I harvested one of the ponds last week just before the bitter cold moved in, but I haven't tasted them yet. The corms were loosely connected in among the roots, but you could definitely remove them without killing the plants. Size was a bit smaller than I wanted, though, so i think they needed to grow longer. Next year I'll put them in in April or May.
I'll eat the largest and plant the smallest in the next week or so, and I'll try to get pictures then.
