Thanks,
I will be watching for an answer!

Most of us on GoY are UK based Tammyrima, you could trying doing a Google search and see what comes up or send a private message to Tugbrethil.

Hmm...I don't exactly know where to find the species, either. I would first try to contact the local branch of the American Rose Society, and see if any of their members have cuttings or seedlings for sale. Various rose growers that specialize in "old roses" may be able to help, too.
