Wow, that was close timing, Mary Sue!  

You mentioned, I note, legacy bulb pages in thw wiki. Can you point me to
those pages as I did not see them under Oxalis or contained within other

Rodger's advice is very good.  It really does depend on where you live. But
I do think having a note  on the wiki of what can be a problem in certain
climates is very helpful. I'm very fond of Oxalis convexula which has
succulent leaves and is very dainty, but don't usually have any to share
with the BX and it certainly isn't weedy for me like it is for Andrew. But
when I've had Oxalis make small babies like Andrew described, I've tossed
them quickly. Oxalis obtusa shows up in a lot of my pots, but hasn't
returned in the few experiments I made of growing it in the ground even
though Lauw suggests doing this would not be a good idea. I don't know why
it didn't do well in the ground when it can be pest in pots, but I have
found that not every South African winter rainfall bulb does well growing in
my garden. Some only survive in pots. alas. Oxalis purpurea which Diana
Chapman once suggested would make a nice lawn is one in my Northern
California garden that once planted out is difficult to get rid of. But I
imagine in colder climates it might not return. And a friend who works in a
garden setting said it depended on the variety whether of not it did too
well in the ground. 
Oxalis pes-caprae is a menace in the wild where I live and in many other
parts of the world, but probably not everywhere.

The legacy bulb pages on the wiki list plants that Kathleen Sayce found in
her research had naturalized. Puttting all that information on the wiki took
me many months and I didn't transfer the information she found to the genus
wiki pages for the species she found as I didn't have time. That job is open
for anyone who wants to volunteer to do it.
