Heuchera - Coralbells

Most Heuchera listed below are hardy zones 3 to 9 in partial shade on average to fertile, moist, well-drained soils. They attract hummingbirds and are deer resistant.
Heuchera is sometimes prone to Black Vine Weevil which feeds on the plants roots and the crown, otherwise they are rarely bothered by pests or disease. Heucheras are moderately salt tolerant and also very tolerant of Juglone released from the roots of Black Walnut trees. Foliage nematodes may occur but are rare. It is recommended to mulch these shallow rooted, woody based plants during winter to prevent frost heaving.

Heuchera americana ( American Alumroot )
A clump forming perennial native to dry woods in eastern North America ( from eastern Nebraska to southern Michigan to southern Ontario to Connecticut; south to eastern Oklahoma to central Georgia ). It is endangered in Ontario where all known remaining populations are from Essex County though it originally occurred further east to Norfolk County. It is also endangered in Wisconsin, New York State, Delaware and Mississippi. In the Windsor/Essex County, Ontario region; it was locally abundant in Lasalle, around Amherstburg and on the Lake Erie islands during the 1800s. It also occurred abundantly on the Ohio shore and sporadically at Detroit during that time.
It forms a clump of lobed, toothed, leathery foliage, up to 10 inches high. The leaves, up to 4 inches wide, are mottled with purple-brown at first, turning to glossy green. The foliage remains evergreen in mild areas.
The greenish-white flowers are held just above the leaves in early summer.
A woodland plant that tolerates hot humid summers as long as it is not exposed to hot afternoon sun. Hardy zone 4 to 8 preferring full shade to partial shade but tolerating some sun. Pruning is usually limited to removing old leaves during late winter to make room for the fresh new foliage.

  4. Your plant's are looking very beautiful and thanks for sharing a very useful and informative blog with us. I really don't have any idea about Heucheras. After seeing you post I think I should also add Heucheras plant in my yard. Surely they will give an extra ordinary look to my garden when I'll add Hostas and Heucheras in garden.
