Johannes-Ulrich Urban asked, >Has anybody ever managed to create an Oxalis hybrid? or harvest seed at all? >(except the devilish annual ones, of course) There is a well-known hybrid between (I think, this is just from memory) O. enneaphylla and O. laciniata called 'Ione Hecker'. It is a floriferous plant, dormant in winter and flowering in mid to late spring with big white flowers striated with violet. I grow it in a pot plunged in some big planters that I keep on my covered deck for fussy alpines. It is often grown by alpine gardeners. It would not be suitable for very warm regions. I have harvested seed in the wild from several Oxalis species, but the only one I got to grow was O. squamata, a tap-rooted species from the lower Andes in central Chile. It has fleshy, glaucous leaves and produces bright rose-pink flowers all summer. It is marginally hardy here so is not a weed problem, but I would not plant it in California.
