Heuchera Americana.
Reading edition
American Heuchera; Nat. Ord. Saxifragaceæ.
The flowers of this species are a dull or reddish purple. The foliage is rough and clammy; the form of leaf resembles that of H. glabra (see Fig. 51), but the colour is a lighter green. All the genus are of an astringent nature, but this species is remarkably so, and in its native country has earned for the family the name of "Alum-root."
For cultivation and flowering period see Heuchera.
