Heuchera Richardsoni.
Reading edition
Richardson's Heuchera; Nat. Ord. Saxifragaceæ.
A taller variety than H. Drummondi. The most striking distinctions are the pale green colour of the young leaves contrasting with the bronzed appearance of the older ones, and the larger size of its flowers, which, however, are green.
Cultivation and flowering period, as for other species.
