I found these too. They were planted around a bed in the lawn that has a rose that has never done well in it. I gave up on crocus because the squirells, rabbits, deer or what ever get to them. They come up fine and the chomp they're gone.
I think some of it has to do with a southwest exposure and the garage protruding out from the house so it sort of forms a courtyard but not quite. Its just kinda sheltered. Daffodils are coming up in the back that are planted among the trees and have buds but the ones in the front just have leaves.
Anyone elses garden showing life yet?
