Harkness' flaxflower

Family: Polemoniaceae · Type: annual · Native

Harkness' flaxflower is a California native annual found in the Klamath Ranges, northern Coast Ranges, Cascade Range, Sierra Nevada, and Great Basin in open flats at elevations of 1,000 to 3,200 meters. Flowering from June to August, this delicate plant produces white to pale blue flowers in small clusters with thread-like pedicels. Growing with slender stems 5 to 15 centimeters tall, it forms sparse, delicate branching structures primarily above the base. Its leaves are divided into fine, thread-like lobes 5 to 15 millimeters long, giving the plant an airy, delicate appearance. The small white or pale blue flowers are tightly nestled within the calyx, with stamens extending beyond the petals.
