Description
Crocosmia x crocosmiiflora (crocosmia or montbretia) is a perennial (family Iridaceae) found along the coast of California and in the San Francsico Bay region. It is native to southern Africa, and has established itself in wildlands throughout the Hawaiian Islands.
Crocosmia is a commonly cultivated ornamental plant, and is most commonly found near urban areas. It prefers disturbed areas, including roadsides, coastal scrub, prairie and forests. Crocosmia is a superior competitor for water, light and nutrients, and it excludes native plants by growing in dense patches. It reproduces using seeds and underground corms. Upon introduction to a new area, crocosmia spreads slowly at first, then more rapidly as the species becomes established. (From Cal-IPC)
