Valentine's Cactus?

After three years of careful watering (well, most of the time), a bit of fertilizer every now and then, and not much else, my Christmas cactus really came into its own this year. Last year it bloomed with just one flower. This year I came home from the holidays to find it chock-full of beautiful pink flowers. Then, a week or so later, another flower bloomed. I should explain that my plant has two different types of "Christmas cactus" in the same pot. The second type has a much redder and more dramatic bloom. Then, lo and behold, just the other day, I got yet another bloom! Perhaps it should be called a Valentine's cactus or a President's Day cactus?

Actually, it looks like the one that bloomed first is a "Christmas cactus" and the one that bloomed a bit later is a "Thanksgiving cactus" - backwards! The main thing to getting them to flower (besides overall age) is to make sure they're exposed to increasing darkness in the winter (no problem here in Seattle), and I think colder temperatures help too. In some climates this can be achieved by placing the plant outside, but my kitchen windowsill seems to work just fine. My plant was made by taking cuttings from other mature plants - one from a coworker, and the other from (I'm a bit ashamed to admit) the floor of the garden center at Home Depot (I asked if it was ok to take it). Now I guess I just need to add an "Easter cactus" to the mix and I'll be all set!
