Best species banana for cool summer temperatures?
I'm looking for people experiences with wild bananas growth at low temps. There is numerous threads about cold hardiness which are great but I am specifically seeking information on growth in cool temperatures. My climate is relatively mild as a zone 9b however even during the summer months the temps rarely go over 80 degrees Fahrenheit and consistently drop into the 50's at night. So I am looking for wild bananas that grow vigorously at low temperatures? All experience welcome!!
