Hello, I hope this is not too late for you.
You can contact Water Orchds (Ms Hope Sun) in Taiwan. theIR web site is: WWW.WATERORCHIDCOM.
I just bought few of these plants from them at the Fort lauderdale + Tamiami Orchid shows two weeks ago. I live in s.florida (zone 10). They are sold out like "Hot cakes" in two shows - Big and georgous flowers. Good luck
