On the one hand ... Christmas cactus is said to be capable of living a very long life. It's easily propagated and good grief, what a bloomer!
But oh dear. Just when I decide I must have one, I read about it ... and the bloom is off very quickly. This things sounds ridiculously fussy! Of course - it's a tropical plant trying to adapt to a cold winter up North.
It needs just the right light and a regular watering schedule, but the schedule's different in fall and winter. Good luck with that if you have anything remotely like a typical existence in 2011. And it needs just the right humidity.
Even if you do all these things, and the plant buds up, the buds can fall off.
