HABITAT & HARDINESS: Heuchera americana is native from Ontario south to Georgia and west from Nebraska to Louisiana. For the most part, plants are indigenous to rocky open woods, crevices or ledges of basic rock outcrops and calcareous woodlands. Plants are hardy from USDA Zones 4-8.

Do heucheras like sun or shade?

They do well in all well-drained soils, from chalk to clay. Most prefer semi-shade. As a rule of thumb the darker coloured Heucheras withstand full sun better than the lighter coloured ones. They will tolerate dry soils but only when established - normally six months after planting.

Are all Heuchera native to North America?
