The major Seattle area independent nurseries are

Molbak's, in Woodinville
Swanson's, in Seattle
Wells-Medina, near Bellevue

There are multiple others in the area that might also have it. Maybe you'll just have to work your way through a directory listing, hope you hit pay dirt.

Or order through the mail.

Here is a link that might be useful: Viburnum carlesii - Koreanspice Viburnum - ForestFarm

I found one in a nursery about 15 miles from here! I couldn't believe it when she said tentatively it was a compactum...Perfect! It's a good size plant, wrapped in burlap about 2 1/2 to 3 feet tall.

Now I need to find a nice vine. =)

West Seattle Nursery has some - their prices are great.
