Does anyone know if Tropica Mango in Arizona, and Just Fruits and Exotics sell the real Authentic Blue Java banana tree, that’s not a Namwah banana tree?

Cause I have Bought a suppose Blue Java Banana tree pup on Tropica Mangos, Etsy store. If the banana tree that I bought from Tropica Mango is not a real Blue Java banana tree can someone tell me if Just Fruits and Exotics in Florida sells the Real Blue Java banana trees? Or of any nurseries that are trustable, and sell the real Blue Java Banana tree in the US that ship them?
