Oxalis corniculata. Did anyone else grow up calling this little yellow flowering creeper with heart-shaped leaves "sour grass"? I remember chewing on the stems of freshly picked sorrel as a kid, and the taste was reminiscent of pickles. (Caveat: I do not recommend taste-testing wildflowers without a certified nature guide along, and I especially do not recommend ingesting or even tasting any wildflower that may be in an area that has been treated with pesticides or other chemicals.)
