I recently received my second order from Courtney Hackey, divisions of Cattleya trianaei 'A C Burrage' & C. trianaei coerulea. His plants are fantastic and very reasonably priced. His Cattleya divisions are sent bare root with very little roots. I would not suggest an inexperianced Cattleya grower buying from him. But for the more advanced growers, I highly recommend him as a seller.
I also highly recommend their book: American Cattleyas
Species and Outstanding Clones That Define American Hybridizing
It's a hardback with wonderful color photos that I considered a great read as well.
They have it for the best price and Courtney T. Hackney signs it which for me was a wonderful "bonus"
