A Flower of Rarest Bloom

In the ten years since I received a Dieffenbachia maculata, I have never once seen my original plant nor any of its offspring bloom... until now. I wish I knew what inspired this particular plant to do what neither it nor its ancestors before it have done (at least not in this home). Maybe it wanted attention? Maybe the celestial soils aligned properly? Maybe it thinks it's dying? Maybe I'll never know. But I hope I don't have to wait ten years to see this again!
