Rockfringe (Epilobium obcordatum) is showy with it's 4" pink flowers clustering around the base of granite boulders or peeking out of the fissured cliff faces. This is a two inch tall creeping plant of the sub-alpine and alpine fellfields. The small glabrous gray leaves are rounded and held close to the stems giving the nonflowering plants a neat tidy appearance. Once in bloom one hardly notices the foliage since the flowers steal all the attention.
It can be seen growing in the Cascade, Sierra Nevada, Steens, Strawberry and Sawtooth Mountain Ranges of north central CA, north eastern NV, south eastern OR and central ID.
