This flat-segmented, spineless plant looks nothing like our image of a cactus, yet it is one. The segments have rounded to toothed margins and bear hanging flowers in red, pink, white, or yellow in fall and winter.
Cool, dry conditions in the fall months coupled with short days stimulate blooming. Moving the plant when its buds are small will cause them to fall off. The Christmas cactus blooms more heavily with time than when first purchased.
