Thank you Karen and Pomtzu.

I had one in a West-facing window where I worked, and it blossomed every year from about Halloween to Easter!
If west is better they will go to my office. Now I need a good heavy kitty-proof pot as the two youngters daredevils like to "clean" it.

And you can start new plants by breaking off a branch (3 or 4 leaves long), and just putting that in a cup of water so that the bottom leaf only is in the water. When you see roots sprouting on the bottom, then just plant it in a good potting soil, and you have a new plant started!
I have tried this method to grow other stuff like turnip greens for Magda the Iggy but the water always get rotten and I've never succed.

Glad they are not poisonous to cat though!
