I found a nice pack of these at a local garden/nursery a few weeks ago. I haven't bought them yet. I'm drooling over them as they are probably some kind of requisite to a cottage garden. Gosh, they are just lovely, only 2 bucks for a pack...and are going to look real nice turning shades of verdigris in our Coastal Cottage Garden.
Park Seed Co., shows and sells them as well.
It will be a finishing touch well worth the wait....
