Narrow leaf collinsia

Family: Plantaginaceae · Type: annual · Native

Narrow leaf collinsia is a California native annual found in the Klamath Ranges and northern North Coast Ranges in open conifer forest at elevations of 200 to 2,000 meters. Flowering from May to July, this plant produces white to blue-purple flowers 8 to 12 millimeters long with a distinctive square-shaped throat pouch. Growing 10 to 40 centimeters tall with spreading stems, it features linear leaves more than six times longer than wide with margins rolled underneath. Its leaves are generally narrow and elongated, with delicate margins that curl slightly inward. The flowers have an unusual structure with upper filament lobes that bulge slightly away from the throat opening, creating a distinctive botanical profile.
