Mike, I'm so glad you were able to find a nursery that might be able to get it for you.* You might want to do a google with the botanical name like this:
Arbutus unedo 'Elfin King'
I found a couple of nurseries that say they carry it.* Of course you'll want to check their references.* :)*
Thanks for letting me know how it's going.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
