Bog willowherb
Family: Onagraceae · Type: perennial · Not Native
Bog willowherb is a naturalized perennial herb found in northern California Interior, Cascade Range, and central eastern Sierra Nevada regions in boggy meadows, seeps, and damp places at elevations of 800 to 1,630 meters. Flowering from June to September, this plant produces white or pink flowers 3.5 to 7 millimeters long with distinctive thread-like stolons tipped with fleshy bulblets. Growing with erect stems 10 to 100 centimeters tall that are densely strigose, it spreads through unique underground runners. Its leaves are linear to narrowly elliptic, approximately 20 to 75 millimeters long and nearly sessile along the stem. The slender fruit is gray-hairy and reaches 35 to 80 millimeters in length, with a persistent seed hair-tuft that aids in wind dispersal.
