Kalmiopsis leachiana

Kalmiopsis fragrans

Phenology Flowering late spring–early summer. Flowering early–late spring.
Habitat Open sunny ridges in xeric shrub community or sparse woodland, rooted in shallow or, more often, deeper soils, on a range of substrates, often including ultramafics Tuffaceous outcrops, within shaded, mesic, coniferous forests, open ridges, bare rock or shallow soil at bases of cliffs or boulders

Of conservation concern.

In cultivation, Kalmiopsis fragrans has sometimes been sold or labeled as the “LePiniec” form of Kalmiopsis. In the wild, it has a narrower geographic range (restricted to Douglas County in the southern Cascade Mountains of Oregon) and is significantly rarer than K. leachiana.
