Christmas Cactus

The Christmas cactus (Schlumbergera truncata) is a species of epiphytic cactus in the family Cactaceae, native to the coastal mountains of southeastern Brazil, particularly in the state of Rio de Janeiro. It is one of the most widely cultivated ornamental cacti in the world, grown commercially under the names Thanksgiving cactus or Christmas cactus, and is the primary parent species of the numerous hybrid Christmas cacti available in horticulture. In nature, Schlumbergera truncata grows as an epiphyte in humid Atlantic Forest, attached to tree branches in areas receiving abundant rainfall and fog. Its flattened, segmented stems — phylloclades — have distinctive claw-like teeth along their margins, which distinguish it from the more rounded segments of Schlumbergera bridgesii. Flowers are produced at stem tips in autumn and early winter and range from white through pink, red, purple, and orange, adapted for hummingbird pollination. In cultivation, flowering is induced by exposure to long nights and cooler temperatures. The species tolerates a wider range of conditions than its native epiphytic habitat might suggest, explaining its success as a houseplant globally. In its native Brazilian Atlantic Forest, it faces threats from continued deforestation.
