Nhu, Thanks for the info, I wonder if such oxalis stricta/corniculata/Mexican hybrids would even make seed, I think they would be pretty wide crosses and therefore could be sterile. In theory if such crosses could occur readily I would think that they already exist wherever any compatible bulbous New World oxalis species occurs, since O stricta and corniculata are so ubiquitous.

(Rick Buell) Hi Ernie, I did not notice any bulbs from the O. stricta hybrid, but I am more worried about them being seedy. Could you imagine hybrid vigor in O. stricta/corniculata hybrids? Just can't let that happen.
