Unless you’re a serious plant nerd, you’ve probably never heard of the plant genus, Urophysa. This small genus of only two species in the clematis family (Ranunculaceae) is only found growing in Karst cliff crevices in a few limited provinces of South Central China. In other words, they are quite rare. Urophysa henryi was originally named Isopyrum henryi, when it was thought to be a brother of our native Isopyrum biternatum. Urophysa is now considered most closely related to the famed half-columbine, Semiaquilegia adoxoides.
While the Chinese people mostly use Urophysa henryi as a medicinal treatment for bruises, etc., we prefer it as a winter-flowering gem in the rock garden. Here are our plants, which began flowering in our rock garden, just as we turned the page on the new year, 2022.
