Fritillaria pudica also (and I think more commonly) grows in acidic soils. 
It flourishes in my bulb frames, but few people in this area manage to keep 
it going in the open garden, however close to us it is native. I think it 
needs a drier winter. In nature, its habitat is slightly moist in fall, 
variably moist (often frozen) in winter, quite moist in spring, and very 
dry, as Rodger says, in summer. The plants usually grow on fairly steep 
slopes and banks in rocky soil. Olsynium douglasii and Erythronium 
grandiflorum are frequent companions in the Columbia Gorge, where F. pudica 
can be seen in flower in late March and April.

I believe the Dutch stocks are grown much like tulips, which enjoy a 
similar annual cycle.
