Don't know, but I have a friend with acres of land who looked into this commercially and decided against it.

Primary reason was the expense of the seed/juvenile trees for commercially viable produce.

His conclusion was it would take years to even have the potential to see a return on investment.

Sorry I don't have any specifics.

Yeah I guess its how you sell them...definite niche. Thats why I'm paying $359.00 for a 2" caliper Autumn Gold Ginkgo. The only way I was able to justify the cost, was for its amazing shape. Most globular, upright Autumn Gold or any Ginkgo for that matter that I've ever seen. I've seen others with minimal, irregular branching in the 1.5" caliper range for $180.00.

I've only seen one amazing mature Ginkgo ever...funny thing is its in an older subdivision by my house. I spotted it during a walk this summer. I just went for a drive to see it for the fall...wow, amazing fall color.

Haven't bought a Ginkgo from these folks, but I've bought other things and have been pleased.
