The Los Angeles area is rich in native plant species due in part to a diversity in habitats, including beaches, wetlands, and mountains.
The most prevalent botanical environment is coastal sage scrub, which covers the hillsides in combustible chaparral. Native plants include: California poppy, matilija poppy, toyon, Coast Live Oak, and Giant Wildrye. Many of these native species, such as the Los Angeles sunflower, have become so rare as to be considered endangered.
Though they are not native to the area, the official tree of Los Angeles is the Coral Tree (Erythrina caffra) and the official flower of Los Angeles is the Bird of Paradise (Strelitzia reginae). Mexican Fan Palms, California Fan Palms, and Canary Island Palms can be seen throughout the Los Angeles area, despite the latter being non-indigenous to Southern California.
