Well, i thought I'd post for once. The Schlumbergera truncata bloomed in January, the Rhipsalidopsis gaertneri are in bloom right now. Rhipsalidopsis gaertneri was formerly Hatiora gaertneri but was removed from Hatiora and now included in Schlumbergera from recent phylogenetic studies, but an alternate taxonomy approach considers them separate in the genus Rhipsalidopsis with two species, gaertneri and rosea. There are noticable differences in the genera including different flower symmetry and the fact they close at night, (Schlumbergera don't) as well as foliar differences. Rhipsalidopsis have softer rounder stems with no points and have more "spines". I like to keep them separate because they are visually different but the care is pretty much the same however Rhipsalidopsis are less hardy/forgiving ime. Please know these are epiphytic rainforest cacti so their requirements are different from arid desert cacti. In order, Rhipsalidopsis gaertneri cv pink, red, magenta, Schlumbergera truncata cv magenta, peach/salmon. Note the differences in the flowers, and the pointy leaves of S. truncata.
