Marsh gumplant

Family: Asteraceae · Type: shrub · Native

Marsh gumplant is a California native shrub found in the San Francisco Bay bioregion in tidal wetlands at elevations below 10 meters. Flowering from May to December, this plant produces yellow flowers in heads with 16 to 56 ray flowers measuring 12 to 17 millimeters long. Growing 1 to 2 meters tall with erect, woody stems that become woody in the lower one-third to half of their length, it has an upright, robust structure. Its leaves are glabrous, generally tapered to the base with acute tips, creating a distinctive architectural form. The fruit is 5 to 7 millimeters long, contributing to the plant's compact and structured appearance.
