Oregon Oxalis (or Redwood Sorrell) plants in the soft light of a redwood grove at Muir Woods National Monument, California.

In many places this intriguing plant covers the forest floor in the heart of Muir Woods National Monument. I’ve always just thought of it as “clover,” but I had this nagging suspicion that it might have a different name. It turns out that it is oxalis oregana, also known as oregon oxalis or redwood sorrell. This patch was located in a rather dark area beneath some large trees, and the water drops were left over from earlier rain. In my mind, this small but lush plant, carpeting the forest floor, represents the rich character of the undergrowth of the redwood forest.
