The glad corms themselves are no doubt fine. The remaining foliage should be adequate to reenergize. Leave them in the ground yet for as long as possible.

Then read up on storing glad corms - lots of information on the internet. If you feel it's worth the time and effort, go for it. I always had marginal results the few times I attempted to winter them over in storage - mold or rot or totally dried out, or foliage but no blooms the second season... So any year I wanted glads, I'd just buy fresh ones. They're inexpensive and readily available just about anywhere.

Others have had good luck in saving from year to year, so everybody's mileage varies.

Thanks - I'll leave them in the ground until mid October and over-winter them to see what happens. Likely I'll also buy some new ones as well, just in case they don't sprout.

I had overwintered a bunch last year and it seemed like they all came up. Rabbits of course devoured most of those, but a couple that were less touched actually started flowering (though the rabbits chopped them down pretty quick).
