Hi:
Just wanted to get a bit more clarified with this species in particular.
When you're looking to buy one of these, apparently everyone seems to use the same photo of the bloom looking it from under it for their advertisements. The thing is that I have seen lots of Balbisiana, but with subspecies this and that....

How can I tell a rear balbisiana from a description?
Also what is the subspecies "King Kong"?

Please let me know.

Thanks,
Carlos
