Dragon Fruit, Red (Hylocereus costaricensis)
Dragon fruit, with its vibrant hues and unique appearance, is a delight not just to the palate but also to the eye. One of its lesser-known varieties, the Hylocereus costaricensis, or the Costa Rican pitaya, offers a deeper dive into the diverse world of this exotic fruit. Originating from Central America, particularly from Costa Rica and Nicaragua, this species is distinctive for its striking red flesh, which contrasts beautifully against its pink scaly exterior.
Hylocereus costaricensis belongs to the cacti family and thrives in tropical and subtropical climates. What sets it apart from its relatives, such as the more commonly known Hylocereus undatus which has white flesh, is not only its flesh color but also its richer, sweeter flavor. This makes it a favorite among chefs and food enthusiasts looking to add both color and taste to their dishes.
Growing Hylocereus costaricensis can be an exciting endeavor for gardeners. This cactus is a night bloomer and its flowers are large, fragrant, and only open after dark, often wilting by the morning. This ephemeral blooming adds an element of mystery and allure to its cultivation. Furthermore, the plant is relatively hardy, requiring minimal water once established and thriving in well-draining soil, making it suitable for xeriscaping.
Nutritionally, the Costa Rican pitaya is packed with vitamins, minerals, and antioxidants. It is particularly high in vitamin C, fibers, and B vitamins, supporting better digestion and overall health. The seeds contain omega-3 and omega-6 fatty acids, which are beneficial for heart health.
In recent years, Hylocereus costaricensis has gained popularity not just for its health benefits but also for its versatility in culinary applications. From smoothies and salads to exotic desserts, this dragon fruit variant is making its mark in the culinary world. Its vibrant red juice is also used as a natural food coloring, proving its utility extends beyond taste.
For those intrigued by rare and exotic fruits, Hylocereus costaricensis offers a fascinating glimpse into the diversity of nature's bounty. Its cultivation, nutritional benefits, and culinary versatility make it a worthy addition to the gardens and diets of those seeking a taste of the tropics. Whether you're a gardener, a chef, or simply a lover of exotic fruits, the Costa Rican pitaya is sure to impress with its stunning visuals and delicious flavor.

Description: Known for its white flesh and mild flavor. Produces large night-blooming flowers.
Hylocereus costaricensis (Red Flesh Dragon Fruit):
Fruiting Season: Summer to early fall (typically July to October)
Pollination: Self-fertile, but hand pollination can enhance yield and fruit quality.
Best Pollinators: Benefits from being planted alongside other dragon fruit varieties for cross-pollination.
Planting Zone Range: 10–12
Description: Valued for its deep red flesh and sweet flavor; vigorous grower with striking flowers.
Hylocereus megalanthus (Yellow Dragon Fruit):

Plant Information
| Scientific Name: | Hylocereus costaricensis |
|---|---|
| Family Name: | Cactaceae |
| Common Name(s): | Dragon Fruit |
| Size: | 15–20' tall, ~1' wide (trained/climbing) |
| Plant Type: | Perennial Succulent (cactus vine) |
| Origin/Geographic Distribution: | Originates from Costa Rica and Nicaragua; widely cultivated in other parts of the Americas, Asia, and Israel for its fruit. |
| Native to: | Central America (Costa Rica and Nicaragua) |
| Native range in the USA: | Not native to the U.S.; grown primarily in Florida, California, and Hawaii where climates are suitable. |
| Conservation Status: | Not currently listed as endangered or threatened by major international bodies. |
Cultivation
| Planting: | Requires full sun for optimal growth and should be protected from frosty temperatures. Prefers well-draining soil but needs regular watering so roots stay lightly moist; avoid overwatering to reduce risk of rot/fungus. |
|---|---|
| Sun Exposure: | Full Sun, Part Shade |
| Soil Type: | Mostly sand; very well-drained |
| Soil pH: | 6.1–7.5 (slightly acidic – neutral) |
| Water Requirements: | Moist to slightly dry, well-drained. Drought-tolerant once established, but regular watering in spring/summer supports faster growth. Reduce water in cooler months. Poor drainage can cause root rot and stunting. |
| Fertilizer Requirements: | Every 4–6 weeks during spring/summer; reduce or stop in fall/winter as growth slows. Avoid over-fertilizing (can favor foliage over fruit or damage the plant). |
| Pruning Requirements: | Best after harvest (late fall/early winter). Remove dead/diseased stems, thin overcrowded growth for airflow, and shape for fruit production and easier harvesting. |
| Growth Rate: | Fast under optimal conditions; can add several feet in a single growing season and develops aerial roots for climbing/support. |
| Companion Planting: | Companion planting can enhance ecological health and potentially improve yield and fruit quality. See Companion Planting section below. |
Tolerance and Hardiness
| Drought Tolerance: | Drought-tolerant once established, but consistent moisture supports flowering and fruit development. Mature plants handle short dry periods better than young plants. |
|---|---|
| Frost Tolerance: | 40°F |
| Heat Tolerance: | Up to 125°F (in part shade) |
| Wind Tolerance: | Moderate, but strong winds can break stems/tear tissue and increase water loss—especially when carrying heavy fruit loads. Provide wind protection in exposed sites. |
| Salt Tolerance: | Not salt-tolerant; sensitive to soil salinity and salt spray. |
| USDA Plant Hardiness Zones: | 10–11 |
Flower and Fruit Information
| Fruit Type: | Berry |
|---|---|
| Harvest Time: | May take a few years to begin producing. Mature plants can produce multiple cycles per year; fruits typically develop 30–50 days after flowering. |
| Fruit Description: | Vivid red skin with scales and deep red flesh dotted with small black seeds. |
| Edible Plant: | Yes |
| Edible Parts: |
1. Fruit: Sweet, mildly tart pulp with edible seeds; eaten fresh or used in recipes. 2. Flowers: Large white flowers can be eaten (e.g., salads, tea, cooked dishes) with a mildly sweet flavor. |

Companion Planting
Companion planting with Hylocereus costaricensis (dragon fruit) can support biodiversity, reduce pest pressure, and improve overall garden resilience. Below are practical companions and how to use them.
Legumes (Beans and Peas)
