Amana edulis. Not the only edible tulip either, though it is hard to find information on which are eaten, and where. There is a story that I've mostly forgotten about Clusius or someone cooking up a big batch of them before he saw the flowers. I recently read that the bulbs of wild Muscari comosum and M. racemosum are delicacies in Puglia (and I would guess, elsewhere in their range as well). I may try some in the herb bed.
