Summary

Selenicereus undatus, commonly known as white-fleshed pitahaya or dragon fruit, is a climbing cactus native to tropical forest regions in Central America and Mexico, where it grows in rocky areas and trees as an epiphyte. It is a fast-growing, perennial vine that can reach lengths of several meters. The stems are fleshy, three-angled, and possess aerial roots that allow the plant to climb and secure itself to supports.

The dragon fruit is celebrated for its large, fragrant, nocturnal flowers, which bloom from summer to early autumn. These impressive blooms are among the largest in the cactus family, measuring up to 30 cm (11.8 in) long, and are typically greenish-yellow or whitish, occasionally with a rose tinge. Following pollination, the plant produces oblong to oval fruits, 6 to 12 cm (2.4 to 4.7 in) long, with a distinctive leathery skin covered in scales. The flesh inside is sweet and white, containing numerous small black seeds. In cultivation, Selenicereus undatus is valued for its ornamental appearance and its delicious fruit, which is high in fiber and vitamin C. It is commonly grown in tropical and subtropical gardens as an ornamental vine, often on trellises or against walls, and is also commercially cultivated for its fruit. This cactus prefers well-draining soil, high humidity, and partial to full sunlight. It requires regular watering during the growing season but should be kept drier in winter to prevent root rot. While generally pest-resistant, it can be susceptible to scale insects and mealybugs.

Gardeners should be aware that Selenicereus undatus can become invasive in some regions, so it is important to check local guidelines before planting. It is also sensitive to frost and needs protection in cooler climates.CC BY-SA 4.0
