Thankyou Gardengus! This makes me nervous because I wonder if I have eaten this purslane before it had flowered. I think I've seen this plant before and remember seeing tiny bud shapes (for flowers) and remember thinking it might be a different plant other than purslane. Then seeing the white flowers, not just one but maybe up to 10 tiny ones per plant really thew me. Thanks for your help. I'm traveling so don't have plant still with me. I have seen the yellow flower of purslane but am not sure if this plant also had 5 petalled flowers. It is still a mystery to me and quite a mysterious look a like!
