Common names: pampasgrass; white pampasgrass
Cortaderia selloana (pampasgrass) is a large perennial grass (family Poaceae) found along the coast of California, and in the Coast Ranges, Central Valley, Western Transverse Ranges, and Mojave Desert. Pampasgrass favors dunes, bluffs, coastal shrublands and marshes, inland riparian areas, and disturbed areas. 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. Pampasgrass quickly colonizes bare ground, but establishment is generally poor where the seedlings must compete with other grasses or sedges.Cal-IPC Rating: High
