    This information is not entirely correct. Ruellia peninsularis is NOT native to Southern California. It is native to Baja California (that's in Mexico) and to the Sonoran desert which is primarily in Arizona and Mexico and touches southeastern California. The desert climate in southeastern California is dramatically different from the Mediterranean climate in Southern California.
