Purple Shamrock

Actually more of an oxalis regnellii, I believe. It is in recovery from lack of watering.
I had to rescue this from my son's house, as he has suffered a detached retina and has had emergency surgery. He must lie still for two weeks face downwards. So in addition to him, I am also nursing SWMBO with her badly broken humerus and now I can add this plant to the list.
Good news is that Lily the Dobermann has stopped limping!
