Manzano is one of the best tasting bananas. However, I am probably a bit bias since I grew up eating it as a kid. They lose their leaves at about 32 degrees. That is not a killer for them, though, because the trunk can survive a short duration freeze (a couple hours in the high to mid 20s) and still push new leaves and a bloom when the weather gets warm again. If you plant to grow one out doors in Tennissee its gona need som major cold protection. I am open to hear about how people accomplish that or anout more cold hardy bananas that I have never grown personally like Basjoo. I have not personally grown Saba or Praying Hands, but I have seen them around town. They are huge plants compared to Manzano. Saba in particular. I don't think they have noticibly more cold hardiness than what I mentioned with Manzano--maybe a degree or two.
