I guess mine must be abnormal, then. I have only ever had 1 keiki shoot off and that was from bad watering habits, I think. Mine bloom faithfully (here is mine this year
) and they send out new shoots just as faithfully. They get full sun (behind window screen) in south-facing window, summer heat, daily soaking in fertilizer/water and grow very long roots and very long canes
One has two canes each year and the other has three canes.
