Viola adunca (Hooked-spur violet)
Bransford, W.D. and Dolphia

Viola adunca

Viola adunca Sm.

Hooked-spur violet, Western Blue Violet, Western Dog Violet

Violaceae (Violet Family)

Synonym(s):

USDA Symbol: VIAD

USDA Native Status: L48 (N), AK (N), CAN (N)

A small plant with pansy-like bluish-violet flowers that hang at tips of slender stalks.

Violets are very popular wildflowers and garden plants, romantically described as shrinking because of the way the petals fold in. Species are often difficult to identify as they may hybridize, producing intermediate forms. These hybrids, in turn, may reproduce by means of inconspicuous flowers at the base of the plant, often even underground, producing seeds without opening.
