Scientific Name: Schlumbergera truncata Schlumberger's cut off cactus Caribbean Dancer. Common Name: Christmas Cactus, Thanksgiving Cactus, Holiday Cactus, Crab Cactus, Claw Cactus. Origin: Native to coastal regions of Brazil. Description: Named for the season in which it flowers, the Christmas Cactus will add a splash of colour to your home even while the leaves outside are brown and falling. The bright white flowers of our cacti stands out against their bright green stems. Its stems, truncated (as in its scientific name) into sections of spiky-looking foliage, sprout out from the centre of the pot in an explosion of foliage. Unlike other cacti, they prefer indirect light and humid air, but are still easygoing- and like other succulents, don't like to be too soggy! The christmas cactus will repay your care with bright blooms and bushy foliage.
