Dear Katy, First welcome to the PBS list! You will find a number of us here who are very fond of Oxalis in spite of its weedy tendencies. I have 3 species in bloom right now all courtesy of Uli in Germany (sent in the past when you could do that without a certificate). My experience with Oxalis has been that like many other bulbs I grow that some of them choose not to come up some years. When I dump the pots, they are there and look fine. I once asked about Moraeas, what are they doing down there and Rachel Saunders speculated, "absolutely nothing." Since then I have dumped pots out where there was no activity and found that quite often that was true. Other times however (not usually) bulbs had roots and were growing but never broke the surface. Could they be too deep? I don't know but remain curious. I am afraid I grow too many things to have kept track of what has happened to all of those who are sulking or waiting for conditions more to their liking. Some Oxalis that hasn't come up one year has the next, but others when examined closely have a hard shell that encloses nothing. Do the acorn-like things in your soil look like what you brought back? Oxalis is very variable in the forms of its under ground storage organ. If this looks like the same thing you remember you could try to mimic its natural cycle. Lee Poulsen has plotted some rainfall graphs and I think there is at least one Mediterranean one here and the link to another source where you might find the islands: http://pacificbulbsociety.org/pbswiki/index.php/… It might come up in the fall as I'd assume it would be winter growing. It wouldn't hurt to try if it was something you really wanted. Which ones do you grow successfully inside? I'd think a lot of the South African species wouldn't get enough light indoors. I know ones I donated to the Mendocino Coast Botanical Gardens where some large trees from adjacent properties are beginning to shade the area where the bulbs are displayed got very leggy. I am sure that many of our members would be interested in knowing what works. I will be sharing more of my extras with the BX soon and people from colder climates could try them inside if it would work. One I have a whole lot of is Oxalis glabra that is blooming in Australia right now. Lyn Edwards just added her picture to the wiki: http://pacificbulbsociety.org/pbswiki/files/… One of the nice things about her picture is that you can see both leaves and flowers. So often getting both in focus is tricky and since the leaves are much more variable than the flowers it is nice to see both (and in one picture.) This one produces a lot of very tiny bulbs or are they corms? I think they'd be too tiny to slice through to find out. You'd think they wouldn't be big enough to bloom, but they do. We've concluded with as many offsets as it makes that growing it in a container is the way to go. They might be weedy in warm climates and wouldn't survive the cold in cold ones.
