Anemone hybrida (x) JAPANESE ANEMONE Sound perennials with colonizing roots that grow best in an open position in deeply dug, heavy, moist and fertile loam soil. They provide a durable display of both flower and foliage. Long and free blooming with leaves that are dark green, lobed, pointed and vinelike. Anemone tomentosa 'Robustissima' flowers earlier than the other Japanese Anemones. It is an extremely vigorous grower and useful where such a plant is desirable. Its leaves are gray green beneath. A. sylvestris prefers a more humusy soil, colonizing in open woodlands. Anemone canadensis has clear white single flowers held high above the foliage, and is a very strong growing plant that needs room to move.

Angelica gigas GIANT WILD PARSNIP Large plant with huge leaves that have a tropical appearance. Striking flower clusters resembling giant alliums are produced. A short-lived perennial or hardy biennial (3 - 4 yr.), but produces ample seed. Likes deep fertile soil that is moist, not very dry or wet. Useful for architectural variation, a lush impression in the garden, and also for a daring central subject for bouquets. Towering in full bloom, the gardener stands eye to eye with Angelica. Angelica pachycarpa Extremely glossy green leaves command attention. Prefers moist but well drained soil.

Anthemis tinctoria ‘Charme’ GOLDEN MARGUERITE This perennial chamomile is handsome in both foliage and flower. Light green foliage arises from basal rosettes being finely cut and taking on the appearance of Achillea. Numerous golden daisy-like flowers are held above the foliage in summer. Autumn color is of the familiar shades orange to brown. Plants perform best in full sun, well-drained sites with moderate to poor soils, plants become lanky if soil is to rich. Cut plants back after flowering to encourage basal growth and rebloom.

Anthriscus sylvestris ‘Ravenswing’ A chocolate leaved biennial chervil. Clusters of tiny white flowers sparkle against the dark foliage in early summer. Perhaps better suited to a meadow than a tailored perennial border since plants do self-sow. Reseeding can be tamed by deadheading before seed dispersal. Not entirely picky when it comes to cultural requirements often found inhabiting wasteland, site plants in sun to part shade with well-drained soil.

Aquilega COLUMBINE Thrive in any normal garden soil that is preferably moist but not wet, and moderately sunny. Vigorous plants with elegant divided glaucous green foliage, and distinctively shaped flowers on wiry branching stems. Self sows. If grown in shade, bright shade produces better blooming. Mixed color cultivars contain a same color on a given plant. Hummingbirds are attracted to the nectar of the spurs. A. 'Biedermeier' NOSEGAY COLUMBINE Foliage distinctively more neatly compact. Overtopping the foliage are 1 1/2 in. flower clusters in a profuse "honeycomb" of upward facing, short-spurred blooms, more tightly distributed than the A. 'Blue Shades' and A. Mckana's larger, more gracefully nodding flowers. A. canadensis WILD COLUMBINE A graceful native with its own unique elegance. Its 1 1/2 in. long nodding flowers may be smaller than most cultivars and not for those who want "big". Yet some hold this one their favorite, considering the native columbine species more stately than the cultivars, with dark green foliage, and in this case less prone to leaf minor, as well as its tolerance of more moderate amounts of moisture and preference to a bit more shade. Though A. McKana Hybrids are quite popular, A. 'Music Mix' is similar, yet shorter. A. caerulea 'Rocky Mountain' bears large, long spurred, upright flowers.

Arisaema triphyllum JACK-IN-THE-PULPIT In woodland haunts of childhood, this flower and even its common name seem to stop time to allow quiet moments to look, almost without fail. Has two 3 - lobed leaves with a blue green underside and 1 ft. stems which grow taller after flowering. An often brightly colored leafy structure partly surrounds the spike and bends over it. Its inside is purple or bronze purple with lighter stripes. The inside fleshy spike is purple or greenish brown, or occasionally green. Red to orange red berries (if pollinated) are a food source for wildlife. Needs moisture retentive, fertile soil with plenty of humus in part shade to shade. Native woodland plant.

Artemisia WORMWOOD Tolerant to poor, infertile, dry soils. Reasonably drought tolerant once established. Artemisia ludoviciana 'Silver King' stands erect with excellent, wide deep silver foliage and can be invasive where it is happy. A. l. 'Valerie Finnis', a more restrained grower, has wide leaves with an eye catching glow to them. The shrub-like Artemisia 'Powis Castle' is one of the finest cultivars and combines well when paired with many other plants. Prune in spring or summer but not any later. In mid summer trim Artemisia schmidtiana 'Nana' ('Silver Mound') to promote fresh growth and shapely plants. Aromatic fine textured foliage is silvery green to gray white, forming a soft, tight mound that invites touch.

Asarum WILD GINGER This woodland ground cover spreads its heart shaped leaves easily, although at times slowly, in moist, slightly acidic, fertile soil with good drainage. A. canadense CANADIAN WILD GINGER produces 6 in. matte green, deciduous leaves covered with fine hairs. A. europaeum EUROPEAN WILD GINGER has 3 in., leathery, shiny, dark green leaves that persist in winter. The unusual flowers are hidden by the foliage. Asarum maxima PANDA ASARUM Suggested Zone 6 with protection. Just completing its’ third New York winter (2006), in a foundation planting here at the nursery. Leaves dark green, glossy with silvery grey mottling. A true garden gem, the contrast of pure white and velvet black flowers are stunning.

Aster ASTER Valuable plants that are lavish bloomers for summer and fall gardens. Grow well in reasonably moist, fertile soil. Wet soil in winter can be detrimental. Leaves are undivided, narrow, linear and sometimes toothed. Plant kinds range from under 12 in. to well over 4 ft. tall. Whacking tall types in early summer will produce a more compact plant, although flowering will be delayed a bit.
