About Alkali Bulrush (Bolboschoenus maritimus) Bolboschoenus maritimus is a species in the Cyperaceae (Sedge) family known as Alkali Bulrus. This is a strictly wetland plant that is highly tolerant of alkali or salty conditions. It is found throughout California, wherever these conditions exist. It spreads vigorously by rhizomes and will rapidly fill in wherever there is sufficient water. This plant is unlikely to be used in residential gardens but could be useful if you are creating a bioswale.
