Pitaya Dragon Fruit: Nutrition, Health Benefits, and Uses

What Is Pitaya Dragon Fruit?

Pitaya dragon fruit is a tropical fruit known for its distinctive appearance and nutritional benefits. It has multiple names and varieties, each with unique characteristics tied to its botanical background and region of origin.

Botanical Classification and Origins

You’ll find pitaya dragon fruit in the cactus family, primarily classified under two genera: Selenicereus and formerly Hylocereus. Most cultivated types belong to Selenicereus, which was once included in Hylocereus. These cacti are native to southern Mexico and parts of Central America, especially Guatemala, Costa Rica, and El Salvador.

This fruit thrives in tropical and subtropical climates and has been introduced globally, from Southeast Asia to the United States. The plants can climb and flower at night, relying on bats or moths for pollination, which influences fruit development.

Common Names and Varieties

You might hear pitaya called dragon fruit, pitahaya, or strawberry pear depending on the location. “Pitaya” typically refers to fruits of the genus Stenocereus, but dragon fruit is associated with Selenicereus. Both terms are often used interchangeably in markets.

There are three main types of dragon fruit:

• Selenicereus undatus (white flesh with pink skin)
• Selenicereus costaricensis (red flesh with red skin)
• Selenicereus megalanthus (white flesh with yellow skin)

Vietnam is a leading exporter, so you may also see the fruit referred to as “Vietnamese dragon fruit.”

Physical Appearance and Taste

The fruit’s skin has a leathery texture with scale-like spikes, resembling dragon scales, which influenced its common name. Size varies, typically between 150 to 600 grams, though some can exceed 1 kilogram.

Inside, the flesh can be white, red, or yellow with numerous small black seeds, similar in crunch to kiwi seeds. Taste profiles range from mildly sweet to slightly tart depending on the variety. The texture is soft and juicy, making it popular fresh or in beverages.
