Common names: Algerian sea lavendar
Limonium ramosissimum (Algerian sea lavender) is a perennial plant (family Plumbaginaceae) that can be found in the San Francisco Bay, Carpinteria marsh (Santa Barbara County), Orange County, and San Diego County. Historic records include Riverside County as well. It is an ornamental escape that is native to the coastal Mediterranean and can grow in coastal marshes as well as inland wetlands.
This species reproduces by seeds that can retain the ability to germinate after two weeks floating in salt water. It was previously listed as the “provinciale” in our Inventory but its subspecific identity is unclear and many collections recorded across California are not associated with subspecies. In both the SF Bay and southern California, Limonium ramosissimum co-occurs with another closely related invasive sea lavender, Limonium duriusculum.
