Gday Matt
Thanks for putting up the video. There are some Dragon Fruit grown here in Oz, but i doubt that there is the same range of varieties you have in the US.
I was thinking of putting in a few this year just to see how they went. I have a plant which I was going to propagate, but I have no idea what variety it is.
The video mentioned that hand pollination is practised, and that insects such as bees can also play a major role in pollination. I was wondering that if the plant flowers at night, has a strong perfume and white blooms (classic attractors for nocturnal pollinators) - whether moths (or perhaps some other nocturnal animal) were originally involved in its pollination biology.
cheers
