I've been looking for a source for this myself. Saul's Nursery (wholesale only) has a fine specimen about 10 years old in the full sun out at the Swamp, but they don't sell them...

Interesting. Where is Saul's nursery located?

Saul's is at 1115 W. Nancy Creek Drive Atlanta, GA 30319

But, as stated, it is wholesale to the trade only. And, they don't stock Korean firs, they only have one in their small demonstration garden.

Try Picidilly Farms. They specialize in conifers.
Call first. I think they are only open on certain days.

Here is a link that might be useful: Korean fir

I was thinking Picadilly Farms also. I went through their conifer display garden a couple of months ago, but I can't remember if they had any Korean Firs. GardenWright Nursery in Cumming also has some harder to find conifers. I'm more concerned right now with getting feedback from someone who has actually grown it in our climate. I'm wondering how well it does down here.
