We’re always on the search for new bananas that will be winter hardy without protection in our Zone 7b winters, and two that have looked great so far are the South Asian native Musa balbisiana (Northeast India to South China) and the Northeast Indian native Musa nagensium var. hongii. If these continue to thrive, we will propagate these so we can share.
Have you had Musa nagensium var hongii flower? I think its a mainly red, multicolored thing?
No flowers yet.
