Oxalis palmifrons is one of my most favorite species of Oxalis. I cringe at the thought of adding them to a pot of soup, although it caused quite a fervor in my culinary curiosity. Oxalis pes-caprae is a weed here and grows in huge masses in some places. I must admit I have a very soft spot for these intruders. Perhaps I'll raid some of these patches this year for what sounds to be quite interesting white roots. Thanks, Christiaan!
