It looks like you may be referring to Dragon Fruit (also known as pitaya). If you actually meant “Deagon fruit” as a different plant, let me know and I will correct it — but since “Deagon fruit” doesn’t correspond to any known species, here is the description of the Dragon Fruit plant:

🌵 Dragon Fruit (Pitaya) – Plant Description
Botanical Name:

Hylocereus spp. (also Selenicereus spp.)

Family:

Cactaceae (Cactus family)

Growth Habit:

Dragon fruit is a climbing, vining cactus.

It grows upright but needs support structures (trellis, posts, or walls) because its stems are sprawling and heavy.

Mature plants can reach 10–20 feet (3–6 m) tall when supported.

Stems:

Bright green, three-ribbed, succulent stems with wavy, scalloped edges.

Stems can grow several meters long.

Along the ribs are small, soft spines (very different from typical desert cactus spines).

Flowers:

Large, showy, and fragrant.

Often called “moonflowers” because they bloom at night and wilt by morning.

White or pale yellow, typically 8–12 inches long.

Fruit:

Oval to oblong, usually 3–5 inches long.

Exterior skin is brightly colored:

Pink/red with green scales (most common)

Yellow (yellow pitaya)

Interior pulp can be:

White, red, or magenta, depending on cultivar.

Contains numerous tiny, edible black seeds.

Texture similar to kiwi; flavor mildly sweet, sometimes floral.

Climate & Growing Conditions:

Thrives in tropical and subtropical climates.

Prefers full sun (at least 6–8 hrs/day).

Requires well-drained soil; sensitive to waterlogging.

Drought-tolerant but fruits best with consistent watering.

Uses:

Eaten fresh, added to smoothies, desserts, salads, drinks.

Some varieties used ornamentally for their striking flowers.
