UPDATE! I have found Kingdom Bound, all due to this great forum. Thank you!

I would dearly love to add Kingdom Bound this Fall. Do you happen to know where I can purchase a double fan of this Emmerich beauty. I have looked online, but have as far, been unsuccessful.

Have you tried contacting the hybridizer?

Try here.

I grow Kingdom Bound and have extra for sale, so send me a tree-mail if you like. It's a vigorous grower! It's listed in the catalog I'm working on which is not finished yet but should be soon. We are licensed as a nursery and are enjoying a fully rust-free year.

Thank ya'll so much for your help, as I have found Kingdom Bound and it will soon be in my garden. I just knew that someone from this forum would be able to help me and I was correct. Thank you!!
