Sparganium eurycarpum
Broadfruit bur reed
Family: Typhaceae · Type: perennial · Native
Broadfruit bur reed is a California native perennial found in wetland habitats, typically growing in marshy areas and shallow water. Flowering from June to August, this plant produces distinctive white to cream-colored flower heads with separate staminate and pistillate clusters. Growing robustly to 2.5 meters tall, it develops thick, triangular stems that emerge from the water or nearby moist ground. Its leaves are thick and three-angled near the base, becoming flat or keeled toward the tips, with blades that can vary from thick to thin along the plant's height. The fruit is notable for its obconic shape, measuring 5 to 9 millimeters long with 3 to 6 distinct angles and a short 1 to 4 millimeter beak.
