Heuchera americana

Coral Bells is an excellent foliage plant with deep-green leaves turning to purple, red, and yellow in the fall. Clusters of tiny, greenish-white, delicate flowers on slender stalks rising above the leaves bloom in late spring to early summer. Use it as an edging plant, or plant in masses as a groundcover. Good choice for shade gardens.

Hemerocallis spp.

Daylily is an easy-care perennial with attractive, arching, blade-like leaves. Varieties are available in a wide range of flower colors, mainly shades of yellow, orange, and red. Its large, lily-shaped flowers bloom continuously from midsummer to fall. Use in the perennial flower border, massed in beds, or as a groundcover.

Heliopsis helianthoides

Smooth Oxeye’s daisy-like, yellow-orange flowers with darker centers bloom from midsummer to fall. The bright, showy flowers are excellent fresh-cut. Deadheading the spent flowers will prolong blooming. Smooth Oxeye grows naturally along stream banks and woodland edges. Use it in beds, borders, and wildflower gardens.

Helianthus annuus

Common Sunflower has large flower heads with dark centers and bright yellow rays. The flower heads, which turn to face the sun, bloom on tall, hairy stems July-August. Birds love to feast on the seeds, and the nectar is a valuable food source for native bees. Use the taller varieties, which may need staking, in the back of borders, and dwarf varieties in beds or the front of borders.

Helianthemum canadense

Frostweed’s yellow flowers bloom May-June at the top of the stems and only open in sunlight. This plant does well in sandy or dry, rocky soil. It is best suited for naturalizing rather than formal landscapes. As temperatures drop in late fall, sap from the stems of this plant form ice crystals, inspiring its common name. Use in sunny areas of woodland gardens or for naturalizing. Frostweed may be difficult to find commercially. Tell your local garden center or nursery about your interest in this plant.

Helianthus angustifolius

Swamp Sunflowers have yellow rays and reddish-brown to purple centers; they bloom September-November. Pinch the growth in early June for bushier plants with more blooms in the fall. This plant tolerates wet areas of the yard and bog-like conditions, and is suitable for rain gardens or the edges of water features. Use as a specimen plant or massed in beds.

Helenium autumnale

Common Sneezeweed has daisy-like flowers with distinctive, fan-shaped rays and prominent, raised centers. The flowers bloom from late summer until frost in colors ranging from yellow to reddish-brown to orange. The tall plants add vertical texture to gardens, but may need to be staked. Pinch back plants in early June for bushier growth with more blooms. The common name is based on the former use of its dried leaves to make snuff, which was inhaled to cause sneezing. Sneezeweed has special value for native bees. Use Sneezeweed in the back of borders or beds, wildflower gardens, and naturalized areas.

Hamamelis virginiana

The floral display of American Witchhazel is unique. Its fragrant, cream to yellow flowers with tassle-like, crumpled petals bloom September-December, persisting for some time after leaf drop.

Halesia tetraptera

Carolina Silverbell is a large shrub or medium tree with a rounded crown. Drooping clusters of showy, white, bell-shaped flowers bloom in early spring. The flowers are followed by four-winged fruits, which turn tan in the fall. This plant prefers moist, well-drained, organic soils, and grows well with Rhododendrons and Azaleas. Use it in the shrub border or woodland garden, as an accent tree near decks or patios, or as a specimen tree for the lawn.

Gleditsia triacanthos var. inermis

Thornless Honeylocust is a large, fast-growing, urban-tolerant deciduous tree. Its small leaflets and open crown cast a light shade that permits shade-tolerant grasses and perennials to grow underneath, making it a good choice for filtered shade. The seed pods are a food source for birds and other wildlife. Protect the bark of young trees, since white-tailed deer and rabbits may eat the soft bark in winter. Use Thornless Honeylocust as a street tree, on slopes for erosion control, or for windbreaks.
