Kale.

This is a kale, or cabbage flower, given to me by Denise a couple of months ago. Some people don't like cabbage flowers, but I think they are kind of striking and the colours are vintage looking. It never died, and in fact it's grown roots and looks like it is going to seed. I'm keeping it as a houseplant. It is almost zero maintenance - it drops a dead leaf occasionally, but seems to thrive with old stale water and little light.
