We have two Dieffenbachias in the conservatory, both variegated. I wrote a post about the larger one in December last year. I’m not quite sure which cultivar it is (the other one is a Leopard lily according to the shop where we bought it).
In December I wrote that Dieffenbachias don’t flower when grown indoors, since that was what I’d read. The problem with such a statement is that it’s hard to verify! It can, however, be falsified, and I’m happy to report that our larger Dieffenbachia did just that around 1 August. (It takes me a while to write these blog posts!)
As you can see, it was a flower in the same style as Spathiphyllum, the venerable Peace Lily: there was a sheath surrounding an inflorescence, although the shape and relative proportions were different from Spathiphyllum.
Here’s a close up of the inflorescence which only began peeking out after a long while.
Until that happened, it wasn’t even clear to me that the strange green tube growing on the plant must be a flower! Green isn’t the first colour I expect in a flower… and in any event, as I wrote, I didn’t think the plant would flower at all.
