At the San Diego Zoo we realize we have the ability to help save and preserve many species that are threatened in their native habitats. One of our efforts can be found at our Hawaiian Native Plant Garden, located at the top of Center Street. Some of the more notable species you will find here are: the koa tree (Acacia koa), loulu palms (Prichardia spp.), and the cabbage-on-a-stick plant (Brighamia insignis). These are just a few of the plants we grow in the Hawaiian Native Plant Garden. We are always adding new ones and growing species in our off-exhibit greenhouse. For us, it is a thrill to try to create an area in the Zoo that mimics the Hawaiian Islands, right down to the lava rocks!
