Potatoes in December?

Yup...the freeze killed a couple of the plants that were planted in Sept. and when I went to pull them out yesterday, there were 4lbs. of potatoes in the ground....yay! Amazingly the younger plants (not yet up in this photo) weren't affected. More plant out of the ground made them more vulnerable?

I really didn't think that they were mature enough to get a harvest, so was pleased that our attempt to salvage sprouting potatoes hadn't been entirely in vain. Next year we may go ahead and plant more spuds early in the fall so that we can have home-grown tots for Thanksgiving and Christmas.
