I bought a Christmas cactus at my department's student club annual holiday plant sale a couple of years ago. When I got it, it had multiple gorgeous fuschia blooms. Then it entered my house and slowly lost them all.
Christmas cacti are trained when to bloom by growers. They need to have light only during the day for something like six weeks before they bloom. Well, mine's in my kitchen, and I definitely don't make sure it's in the dark all night. So it hasn't bloomed since I got it.
Until now! For the past month or so, I've been getting one beautiful bloom at a time. When one dies, another opens up. It's nice to stare at while I do dishes (the plant is above my sink).
