I keep telling myself that I should try to eat these some time since it is clear that they are a preferred food by almost any animal in the area. When I was redoing the edge of the North Garden there were many crocuses in there and so I gathered them and moved them so they could grow while I was working on that edge. Then right before I went to move them all back they were cleaned out by chipmunks (aka ground squirrels). It was a beautiful patch and I lost several hundred corms. To protect the corms from the animals you can plant them in a cage of wire mesh. After checking out the wiki I see that some are edible, but not all of them are, so be careful and know what is good before you do try them for a snack!
