Bransford, W.D. and Dolphia
Epilobium obcordatum Gray
Rockfringe
Onagraceae (Evening-Primrose Family)
USDA Symbol: EPOB
USDA Native Status: Native to U.S.
A low, clumped, mat-forming perennial with 2-6 in. creeping stems. A matted plant with a short creeping stem and, in upper leaf axils, deep pink flowers seemingly too large for plant and often hiding foliage. These stems, with willow-like leaves, are smothered with showy, four-petaled, rose-purple flowers from mid- to late-summer.
Most Epilobium species are tall, but this, like many other alpine plants, is low and compact, which protects it from the drying mountain winds and freezing temperatures.
