Details: The mountain provides habitat for several species of rare and endangered plants and butterflies. The endangered San Bruno Elfin Butterfly inhabits this mountain and a few other locations. The distinct Franciscan fog zone of San Bruno Mountain set it apart from other California coastal areas. Look for plants such as Coast rock cress (Arabis blepharophylla), Franciscan Wallflower (Erysimum franciscanum), Montara Manzanita (Arctostaphylos montaraensis), Pacifica Manzanita (Arctostaphylos pacifica), San Bruno Mountain Manzanita (Arctostaphylos imbricata), San Francisco Campion (Silene verecunda) and San Francisco Owl’s Clover (Orthocarpus floribundas).
