Narrow-leaved clover

Family: Fabaceae · Type: annual · Not Native

Narrow-leaved clover is a naturalized annual found in the central coast and southern coastal ranges in disturbed areas at elevations especially below 200 meters. Flowering in late spring, this plant produces pale pink flowers in cylindric spikes 1 to 5 centimeters long with distinctive needle-like, plumose calyx lobes. Growing with generally erect hairy stems, it forms an upright annual herb. Its leaves have three leaflets 2 to 4.5 centimeters long, ranging from linear to narrowly lanceolate with stipules that have bristle-tipped ends. The calyx is 10 to 12 millimeters long and becomes hardened in fruit, with unequal spreading lobes.
