Their growth is triggered by autumn rains. They have evolved to begin growing when the leaves on deciduous trees have fallen and to complete their growth when those same trees are once again covered in leaves.
Sorry, but the dried bulbs sold in all sorts of outlets are generally dead. Either buy them freshly dug at any time of the year or as growing plants.
The reason for them dying when dried is because they do not have a water retaining skin in the same way as Narcissus and Tulips do, so they dehydrate very easily.
