Dragon Fruit Cactus (Hylocereus undatus): Night-Blooming Beauty & Edible Fruit

Overview

Dragon Fruit, or Pitaya (Hylocereus undatus), is a vining, epiphytic cactus famous for its spectacular nocturnal flowers and vibrant pink-skinned, white-fleshed fruit. The stems are three-ribbed, green, and can climb 20+ feet using aerial roots. Fragrant, dinner-plate-sized white blooms open at night, attracting bats and moths. The resulting fruit is sweet, refreshing, and rich in antioxidants. A fast grower, it's ideal for trellises, arbors, or hanging baskets in frost-free climates.

Key Features

• Stems: Triangular, segmented, spineless or with tiny spines; photosynthetic.
• Flowers: Huge (10–12 in), fragrant, white with yellow centers; bloom summer nights.
• Fruit: Oval, bright pink skin with green scales; white flesh with tiny black seeds.
• Growth: Vigorous climber; needs strong support.
