This particular leaf is probably better described as a bowl. A much smaller Hosta leaf (about 8") in a natural concrete finish. The scallop shape of the Hosta works well as a water bowl. As with the larger basin style leaf this size will hold water long enough for the birds to wash and get a drink...hopefully not in that order.
The Goose loves it for a refreshing pick me up especially after the birds have been washing in it...probably some sort of delicacy in doggy world. Like cold bird soup.
