I’ve always found Galen Burrell’s inter-species work very interesting also. I still have an old Galen Burrell price list (2005) in my files, and would have uploaded it here but I can’t find out how to do that – I think we can only upload pictures and not .doc or .xls files?
I have no idea what happened to Galen’s stock. Maybe Bob Johnson knows?
More breeders are collecting species plants to include them in their hybridizing program. Recently I heard that Peter Waltz is also still into breeding with peonies, and that he is focusing on working with species. It is great that the species are gaining more attention again, it will be more than interesting to see results popping up in future years.
