Triglochin concinna

Arrow grass

Family: Juncaginaceae · Type: perennial · Native

Arrow grass is a California native perennial found in wet coastal meadows and salt marshes, forming loose tufts or mats at low elevations. Flowering from spring to early summer, this plant produces small greenish-white flowers in slender aerial racemes rising above its narrow leaves. Growing 10 to 60 centimeters tall with creeping rhizomes, it develops thin, round or semicircular stems that spread into loose clusters. Its leaves are fine and grass-like, typically 5 to 30 centimeters long and only 1 to 2 millimeters wide, with deeply two-lobed leaf tips. The fruit consists of six slender mericarps 3 to 6 millimeters long that fully separate when mature.
