Christmas Cactus Saturday
All the brightly colored Christmas Cactus are out, and not a day too soon.
These are all hybrids from Brazilian species. Nobody knows anymore what the original species from the jungles were, but we like to think they are hybridized from Schlumbergera orsicchiana, which tend to be pendant and epiphytic.
All those green segments that look like leaves are really stem segments, and the cactus spines, as these are true cacti, come from the joints between the segments. The segmenting of the stems makes for easy cuttings.
Some would call these hybrids something along the lines of Schlumbergera orssichiana x truncata, but the truncata part of that was long ago gathered into Zygocactus, but then put back into Schlumbergera in 1967. So if you see these advertised as Zygocactus you should know that they are archaically sticking to the early 60s. Old people today.
