Information about  Oxalis pes-caprae from other sources

Bay Nature: ... a weed native to South Africa that was transplanted to California early in the 1900s, ... Oxalis crowds out native wildflowers for light and space, and prevents other plants from gaining a foothold in the land.

Weed Control in Natural Areas in the Western United States: Viable seed never has been documented in the United States, and rarely has it been seen anywhere else in the world.
