Going Bananas in Homestead lists Hua Moa as available from them.
Just FWIW, I grew it once and it was highly cold sensitive here in zone 9b, which I learned the hard way.
One alternative maybe, would be to visit one of the Latino supermarkets near you to ask if they have a banana called 'Hawaiana', which is the name of Hua Moa in spanish. (The Cubans like to use 'Hawaiana' to make fried plantains.) I found it easier to just buy the fruit instead of trying to keep that cultivar alive and happy.
Cheers!
