Synonyms: Cortaderia atacamensis

Common names: jubatagrass; pampasgrass; pink pampasgrass

Cortaderia jubata (jubatagrass) is a large perennial grass (family Poaceae) found along the coast of California and in the Coast Ranges. Jubatagrass favors dunes, bluffs, and disturbed areas, including inland areas where temperatures are moderated by fog. It was introduced as an ornamental plant and for erosion control. Each plume produces up to 100,000 seeds that are widely dispersed by wind and develop without fertilization. Jubatagrass quickly colonizes bare ground, but establishment is generally poor where the seedlings must compete with other grasses or sedges.
