Yellow wood sorrel

A little wildflower:

This may be Oxalis stricta, or another yellow sorrel with a clover-like leaf.

  1. This flower is quite common here, but I’ve rarely seen one as lovely as this; your attentiveness paid dividends. One of our state’s native pink species is common here, too, and in the east Texas piney woods, I found a yellow species with slightly larger flowers and little red stripes in the center.

    Here’s an odd tidbit for you: the active ingredient in the cleaning powder known as Barkeeper’s Friend is oxalic acid. It’s one of the best ways there is to remove rust. I use it all the time, especially on fiberglass. Make a wet paste, cover the rust for a while, and wash it off. Easy. Now I’m wondering if a paste of the flowers would do the same thing. I guess I’ll have to wait for spring to experiment.

    • I’ve used Barkeepers’s Friend for years for removing stains and rust – but I didn’t know about oxalic acid in the ingredients. And I never made the connection between Oxalis and oxalic acid. So now I have two experiments to do: tasting sorrel, and trying it for cleaning. I won’t have to wait until spring, it’s still blooming here.

      • I was introduced to oxalic acid as a wood cleaner first, then I learned about its other applications. I’ll have to watch — as our weather cools, we may have more oxalis plants appearing.

      • I’ve used oxalic acid for cleaning my deck. I’ll try the taste test first, I suspect that the leaves won’t be effective for cleaning – maybe I’ll try it on stainless steel.
