Richard I think the temple banana you got may be Musa spp. Pahari Kela
Musa spp. Pahari Kela (Hill Banana, Virupaksha). Sacred fruit of Virupaksha temple and ceremonies. Pahari means: of the mountain. Hardy to 25 deg-F. Fruit will have large, hard seeds unless male flowers (pollen) removed from plant and vicinity. Taste is more acidic than Chiquita banana, and has higher moisture content in fruit. Very susceptible to Fusarium wilt, import restrictions. Safely propagated by tissue culture.
I think I read this on jack daw's post.
