Aki, go for it. As long as you can handle resisting watering when it's not growing, and are willing to water it madly when it is growing, they are weeds! Mine lives in my livingroom. I've had it just over a year. I had to withdraw water to get it to go dormant, and did spray a bit in the winter as it's dry in there with the central heating on. It's now growing strongly again.
Bellini: looks good! Is this first flowering? How big is the plant?
