Hi Alberto, Ron & Angela! The reason I am asking about the multipetal / double-flowered Oxalis is because I found a clump of yellow double-flowered Oxalis when I was hiking in the Oorlogskloof area last October. I collected a few bulbs, and they have started growing now! I was very excited about my discovery as I have never seen or heard of double-flowered Oxalis, but now it seems they are not as rare as I thought. Oh well! Thanks for the help! Pieter South Africa
