🌵 Schlumbergera truncata
Schlumbergera truncata, commonly called the Thanksgiving cactus, is a popular flowering houseplant known for its bright, tubular blooms that appear in late fall.
🌸 Key features
- Flowers: Pink, red, white, orange, or purple
- Bloom time: Usually around November (hence “Thanksgiving cactus”)
- Stems: Flat, segmented, with pointed “teeth” along the edges
- Origin: Native to Brazilian rainforests (it grows on trees, not in desert sand!)
🌿 How it’s different from Christmas cactus
People often confuse it with its cousin, the Christmas cactus:
- S. truncata: sharp, claw-like edges + blooms earlier
- Christmas cactus: rounded edges + blooms closer to December
🪴 Care guide
Light
- Bright, indirect light (avoid strong midday sun)
Water
- Keep soil lightly moist
- Let the top layer dry slightly between watering
Soil
- Well-draining mix (like cactus soil + some organic matter)
Temperature
- Prefers 15–24°C
- Needs cooler nights to trigger blooming
🌺 How to encourage blooming
- Give long nights (12–14 hours of darkness) for a few weeks
- Keep in a slightly cooler spot
- Avoid moving it once buds form (they can drop!)
⚠️ Common issues
- Bud drop → caused by sudden changes in temperature or light
- Overwatering → can lead to root rot
- No flowers → not enough darkness or too much heat
