About Epilobium glaberrimum Barbey
Epilobium glaberrimum, a species of willowherb, has the common name glaucous willowherb. This clumping perennial wildflower is native to western North America, ranging from central Canada to northern Mexico. It typically grows at moderate elevations in moist habitats. The plant shows some variation in physical appearance. It can grow taller than half a meter, and produces hairless foliage with leaves that measure between 1 and 8 centimeters in length. Each flower has four notched petals, which can be purple, pink, or white; individual petals range from only a couple of millimeters to over one centimeter long. The fruit is a narrow, stick-shaped capsule that grows 2 to 7 centimeters long. Two valid subspecies are currently recognized: Epilobium glaberrimum ssp. fastigiatum (Nutt.) Hoch & P.H.Raven, and Epilobium glaberrimum ssp. glaberrimum.
