Description
Schlumbergera opuntioides is a rare cactus with green leafless stems made up of distinct segments. The stems look like those of an Opuntia. Young segments may be relatively flat, up to 2.8 inches (7 cm) long, up to 1.2 inches (3 cm) wide, and up to 0.4 inches (1 cm) thick. They become more cylinder-shaped as they age, as well as becoming woodier. The plant may form a shrub up to 4 feet (1.2 m) tall. Flowers are pink to purple, up to 2.4 inches (6 cm) long, and up to 1.8 inches (4.5 cm) in diameter.

Hardiness
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).
How to Grow and Care
These plants are easy to grow and are often passed down through the generations. With Holiday Cactus, the million-dollar question isn't how to grow it but how to make it bloom. With a little extra attention during the fall months, you can have your plants blooming for the holidays. Don't expose these plants to freezing temperatures! Despite their love of cooler temperatures, they are still tropical plants that won't withstand freezing conditions. They like about 50% to 60% humidity, which can be achieved using a pebble tray. Never place your Holiday Cactus near a heat register, exterior door, or drafty window, and keep it out of burning sunlight.
Don't fall into the trap of constantly repotting into a bigger pot. Holiday Cactus likes to be root-bound, and repotting every 2 to 3 years (even back into the same pot) is plenty. If you repot, use sterile, well-draining potting soil.
Holiday Cactus can easily be propagated by cuttings. First, pinch off a section of stem that has 2 to 3 jointed segments. Let the cuttings dry for a few hours, then push them in a small pot with the same potting soil as the adult plant.
