I bought a banana tree in August of 2021 and never thought it would actually fruit. I was walking by it the other night and saw something purple/maroon out of the corner of my eye. Popped my head between some leaves and was greeted by some baby bananas!
I live in Idaho. It became big enough that it was annoying getting it outside in the summers so it has been living indoors exclusively for the past 2-ish years
