>size and in shape a bit too. That is certainly true of forms of >Oxalis purpurea, Oxalis flava, Oxalis hirta. >http://pacificbulbsociety.org/pbswiki/index.php/… > I have 2 pots with both yellow and pink flowers (and very different leaves). Must try and separate out the hirta and flava as they go dormant next year. Not a good idea to repot both at the same time. Both increase readily. Great plants in the daytime but useless to take to evening meetings when the flowers are closed. Brian Whyer, Buckinghamshire, England, zone ~8 ish
