Weeding season is here

The much anticipated winter rains that bring a lush green to the island mark another “season” in the gardens – the weeding season. The most prolific weed on the island is Oxalis pes-caprae, commonly known as sourgrass or Bermuda buttercup. It is native to South Africa and highly invasive in California, especially along the coast.

How oxalis came to be on Alcatraz is not known. However, it is thought that the bright yellow winter flowers of oxalis were ideal to plant with the summer blooming pink Persian carpet, Drosanthemum floribundum.

While this planning of sequential garden bloom is clever, past ornamental plant introductions often turn out to be problematic choices.

To maintain the Persian carpet and to keep it from being choked out, volunteer gardeners will be spending countless hours on the south facing cell house slope from now until April.

Weeding oxalis is no easy feat but not without rewards. Oxalis grows from a corm from a depth of one inch to over nine. Digging out the corm is the key to removing the weed once and for all, and the satisfaction of pulling out the entire corm is very rewarding. I often find myself holding up the offending corm and showing it off proudly to the volunteers, as usually it’s only other weeders who can fully appreciate the accomplishment. In addition to the sheer pleasure of weeding for hours, enjoying views of San Francisco and the Golden Gate Bridge, chatting with visitors who are also admiring the view, and occasionally eavesdropping on conversations cannot be beat.

Volunteers Uncover Hidden Terraces

While Alcatraz is a relatively small 22.5-acre island, a few historic gardens tended long ago remain hidden; they have yet to be cleared of overgrowth vegetation, documented, and perhaps one day restored.

This past weekend, volunteers from the Bay Area Whaleboaters Association worked to reclaim a set of terraces that lead from the dock to the parade ground. These terraces were first gardened by Freddie Reichel in the early 1940s. Mr. Reichel was the secretary to Alcatraz Warden Johnson. Impressed with the gardens left by the military, he worked in his spare time to maintain their beauty. He began to tend these terraces behind his home.

Prior to any removal of vegetation, we investigate the history of the area. There should be some documentation that the area was once a garden. Evidence of a past garden can be found in historic photos, oral history interviews, old maps of the island, and existing ornamental plants and hardscape features. In this case, old photos, surviving ornamental plants, and extensive terraces confirmed our belief that the area had once been gardened.

The Whaleboaters revealed dry-stacked terraces and cleared the staircase that was becoming covered with eucalyptus leaves. They made a few interesting discoveries – a pink radio, several rubber boots and surviving ornamental plants such as Euonymus japonica and an unidentified rose.

The Whaleboaters did a fantastic job revealing this hidden corner of the island. From the dock, visitors can see for themselves the newly revealed terraces and the staircase that once led to the parade ground.
