Alsike clover

Family: Fabaceae · Type: perennial · Not Native

Alsike clover is a naturalized perennial herb found sporadically in northwestern California and disturbed areas at elevations below 1,500 meters. Flowering from May to October, this plant produces pink flowers in compact clusters 1.5 to 3 centimeters wide. Growing with stems that range from sprawling to erect and reaching moderate heights, it develops a somewhat glabrous appearance. Its leaves feature three leaflets that are 1 to 4 centimeters long, elliptic to obovate in shape, with prominently veined lance-ovate stipules. The flowers are distinctive, with pink corollas 6 to 11 millimeters long and calyxes 3 to 5 millimeters with lanceolate lobes that are nearly as long as the flower tube.
