Ilex glabra

Inkberry is an evergreen holly with spineless leaves. Tiny, greenish-white flowers bloom in the spring, followed by black berry-like fruits in late fall and winter. The flowers are a source of nectar for bees, producing the flavorful Gallberry honey.

Ilex cornuta

Chinese Holly is a dense, rounded evergreen shrub. Its small, white, fragrant flowers bloom in May. Since it is dioecious (separate male and female plants), a male must be in the area to pollinate the female flowers for fruit production. Plant in a location protected from cold winter winds. Use Chinese Holly as a specimen or foundation plant, or plant in groups for a hedge or privacy screen.

Hyssopus officinalis

Hyssop is a shrubby, semi-evergreen perennial with fragrant leaves. Fragrant, blue-violet flowers bloom June-September. Use as an ornamental or herb garden plant.

Hydrangea anomala ssp. Petiolaris

Climbing Hydrangea is a woody deciduous vine with root-like holdfasts for climbing. White, fragrant flowers in clusters blooming late June to early July are good for cutting and drying. Attractive exfoliating (peeling), reddish-brown bark of the mature vine provides winter interest. Use it as a flowering cover or screen on brick walls, arbors, and trees. It can be slow to develop at first, but will grow quickly once the roots are established.

Helianthus divaricatus

Woodland Sunflower’s bright yellow flowers with darker yellow centers bloom July-September; the showy flowers are good fresh-cut. This wildlife-friendly plant provides nectar and pollen for native butterflies and bees, and seeds for a variety of birds. Use it in shady borders, cutting gardens, or for naturalizing. It will spread over time by rhizomes (underground stems).

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.

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.

Gymnocladus dioicus

Kentucky Coffeetree is a deciduous tree that has large, compound leaves and brown bark with distinctive scale-like ridges. It is dioecious (separate male and female trees), with greenish-white flowers blooming in the late spring. The female trees bear reddish-brown seed pods that persist into winter. Use Kentucky Coffeetree in large yards or parks. Its tolerance for drought and air pollution makes it a good urban tree.
