Biarum carduchorum

All this talk about Dracunculus blooming almost caused me to miss the
flowering of one of its tiny relatives. Biarum carduchorum is blooming
today. This one bloomed at about this time last year, too. 

That puzzles me. Most plants bloom at the beginning of the growing season,
and their developing seeds have the advantage of clement conditions. This
Biarum carduchorum blooms as the plant is about to enter summer dormancy.
Last year I expected the plant to leaf out again shortly after it bloomed -
but it didn't. Here it produces leaves in the autumn, these leaves persist
during the winter, and in mid to late spring they die down.  

Can anyone tell us anything about the conditions under which this plant
grows in nature?
