Do Dieffenbachia bloom? I have one (of many, I have been growing them for 35 years) and it looks like it is about to bloom. There are no outward signs of insects but one large 'something' like a leaf attempting to open that is swollen and NOT opened now for two weeks. There is one other small leaf that is partly open but one side has not fully uncurled. Have you ever encountered this?

The dieffenbachia may bloom with a flower that looks much like a calla lily. The problem is that the plant will usually die once it is finished blooming. However, by the time a dieffenbachia is ready to bloom, it will almost always have new side shoots growing from it, which you can take to grow a new plant. Keep in mind that flowering is also a rare event when grown as houseplants, so if you get one to bloom, consider yourself lucky!
