[Cal-IPC] Invasiveness: Limonium duriusculum (European sea lavender) is a perennial herb (family Plumbaginaceae) with tiny purple flowers and oval-shaped leaves found primarily in the San Francisco Bay area and central and south coast of California. Populations extend into the coast ranges. Limonium duriusculum is similar to another co-occurring, non-native sea lavender (L. ramosissimum) but can be differentiated by its obovate, blunt-tipped leaves and less compactly-arranged flowers. Intermediate forms have been found in the SF Bay area. It is native to the Mediterranean and favors marshes, scrub and chaparral, and riparian and bottomland habitat. It spreads via seed. Human activities and water help disperse the seeds. Cal-IPC Rating: Moderate (link added by Mary Ann Machi)
