Pre-treatment: Mechanical injury of the caryopis or covering layers or soaking seeds for 24 hours in water
Establishment: Seeds are collected between September 11th and November 4th. Mature inflorescences are panicles 2 to 8 cm long. Seed is 2 mm long and brownish grey in color at maturity. D. spicata var. stricta is found from the Great Plains region of North America to the Pacific coast; also in South America, Australia, Tasmania, and Tahiti. D. spicata is found in coastal salt marsh from Orange County, California to Oregon, and on Catalina and Santa Cruz islands.
