The holiday cactus wars

Schlumberera truncata 04
What’s blooming on the windowsill at Fuchsias in the City this Thanksgiving? Schlumbergera truncata.

Schlumbergera truncata (and its modern hybrids like mine) is commonly called a Thanksgiving cactus in the US since it starts to bloom just before that quintessential American holiday in November. Americans do quibble that this is NOT a Christmas cactus (Schlumbergera x buckleyi. syn. Schlumbergera bridgesii)—It’s a Thanksgiving cactus.

Elsewhere in Thanksgiving-free areas of the world, though, it might actually be referred to as a Christmas cactus. Or to bridge the divide, a false Christmas cactus. The second sounds too much like the Krampus will get you if you've not been good little boys and girls.

If we're looking for other sensible common names, calling it a November cactus won't work out as it starts to flower in May in its native habitats in the Southern Hemisphere. In Brazil, Schlembergera is even called the Flor de Maio, or the May flower. That would certainly be confused with the ship that brought the Pilgrims to Plymouth Plantation for the first Thanksgiving in America, though.

Maybe it'd be better to refer to it as an early holiday cactus. After all, St. Nicholas really does show up late on December 5, or St. Nicholas' Eve, to make a festive splash with goodies or coals on the morning of December 6. That's the real date of good ol' St. Nick's feast. That Santa-Claus-on-Christmas-Eve thing got very confused after the British took New Amsterdam over from the Dutch and then the Americans later absconded with Sinterklaas as well.

There's also another less-appealing common name of crab or crab claw cactus due to its crabby leaves. Which I really do find a less appealing description. It's that Krampus thing again.

To be honest even botanists have had a hard time with Schlumbergera truncata. It amassed a zillion synonyms—Cactus, Cereus, Epiphyllanthus, Epiphyllum, Hatiora, Opuntiopsis, Rhipsalidopsis, Zygocactus, Zygocereus—as it wandered through almost the whole of the botanical alphabet. Thankfully the Easter cactus (formerly Hatiora but now Schlumbergera gaertneri as well) isn’t quite as controversial in its common name. In the Northern Hemisphere anyway.

In the end, as in the beginning, I’ll probably stick with Schlumbergera truncata.

Oh, the vagaries of plant names, common or otherwise.

Happy Thanksgiving, though!
