When I potted up the seedlings, initially, they were very, very tiny. I hadn't tried potting up Schlumbergera seedlings before, and had no idea whether they'd all transplant fine, or whether I'd see 75% of them die the first week, or what. So, to hedge my bets, I stuck multiple seedlings into the same pot, which has turned out to be overkill, since very, very few of the seedlings ever died.
What this means for seedling no. 024 is that it blooms in two different colors, a nice pinky-peach that TinEye's search says is basically exactly the color of Caucasian infants,1 which plant is the clear winner in that particular pot, and possibly of the flat as a whole. And then there's a dark orange with a white tube, which looks a great deal like number 025 / "Clownfish" but is somehow inferior.
For record-keeping purposes, I'm going with "Safety Vest" for the darker bloom, because, you know, whatever. That's the color it is, it's not the better dark orange so there's no point thinking too much about what to call it.
Coming up with a name for the lighter bloom was tough; going strictly off the TinEye results, most of the obvious names wound up being kinda racist in one way or another.2 Fortunately, the page included a photo of Bryce Canyon, in Utah, which was a pretty good color match, so in the interest of recognizing that babies aren't all the same color, seedling 024 will be "Bryce Canyon" / "Safety Vest." I guess. Unless someone can come up with a baby-related name that doesn't sound racist.
2 I mean, I'm willing to buy a Schlumbergera 'Exotic Dancer,' sure, but S. 'Caucasian Infant' seems a step too far.
