Robin Attrill introduced Oxalis when it was the Topic of the Week. His 
introduction is well worth reading along with some of the responses to it.


There is excellent information on the wiki Oxalis page. Especially check 
out Michael Mace's post:


Michael Vassar also did a Topic of the Week introduction for the IBS 
list when I was in charge of it, but I don't seem to have kept what he 
wrote and since it was a private list, it wouldn't be available on the 
Wayback Machine. I heard Michael Vassar speak a couple of times and one 
of the things I remember was that some of the species needed to be 
planted deeply if you wanted them to flower. I don't know if anyone else 
would remember which ones, but as suggested height is one clue and 
probably size of the bulbs as well. You certainly wouldn't plant Oxalis 
hirta 'Gothenburg' with its huge bulbs in a 3 inch pot. A few of the 
"shy bloomers" started flowering for me once I started growing them in 8 
inch deep pots. Also as Mike says in his post referenced above planting 
in August here in Northern California has resulted in better flowering 
for the fall flowering bulbs. I noticed today that two of the earlier 
ones have buds. In Mediterranean climates when everything is brown and 
dry this time of year (and burning in a lot of places unfortunately) 
these early flowering Oxalis really lift your spirits.
