I've had Oxalis adenophylla -- the ordinary form you buy dried in the 
fall, just like yours -- in my garden for about 15 years and it just 
keeps on trucking along. I planted some more new ones last fall 
(2002), bought cheap at an end-of-season markdown, and all (most?) of 
them leafed out and grew just fine this last spring.

As far as I'm concerned, this species is as tough as old boots and 
reports of difficulty with it puzzle me.

The older planting is in rather heavyish soil, the newer in quite 
sandy soil, but neither spot ever gets standing water in the winter. 
Not in full unabashed sun; shady in winter, noon sun in summer.

Let me hazard a guess: you kept the bulbs too warm, and fungal growth 
outstripped plant growth.
