Coast Barrel Cactus

Coast barrel cactus (Ferocactus viridescens) is a stout, ribbed cactus in the family Cactaceae, native to coastal sage scrub and chaparral communities of extreme southern California and northern Baja California, Mexico. It grows on rocky slopes, canyon walls, and coastal bluffs within a few kilometres of the Pacific coast, favouring thin soils and south- or west-facing exposures. This barrel cactus reaches up to 1 metre in height and diameter, bearing dense clusters of stout red or pink spines and yellow to greenish-yellow flowers that bloom in late spring and summer. Fruits are yellow and edible when ripe, historically used as food by Indigenous Kumeyaay people. The coast barrel cactus is threatened by illegal collection for the horticultural trade, urban sprawl around San Diego, and invasive grasses that increase fire frequency in chaparral. It is assessed as Least Concern by the IUCN, but populations in California are considered vulnerable due to limited range. The species is legally protected under the California Endangered Species Act and the Convention on International Trade in Endangered Species (CITES).
