Well since no one else is answering I'll submit my 2 bits, which is that if you don't plant them, they definitely won't grow! I have made every bulb mistake in the book; I buy them and then forget them in the bag in the rain, or order them and leave them on the dry porch... I plant them when I find them, and some of the bulbs make it, and some even bloom. And if they don't bloom this year, then perhaps next, if they survive the wait you've imposed and you now plant them and give them a chance to put up some foliage this year to garner strength for the future.
