Description

Sidalcea malviflora is somewhat variable in appearance and there are many subspecies. In general it is a perennial herb growing from a woody caudex and rhizome, its stem reaching about 60 centimeters in maximum height. It is sparsely to densely hairy in texture. The leaf blades are variable in shape, but are often divided deeply into several lobes. The inflorescence is a dense or loose array of several flowers. The flower has five petals in shades of bright to dark pink, often with white veining, and measuring one to over three centimeters in length.
