Christmas Cactus
Schlumbergera × buckleyi
Christmas cactus (Schlumbergera × buckleyi) is considered non-toxic to cats. Published toxicity information for this exact hybrid is limited, so this is not a guarantee of harmlessness. Keep it for decoration, rather than for your cat to eat.
Non-toxic does not mean edible. Eating plant material can still upset your cat’s stomach.
What this guide covers: This guide covers Schlumbergera × buckleyi, the Christmas-cactus hybrid. Other holiday cacti require their own identification.

How to grow this plant
Container growing guidance for Schlumbergera × buckleyi.
- Light
- Bright indirect light
Provide bright, indirect light. This is a forest cactus, rather than a desert plant for baking sun.
- Watering
- Keep evenly moist
Keep the mix evenly moist during active growth, but avoid a persistently wet root zone.
- Temperature
- Active growth: 70–80°F / 21–27°C
For bud formation, nights around 55-65°F (13-18°C) and about 13 hours of darkness are useful. This is a seasonal treatment, not the normal growing range.
- Humidity
- Higher humidity
Prefers humid air.
- Potting
- Use an airy, well-drained mix.
- Through the year
- For autumn bud formation, provide long uninterrupted nights and cooler conditions; water less after flowering. Once buds develop, avoid drafts and abrupt changes in temperature, humidity or watering that can cause bud drop.

Listed by the source as Epiphyllum x buckleyi. The veterinary entry explicitly includes the basionym Epiphyllum x buckleyi and the same parent cross. Kew lists Epiphyllum × buckleyi as the homotypic synonym. ASCII x and × denote the hybrid marker here; this does not map Schlumbergera bridgesii or truncata to this hybrid.
