant, and long-lived. Moderately self-sowing. Native to North American prairies.
3′ / tan / July-Aug. / Su
A taller cultivar selected for reliable flowering in Europe and early flowering in north America.
viridula – coming soon
Much the same way grasses dominate open sunny habitats, ferns dominate the shady woodland floor (along with species of carex). Here in Maine, one must simply take a walk in the woods to discover the possibilities in garden creating. For like grasses, ferns are much less developed in terms of breeding and selection, even though they are the oldest plants on earth. Both grasses and ferns radiate a simple structural beauty which we ask much less of than the average wildflower, whose ephemeral flowers are forced to perform perfectly and luxuriously through continuous breeding. Because the beauty of grasses and ferns is inherent in their long-lasting foliage and form, there is little we need to do to improve upon them. Here we offer a small selection of a few of the best found growing in Maine for creating a naturalistic garden.
DENNSTAEDTIA, Dennstaedtiaceae, hay-scented fern
2 / – / – / HSh-Sh
The perfect ground-covering fern for those looking to establish a very low-maintenance planting in shady medium-moist conditions. Hay-scented fern is colony-forming producing a sea of single, yellow-green, triangular, upright, lacy fronds whose repetition entrances the eye, and is accentuated by emerging trunks of trees. Smells of hay when crushed. Rich coppery-orange fall color. Strong-growing and most suitable for larger plantings. A local selection.
OSMUNDA, Osmundaceae, royal fern
3-6 / – / – / HSh-Sh
One of the most architecturally striking native ferns with bold divided foliage, an upright stature, and tassel-like spore clusters at the tips of the fronds that turn brown as they ripen. Prefers moist to wet soils and will tolerate full sun given consistent moisture. Beautiful autumn coloring. Clump-forming. A robust and long-lived perennial useful for less intensively maintained gardens. A local selection.
POLYSTICHUM, Dryopteradaceae, christmas fern
2 / – / – / HSh-Sh
An evergreen fern which forms medium-sized fountain-like clumps of dark green, large-toothed, lance-shaped, leathery leaves. Dry-medium moisture in well-drained soils. A local selection.
NATIVE FRUITING SHRUBS:
We chose to grow these two selections specifically because they are diverse in their attributes, above and beyond other fruiting shrubs. Not the least is the strength in which each will naturalize in the landscape, given a variety of soil types, without a lot of coddling.
ARONIA, Rosaceae, chokeberry
6-8 x 5-8 / white / April / Su-HSh
Aronia has been deemed one of the new superfruits. Its myriad health benefits and culinary uses have led to a surge in commercial orchard production, in which Galicjanka has been widely planted due to its uniform fruiting habit. In spring clusters of white flowers are followed by black blueberry-sized fruit which adorns this small rounded shrub come late July or early August. The berries are very ornamental, contrasting with the electric-red fall foliage come autumn, until birds have eaten every last one. Aronia is a very adaptable plant that grows in almost any soil type, sun, or half-shade, forming small colonies through suckering growth. Useful as a screen or as a larger structural element in bigger naturalistic plantings. It begins to bear at 3 years. Free of diseases and insects. Native to the eastern U.S.
SAMBUCUS, Adoxaceae, elderberry
6-12 x 6-12 / white / June / Su-HSh
A vigorous multi-stemmed shrub whose large purple buds unfurl to produce wide cymes of little fragrant white flowers, providing an early source of nectar for native pollinators, and when dried, a fragrant medicinal tea. The highly nutritious and medicinal, small purple-black fruit hang in large clusters come late summer, for use in jelly, syrup, pie or wine, or as a treat for birds. Wyldewood is a consistently high-yielding cultivar that is well-adapted to a wide range of soil conditions. Useful in large naturalistic plantings with decorative berries and attractive compound foliage. Low-maintenance and easy growth. Native to the eastern U.S.
NATIVE NUT TREES:
Nuts as a food source are beginning to garner more attention not only because they are nutritious (a big part of the Mediterranean Diet), but also because they provide these foods by means of a long-lived perennial plant. Perennials have many advantages over annuals, one of which is their life-span, yet equally important, they require far less inputs to produce food. They are the backbone, nuts in particular, to the future of sustainable agriculture. These two selections, being native and reliable producers, are our focus. Both have the capacity to naturalize without a lot of coddling. For more information visit the Neohybrid Hazel webpage at our website.

Growing hazelnuts has been a special focus of ours for several years, one which we are now feeling confident enough to share. These are interspecific hybrids, which are open-pollinated, and whose characters will vary from plant to plant. In our breeding effort we have focused on saving seed from the very best, most productive parents. Hazels are poised to be a leader in sustainable food production as the plants are very long-lived and whose nuts are more flexible in their use then soy. Rounded vigorous bushes have showy male flowers, a long cylindrical catkin inflorescence which blooms just as the bees are waking up, but are instead assisted by the wind. The female flowers are minute buds in which only the small ruby-red stigmas are apparent, each stigma representing a nut. The nutritious nuts which are said to be 10,000 times more desirable to wildlife than acorns, appear in insignificant quantities as early as 3 years, with heavy production peaking around years 8-10. As production begins to drop, or the bushes become too difficult to manage, one may choose to coppice the whole of the plant in order to reinvigorate the plants productive potential. Coppiced wood may be used as trellising, ramial chips, biochar, or simply wood chip mulch. Most plants will begin to bear again in 2 years time, and a very few may not make the cut. Hazels are very adaptable to a wide range of climatic conditions and a diversity of applications, such as PYO, formal and informal hedges, and wildlife plantings. Beautiful fall foliage for the back of a large naturalistic planting. For more information visit our Neohybrid Hazelnut webpage.
Aside from our own insights and observations into the appearance, growth and use of the many plants we grow, with much appreciation, we have largely depended on many written and online resources to help us bring these things to light, in ways we ourselves have been unable. Furthermore, we recommend you explore these resources for more in-depth information.
