Who knew that for decades San Francisco's famous Alcatraz prison harbored not only notorious criminals, but also a collection of lush gardens?
The Gardens of Alcatraz were planted more than 150 years ago for the benefit of those serving duty, those serving time, and the San Francisco residents who didn't want to look at the stark island eyesore in the middle of the bay. Over several decades, officers and inmates carved terraces, built greenhouses, and cultivated gardens on the rocky windswept island.
Abandoned after the prison closed in the early 1960s, the Gardens of Alcatraz are a study in survival. Many of the hardy and humble Mediterranean plants chosen by the prison warden (with advice from the California Horticulture Society) in the 1930s proved to be good choices for the harsh environment as they not only survived, but thrived in the four decades of neglect. In 2003, the Garden Conservancy, the Golden Gate National Parks Conservancy and the National Park Service joined forces to restore and maintain the historic gardens. Set in the crumbling foundations of old prison building and walls, these enchanting gardens are worth a visit.

Surviving plants include yellow bush lupines, pink Centranthus ruber, and pelargoniums. Photograph by Elizabeth Byers.
