Oregon willowherb

Family: Onagraceae · Type: perennial · Native

Oregon willowherb is a California native perennial found in the Klamath Ranges, Cascade Range foothills, Sierra Nevada, southern California mountains, and eastern Sierra Nevada in boggy areas and shaded streambanks at elevations of 1,200 to 3,500 meters. Flowering from July to August, this delicate plant produces white to pink flowers 5 to 8 millimeters long with a broadly club-like stigma. Growing with sprawling, thread-like stems 8 to 30 centimeters tall and a matted habit, it has a purple-tinged appearance in its upper portions. Its sessile leaves are broadly elliptic near the base, becoming linear and widely spaced towards the stem tips, measuring 5 to 25 millimeters long with obtuse tips. The plant produces slender fruits 20 to 50 millimeters long, with pedicels typically longer than the fruit itself.
