Woah! Very nice! That's quite a few spikes. Those look like some pretty stout pseudobulbs so guessing it's not the hillii type. Hopefully when it gets bigger you can attach a division to one of your client's trees. Take a look at this photo of
a specimen on a tree in Australia. We should be able to see the same thing in every neighborhood here in Los Angeles!
Daenerys, I've seen them sold bare root at shows for around $40-$100 per pseudobulb...depending on the variety. Anything less than $40 is a pretty good deal.
It seems to take forever to grow this orchid to blooming size...maybe 10 years...but with optimal conditions you could probably shorten it to 7 years. Once it gets to be blooming size though then it will start doubling in size...so perhaps OrchidByte's specimen is around 15 years old.
