Thanksgiving Cactus is a member of the Cactaceae family. Schlumbergera truncata is the parent of many hybrid SchlumbergerasIn its native habitat, this rain forest cactus is epiphytic, making its home on trees.

Flat stem segments are long and narrow and connected by a mid-rib. Its deeply indented stems look like crab claws, giving it a second common name, Crab Cactus.

In late fall, this tropical cactus bears big, beautiful flowers, which may be red, pink, peach, orange, white, or bicolored.

Many cultivars are available to choose from. The names are almost as tempting as their spectacular blooms. Here are just a few...

'Peach Parfait' and 'Twilight Tangerine' have peach and orange blossoms, respectively...'Red Radiance' is dark crimson...'Majestic' is purple.

Pruning Tip:

Cut the stem off between segments (the place where they're joined together by a midrib). Use sharp, clean pruning shears to prevent tearing the stems.

You'll get a fuller plant by pruning. Cutting it back in spring will encourage the plant to branch out where the stem was cut. Flowers emerge from the ends of the stems so you'll get more blooms this way. Spring is the best time to prune it back, when it begins actively growing again.

How to get the blooms. Flowering results from shorter, cooler days for 8-10 weeks. Putting your cactus outdoors in early fall is ideal. Be sure it's in a shaded location. Bring it back inside before the first frost. Once buds set, don't move the plant around. Flower buds are likely to drop off if the plant is moved or suddenly exposed to temperature changes. If this happens, don't worry. It will bloom beautifully next year.
