Discussion

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.
