Here are some photos of the little seedlings that I found yesterday, and a photo of an older one.
I discovered this little fellow whilst mulching a bed that contains the peonies Lady Alexander Duff, August Dessert, Fancy Nancy and High Fashion.
This one found in the same bed as the one above. Slightly larger seedling.
Who knows what they will look like
This one is at least one year old, and will be moved to a holding bed later this summer.
