Discussion | Of conservation concern. Heuchera parishii occurs in the San Bernardino Mountains. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Heuchera chlorantha occurs in the Pacific Northwest north to the Queen Charlotte Islands of British Columbia. Inland, it occurs from the eastern base of the Cascade Mountains westward in Oregon and Washington. A putative hybrid between H. chlorantha and H. micrantha var. diversifolia, named H. ×easthamii Calder & Savile, has been reported in the Hazelton region of British Columbia. The leaf form and capsule size are intermediate between those of the two parents, both of which occur in the region. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
