Good evening Gabe,
Did Randy give you any information as to the source of this "cultivar",..?
Some Fei came into the state as part of an IFAS research project. The Fei cultivars did not do well according to the research publication. After the research project was over the cultivars became "neglected"..., so much for responsible research. The Menei did best of the Fei, they were susceptable to nematodes (but so are most banana cultivars grown in the U.S.), maybe some lasted long enough to be TCed.
The "MacKlayi" may be worth growing out just to see what they are.
