Hylocereus undatus, commonly known as Dragon Fruit Cactus, is a fast-growing climbing cactus prized for its dramatic stems, spectacular night-blooming flowers, and exotic edible fruit.

Plant Care

Light
Bright indirect light to several hours of direct sun. A sunny windowsill is ideal.

Watering
Allow the soil to dry between waterings. Water more frequently during active growth and reduce watering during winter.

Temperature
Prefers temperatures between 18–30°C. Protect from frost and prolonged temperatures below 10°C.

Potting
Use a very free-draining mix. At Plant Studio, Savvy Succa is ideal for maintaining healthy roots while preventing excess moisture retention.

Hot Tips
Provide a moss pole, trellis, or support if you'd like the plant to climb. Mature plants can produce enormous fragrant flowers that bloom for a single night. Dragon fruit production requires a mature plant, plenty of light, and often hand pollination when grown indoors.

Pet Friendly
Generally considered non-toxic to cats and dogs.
