Here's the first bloom on my second Schlumbergera. The bud progression I reported with the first flower, where they were developing in the order of which ones got the most sun, is no longer true -- this one, 'Caribbean Dancer,' was in the north window, and is ahead of the NOID in the west window. So I guess that's not necessarily how it works, and I no longer have a theory.
I do love this flower, though. Slightly purplish pink and slightly orangish red? And it works, is the crazy part. Who knew?
I'm hoping that at some point there will be several flowers open on this plant simultaneously, so I can get a picture of the whole thing. Two reasons for that: one, I'm betting it will be very pretty, and two, it's actually the only one of my Schlumbergeras that's a full plant, as opposed to just being a couple rooted cuttings, so it's the only one that's presentable at all.
Photos of the third plant's flowers as soon as they open.
