Ensete ventricosum is not really hard to find in occident. With its red or mottled red leaves is the main banana tree cultured indoors as ornamental plant, and can be found in most professional gardens. I didn't knew that the root is edible, is very interesting.
Musa velutina is also very ornamental with its minute pink bananas full of seeds. Both species can have >3m long leaves easily. Dwarf forms are more suitable for standard houses
