Amelanchier laevis

Allegheny Serviceberry is a wildlife-friendly, large deciduous shrub. Drooping clusters of white flowers bloom before leaves appear, March-April. The flowers are followed by edible, berry-like fruits, which turn purple when ripe. The berries are often used in jams or baked goods. The flowers provide nectar for bees and have special value for native bees. The berries are consumed by a variety of birds and mammals. The leaves turn a beautiful orange-red in the fall. The ornamental bark of mature plants is smooth and gray with longitudinal stripes. This species is very similar to Common Serviceberry; it is distinguished by its smooth, not hairy, leaves and sweeter, juicier berries. Use Allegheny Serviceberry as a specimen, or plant it in masses in shrub borders, wildlife gardens, or along edges of water features.

Amelanchier canadensis

Canadian Serviceberry is a wildlife-friendly, large deciduous shrub. Drooping clusters of slightly fragrant, white flowers bloom before leaves appear, March-April. Its other common name, Shadblow Serviceberry, refers to the fact that the flowers bloom around the same time shad fish return upriver in early spring.

Amelanchier arborea

Amaranthus tricolor

Joseph’s Coat is a bushy annual grown for its vibrantly colored foliage. A variety of cultivars are available with leaves in shades of greens, yellows, reds, and browns. This plant is sometimes grown for culinary purposes, as the leaves are edible. The tiny, red-green flowers are inconspicuous. Tall plants may need to be staked. Use massed in beds and borders, or as an attractive accent along paths or edges.

Alnus serrulata

Hazel Alder is a fast-growing, deciduous shrub with a tendency to form thickets. It is monoecious (separate male and female flowers appear on the same plant). The greenish male catkins and reddish female catkins bloom March-April. The female catkins are followed by woody, cone-like structures containing the seeds; the “cones” turn a maroon color in fall and persist into winter. A variety of bird species eat the seeds. Fall foliage is yellow-orange. It prefers moist to wet soils, and is flood-tolerant. It grows naturally along stream banks and swampy areas. Alder is a nitrogen-fixing species, adding nutrients to the soil. For these reasons, Hazel Alder is planted as a pioneer species for revegetating disturbed areas along streams or ponds. It can also be used in mass plantings for erosion control or to restore wetlands.

Alnus incana

Gray Alder is a small, flood-tolerant, deciduous tree. It is monoecious (separate male and female flowers bloom on the same plant). Both flowers are purple-red catkins; the female flower is followed by a woody, cone-like structure containing the seeds. Birds, such as redpolls, siskins, chickadees, and goldfinches, feed on the seeds. This tree grows fast, but is short-lived, usually not lasting beyond 40 years. It prefers moist to wet soils and is flood-tolerant. Alder is a nitrogen-fixing species, adding nutrients to the soil. For these reasons, Gray Alder is planted as a pioneer species for revegetating disturbed areas along streams or ponds. It can also be massed for a windbreak or used for erosion control.

Allium schoenoprasum

Wild Chives is an edible perennial herb with attractive flowers. It is grown for its flavorful, onion-like leaves, which can be used in salads or cooked dishes.

Plants can be dug-up in the fall and grown indoors in a container window garden.

Ageratum houstonianum

Agastache foeniculum

Blue Giant Hyssop is a long-blooming, perennial herb known for its bright lavender-blue flowers and fragrant leaves. Spikes of the tubular, lavender-blue flowers bloom July-September; the flower spikes are good fresh-cut or dried for floral arrangements. The flowers are a good nectar source for bees, butterflies, and hummingbirds. Blue Giant Hyssop has special value to native bees and bumblebees. The leaves have a strong anise fragrance; they can be used to make herbal teas. Blue Giant Hyssop thrives in full sun and well-drained soil, and is drought-tolerant. It is a good choice for the dry, sandy soil conditions of seashore gardens. Use Blue Giant Hyssop in borders, herb gardens, or containers.

Aesculus flava

Yellow Buckeye is a large, deciduous tree. Erect clusters of yellow flowers bloom April-May. The round buckeye nuts turn brownish-red; the word “buckeye” comes from the light-colored scar on the nut, which gives the appearance of a deer’s eye. The nuts are a food source for wildlife. This tree has orange fall foliage. Yellow Buckeye needs moist, well-drained, fertile soil. Use it as a shade or specimen tree. Avoid planting it near patios, sidewalks, or driveways, since the fruits, leaves, and twigs may cause tree litter.
