Alcatraz Island has no native flora. Upon the arrival of the U.S. Army and Lighthouse Service, the island was a barren, bird guano encrusted rock. All the soil and plants you'll find on Alcatraz today were brought to the island by people.
Today, the restored historic gardens are lovingly maintained by a team of volunteer gardeners in partnership with the Golden Gate National Parks Conservancy. Today these gardens are watered through a rainwater catchment system.
View the gallery below to take a up close and personal tour of bit of the beauty the Rock has to offer.
