In Florida, Solanum mauritianum has become naturalized and common only at one site in Pasco County. It also occurs frequently in southern California from Santa Barbara south to San Diego with urban waifs in the Bay Area. It appears to be spreading into relatively undisturbed riparian areas in the San Gabriel Mountains and may become a widespread pest.
