I have had this rather neglected Christmas cactus for years. (So mistreated, in fact, that I call it a Christmas cactus when clearly it is a Thanksgiving cactus—a close relative of the Christmas cactus. This one, with its clawed leaves, is Schlumbergera truncata, while Schlumbergera bridgesii, the Christmas cactus, has notched—rather than pointed—leaf edges.)
It’s been in the same pot for more than a decade, and I give it only the most minimal fertilizer when I’m feeding the rest of my indoor plants during the summer months. Despite that, it that has decided to produce two blooms for me—in two different colours, no less! Just to be clear, this is the same plant producing blooms of different colours. Has anyone encountered this before? I’m not troubled by it – just curious as to why. Is this an example of reversion?
