Hi Ken, Looks like you've got more than 1 weedy Oxalis in that pot! :) The purplish one is the evil O. corniculata group that's weedy basically everywhere. The succulent is O. megalorrhiza which has a thickened tap-root. Make sure you pull the whole tap-root out if you want to get rid of it. I feel torn about this species because I'm fond of it but it can be weedy, especially in succulent collections.
