Gardens of Alcatraz

For 150 years, a succession of soldiers, families of correction officials, and inmates cultivated gardens hewn on the rocky, windswept island of Alcatraz. For ten years, the Garden Conservancy led the effort to rehabilitate the Gardens of Alcatraz in partnership with the Golden Gate National Parks Conservancy and the National Park Service. In 2014 the restoration project completed successfully. Visitors once again are able to enjoy and gain insight into the role these plantings played in the lives of people who inhabited this harsh environment. The Golden Gate National Parks Conservancy is now managing the gardens locally.


The Gardens of Alcatraz receive a Garden Conservancy Garden Futures Grant to purchase an all-terrain vehicle for the garden’s horticultural staff and volunteers.

After successful completion of the Historic Gardens Project led by the Garden Conservancy, management of the Gardens of Alcatraz transitions to local management under the Golden Gate National Parks Conservancy.

Alcatraz is designated a National Historic Landmark.

The Golden Gate National Recreation Area is established, placing Alcatraz under National Park Service management with increased public access.

The island is occupied as part of the American Indian protest movement. Many of the structures are destroyed by fires.

The penitentiary is closed and the island is transferred to the Governmental Services Administration. Although a caretaker stays on, the gardens begin to decline with invasive overgrowth covering many beds and paths.

After most of the officers' cottages are demolished, staff families and inmates plant cutting gardens in the building foundations.

Freddy Reichel, the warden's secretary and an avid gardener, convinces the warden to allow the federal prisoners to garden and seeks advice and plants from prominent California horticulturists. For the next 15 years three inmates in particular, Dick Franseen, Elliott Michener, and Jack Giles, play important roles in developing and tending the west side gardens, the water tank area, and the gardens and greenhouse at the wardens house.

The island is transferred from the military to the Federal Bureau of Prisons.

Using plants and seeds donated by the California Spring Blossom and Wild Flower Association, prisoners plant hundreds of pounds of nasturtium and poppies, shrubs, and 300 trees (eucalyptus, pines, cypress, and giant sequoias).

After construction of a new cell house, inmates build and plant gardens on the island's west side near the guard tower.

The military post becomes exclusively a military prison.

Gardening becomes an important aspect of daily life for officers' families and prison inmates as some of the original gardens give way to a row of officers' cottages, each with its own garden plot.

A military prison is established. Soil is brought in from nearby Angel Island and, along with the dirt, comes seeds of wild blackberry, coyote brush, and blue elderberry. Barley and ice plants are planted to control erosion, and a few gardens are created near what will become Officers' Row.Citadel garden, 1869. Photo: Eadweard Murbridge, Bancroft Library
