Bassia hyssopifolia (fivehook bassia) is an annual herb (family Chenopodiaceae) found throughout California, except in high elevation areas in the northwestern region of the state and Sierra Nevada Mountains. It prefers wetland areas, alkaline habitats and disturbed places such as roadsides and fields. Fivehook bassia is acceptable forage for sheep in small amounts, but the foliage can be toxic in large quantities. The plant produces copious amounts of seed, but small populations can be controlled by mechanically removing plants before seed set. Mowing and grazing are not suitable control methods, as the plants commonly resprout from the base after such treatment.Cal-IPC Rating: Limited
