Very interesting post, Christiaan. I'm glad this side of you won because it's these kinds of informative posts that make this forum valuable. Oxalis hirta grows very well for me, even though I do not give it the best care like other species. It even escapes the Oxalis rust plague that I have been battling (and winning this year with a drier winter). I have noticed some seedlings spread around, so I think it does make seeds, but probably not many. Some bulbous American Oxalis species do make seeds. For instance, the Californian native O. oregona makes huge capsules and gigantic seeds (see photos on the wiki). The Mexican magnifica/lasiandra/nelsonii species complex can cross with each other. I've noticed seedlings of these around my collection too. Invariably, when you have the weedy O. stricta group and a collection of other American Oxalis, you will find that they also cross. I've been very much tempted to save some of the more interesting looking ones, but didn't because who knows what kind of super weed I could be selecting for.
