It didn't.
Then, my banana plant grew a flower. A big flower. This flower was nearly two feet across, and almost three feet deep- about the size the banana plant itself was when I got it, a year and a half earlier.
Then we got the house painted. The flower wasn't doing well- turning
brown and droopy. the painters cut the flower off, because it was
getting in their way, and was dripping sweet sticky stuff. The plant
appears to be dying, and has developed straight, deep cracks in a spiral
pattern around its base, as if perhaps it's trying to weaken itself so
it'll fall down in the next windstorm. the upper leaves have been
getting browner, appearing to be getting less and less food from the
plant. I suppose it will die completely soon.
