Sclerolinon digynum

Digynum flax

Family: Linaceae · Type: annual · Native

Digynum flax is a California native annual found in the Klamath Ranges, Cascade Range, and Sierra Nevada in vernally moist meadows at elevations of 1,000 to 1,800 meters. Flowering from June to August, this plant produces bright yellow flowers with delicate petals in small clusters. Growing with erect, smooth stems 10 to 20 centimeters tall, it has a slender and upright form. Its opposite leaves range from 5 to 16 millimeters long, with lower leaves entire and upper leaves often lightly serrated, forming a delicate green backdrop for the yellow blooms. The fruit develops as a unique capsule with a rough surface that eventually breaks into four closed seed segments.
