Columbian windflower

Family: Ranunculaceae · Type: perennial · Native

Columbian windflower is a California native perennial found in the Klamath Ranges, northern Coast Ranges, and northern Coast Ranges Hover in open to shaded conifer forests at elevations of 100 to 2,000 meters. Flowering from April to July, this plant produces white flowers with 5 sepals 15 to 25 millimeters long, creating a delicate bloom against its verdant habitat. Growing 10 to 30 centimeters tall with a spreading, slender rhizome, it develops erect stems with sparse bristly or glabrous surfaces. Its leaves are typically few, with ternate blades and petioles 10 to 15 centimeters long, featuring leaflets similar in size and shape to its involucre bracts. The plant produces a compact spherical fruit cluster approximately 9 to 12 millimeters wide, with individual fruit bodies 2.5 to 4 millimeters long.
