Epilobium ciliatum subsp. glandulosum

Family: Onagraceae · Type: perennial · Native

Glandular willowherb is a California native perennial found in the Klamath Ranges, northern California Coast Ranges, Cascade Range, Sierra Nevada, Transverse Ranges, and Warner Mountains in often shaded streambanks, seeps, and meadows at elevations below 3,500 meters. Flowering from June to October, this plant produces delicate pink to rose-purple flowers 4 to 14 millimeters long in dense, leafy racemes. Growing with fleshy stems 20 to 110 centimeters tall, it has a distinctive strigose texture with glandular hairs toward the upper portions of the plant. Its leaves are narrowly ovate to ovate, with minimal size reduction from lower to upper stems. The plant's underground shoots are scaly and rarely leafy, contributing to its unique growth habit.
