Schlumbergera truncata aka Christmas Cactus

Taxonomy

Schlumbergera truncata, also known as the false Christmas cactus or crab's claw cactus, is a species of plant in the family Cactaceae. It is endemic to a small area of the coastal mountains of southeastern Brazil, where its natural habitats are subtropical or tropical moist forests. Christmas cactus Schlumbergera truncata grows up to 30 cm tall before weeping and 30-45 cm in diameter, with arching, pendulous branches from whose tips hang satiny, zygomorphic flowers that range in colour from red to pink, purple, orange, white or multicolour, with yellow pollen, white filaments, and terete ovaries. Although these plants in the Schlumbergera genus are leafless and use modified stems to capture sunlight instead of leaves, they bloom in the late autumn or winter unlike the Easter cactus. In the wild, they are epiphytes, meaning they grow on tree branches or rocks.

Christmas Cactus, Thanksgiving Cactus, Claw Cactus

How to care for Christmas Cactus

Difficulty

Even if you don't have a green thumb, you can successfully care for Christmas Cactus due to its easy-going nature.

Water

Christmas Cactus does best in dry soil and should only be watered sparingly.

Soil

To ensure the health of your Christmas Cactus, it's crucial to use a potting soil that won't hold too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and organic matter for nutrition is ideal. Adding a few handfuls of perlite to store-bought cactus soil is an easy way to create this type of soil mix.

Lighting

To ensure optimal growth, the Christmas Cactus prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the wintertime, it's common for Christmas Cactus to go dormant and their growth may slow down, so waterings should be spaced out more.
