Pioneer violet (Viola glabella), also known as Stream violet, is in the Violaceae family. Found in moist shady situations at low to mid elevations. Other native violets with a yellow bloom are either found in drier woods (V. nuttallii), in prairies with larger grayish leaves (V. praemorsa), at moderate elevations in the mountains (V. bakeri), have round leaves (V. orbiculata), have evergreen foliage (V. sempirvirens) or occur on the east side of the state. The above specimen was photographed at the Chehalis Surge Plain Natural Area Preserve, located outside of Aberdeen.
