Wow, thanks to everyone who has responded so far, I have a lot to go on... I do have a nice soft pink (not white) Oxalis which is similar to rubra, crassipes etc., but it is a real terror, it can escape pots either through the drain hole or by spilling over the edge and forming bulbils in mid air... It is at least as dangerous as O. pes caprae, but shorter - small consolation... Oh, BTW my original start of O. rubra (pink) came from the BX - thank-you somebody!! Chad Schroter
