I'm not sure about the board rules on that.
I had a big specimen of Dendrobium Warawan but I got rid of it last year due to the size of the plant, but they are great in that they grow and bloom with ease and the bloom lasted me about 7 months on end!
If you ever visit a big nursery where they have lots of dendrobium hybrids, you will see it mixed in the collection.
Also, if you have Trader Joes in your area, visit the store often. You might see them although all the dendrobium warawan I saw at my TJ were of inferior quality.
There is also a member here who lives in Southern Cali who bought one from his TJ.
Maybe when his plant gets big enough to be divided or make keikis, you could get one?
The nearest TJ is four hours away in Albuqueque. Not someplace I visit very often.
