Hi! I'm in Illinois, just outside of Chicago. I planted my perennial seeds in mid- November, after the first hard frost. But now we're in the middle of a freak warm spell. It was 61 degrees this past weekend, and all or most of the seed I've sown have already sprouted! Now, I know this warm spell can't last. My question is, if we finally end up with a frigid Chicago winter, will all these seeds be lost? Can they possibly survive until spring?
