The Burro Banana (Musa × paradisiaca ‘Burro’ or ‘Orinoco’), also known as the Chunky Banana or Horse Banana, is a robust and versatile banana variety prized for its thick, starchy flesh, tangy-sweet flavor, and adaptability in both sweet and savory dishes. Unlike the sweet Cavendish banana, Burro bananas offer a unique lemony tang when unripe and a creamy sweetness when ripe, making them a favorite in Latin American, Caribbean, and tropical cuisines.
Originating in Southeast Asia and widely cultivated in Central America, this cultivar is a dietary staple for its hearty texture and nutritional value. In this comprehensive guide, we’ll explore the botanical classification, history, native area, identifying characteristics, taste, growth rate, USDA hardiness zones, culinary applications, nutritional value, season availability, and a fun fact about the Burro Banana.
Botanical Classification
The Burro Banana belongs to the following taxonomic classification:
- Kingdom: Plantae
- Phylum: Tracheophyta
- Class: Liliopsida
- Order: Zingiberales
- Family: Musaceae
- Genus: Musa
- Species: × paradisiaca
- Cultivar: ‘Burro’ (synonyms: ‘Orinoco’, ‘Bluggoe’, ‘Horse Banana’)
The Burro Banana is a hybrid of Musa acuminata and Musa balbisiana, classified as Musa × paradisiaca to denote its hybrid origin. It belongs to the ABB genome group, a triploid cultivar with two parts Musa balbisiana and one part Musa acuminata. This genetic makeup contributes to its starchy, firm texture and resilience, similar to plantains but with a sweeter profile when ripe. Burro bananas are sterile, seedless, and propagated vegetatively through suckers or tissue culture, ensuring consistent fruit quality. The name “Burro,” meaning “donkey” in Spanish, reflects its sturdy, workhorse-like nature and chunky shape.
History of the Burro Banana
The Burro Banana’s history begins around 10,000 years ago in Southeast Asia, particularly in Papua New Guinea and the Malay Archipelago, where bananas were domesticated from wild Musa acuminata and Musa balbisiana. Hybrids like Burro, valued for their starchy, versatile fruits, emerged through human selection. By 3,000 BCE, bananas spread to India, Indonesia, and the Philippines, with ABB cultivars like Burro likely cultivated for their dual use in cooking and fresh eating.
Burro bananas reached Central and South America before the Columbian Exchange, likely via Polynesian or trade routes, and were well-established by the 16th century when Spanish and Portuguese explorers documented their cultivation in Mexico, Costa Rica, Colombia, and Venezuela. Known as ‘Orinoco’ in some regions, named after Venezuela’s Orinoco River, Burro bananas became a staple in Latin American and Caribbean diets, used in dishes like fried tostones or boiled sides. In Africa, similar ABB cultivars like ‘Bluggoe’ were introduced via trade, thriving in countries like Nigeria and Ghana.
Unlike the export-focused Cavendish, Burro bananas are primarily grown for local markets due to their shorter shelf life and starchy nature. Major producers include Mexico, Costa Rica, Colombia, Venezuela, Philippines, and Hawaii. In the 20th century, Burro bananas gained traction in North America and Europe as a specialty fruit, often found in ethnic markets. The threat of Tropical Race 4 (TR4), a strain of Panama disease, challenges Burro cultivation, but its resilience and culinary versatility ensure its popularity.
Native Area
Burro Bananas originate from Southeast Asia, specifically the Malay Archipelago, Indonesia, Malaysia, and Papua New Guinea, where wild Musa species thrive in tropical rainforests. However, the cultivar is most closely associated with Central America, particularly Mexico and Costa Rica, where it has been a dietary staple for centuries.
Today, Burro bananas are cultivated in tropical and subtropical regions, including:
- Latin America: Mexico, Costa Rica, Colombia, Venezuela, Ecuador
- Caribbean: Jamaica, Puerto Rico, Dominican Republic
- Asia: Philippines, Thailand, Indonesia
- Oceania: Hawaii, Fiji
- Africa: Nigeria, Ghana, Cameroon (as ‘Bluggoe’)
Identifying Characteristics
- Size and Shape: Burro bananas are medium-sized, typically 5–8 inches long and 1.5–2 inches wide, with a short, thick, and blocky shape, less curved than Cavendish. They grow in clusters called hands (6–12 bananas), forming a bunch weighing 15–30 pounds.
- Skin: The skin is thick, tough, and green when unripe, ripening to a bright yellow with brown or black speckles. Ripe Burro bananas are softer, but the skin remains firmer than Cavendish, requiring a knife when green. The skin is prone to scuffing but protects the flesh well.
- Flesh: The flesh is creamy white to pale yellow, firm, and starchy when unripe, becoming softer and creamier when ripe. It is seedless and has a denser texture than dessert bananas, ideal for cooking.
- Stem: The fruit is attached to a greenish-brown stem within the hand, connecting to the main stalk of the bunch. The stem is removed during processing.
- Aroma: Burro bananas have a mild, starchy aroma when unripe, developing a sweet, lemony scent when ripe, with notes of banana and citrus.
- Plant Characteristics: Burro banana plants are herbaceous perennials, reaching 10–20 feet tall, with large, broad leaves (up to 8 feet long) forming a pseudostem. The rhizome produces suckers for propagation, and the inflorescence emerges after 9–15 months, developing into fruit bunches over 3–6 months. Plants are monocarpic, dying after fruiting, with suckers continuing the cycle. Their sturdy build suits windy conditions.
Taste
- Unripe (Green): Green Burro bananas are starchy, mildly tangy, and savory, with a lemony, potato-like flavor and firm texture. They are typically cooked, as they’re too astringent to eat raw.
- Ripe (Yellow): Ripe Burro bananas are sweet with a tangy edge, balancing creamy banana sweetness with a lemony or citrusy zing. The flavor is less sugary than Cavendish, with a robust, hearty profile.
- Flavor Notes: The flavor includes banana, lemon, apple, and a hint of vanilla when ripe, with earthy, starchy notes when unripe. Cooking enhances their flavor, with frying adding crispness and boiling bringing out sweetness.
- Texture: The texture is firm and starchy when green, becoming creamy and dense when ripe. Cooked Burro bananas range from crisp (fried) to soft (boiled or baked).
- Aftertaste: The aftertaste is sweet-tangy when ripe, with a citrusy linger, or mild and starchy when unripe, depending on preparation.
Growth Rate
- Establishment: Plants grow from suckers or tissue-cultured plantlets, reaching fruiting maturity within 9–15 months in tropical climates. New leaves emerge every 7–10 days, forming a pseudostem.
- Mature Size: Plants reach 10–20 feet tall and 1–2 feet in diameter at the pseudostem, with a spread of 6–12 feet due to large leaves. Their sturdy build suits diverse climates.
- Fruit Production: After 9–15 months, plants produce a single inflorescence, developing into a bunch of 50–150 bananas over 3–6 months. Each plant fruits once, then dies, with suckers continuing the cycle. Commercial plantations harvest every 9–12 months.
- Propagation: Burro bananas are propagated vegetatively, as they are sterile. Suckers are replanted, or tissue culture ensures disease-free stock, maintaining genetic uniformity but increasing disease vulnerability.
USDA Hardiness Zones
- Temperature: Optimal growth occurs at 75–95°F, with fruit production slowing below 60°F. Brief exposure to 28–32°F may damage leaves but not the rhizome, allowing regrowth. Prolonged cold below 20°F can kill the plant.
- Sunlight: Full sun (6–8 hours daily) for vigorous growth and fruit production.
- Soil: Well-drained, fertile soils (pH 5.5–7.0), preferably loamy or sandy loam with high organic matter. Bananas are heavy feeders, requiring nitrogen, potassium, and phosphorus.
- Climate: Tropical and subtropical climates with high humidity (60–80%) and consistent rainfall or irrigation. Wind protection is recommended, though Burro’s sturdy build tolerates moderate winds better than other bananas.
- Adaptability: Burro bananas have slight cold tolerance, surviving light frosts in Zone 8 with protection (e.g., mulching, wrapping). In colder zones, grow in containers and move indoors to a bright, warm space (above 60°F). Their robust nature makes them suitable for diverse growing conditions.

Fun Fact
The Burro Banana, nicknamed the “donkey of bananas” for its sturdy, chunky shape, is a Mexican favorite, often fried into platanos fritos and served with crema at street stalls! In Venezuela, it’s a key ingredient in sancocho, a hearty soup that warms families during rainy seasons. Its tangy flavor inspired a Caribbean saying, “As zesty as a Burro banana,” celebrating its lively taste, and farmers swear Burro plants are so tough they can withstand storms that topple other crops, making them a symbol of resilience!
Care and Cultivation Tips for Burro Banana Plants
- Planting: Plant in spring in a sunny, wind-protected site with fertile, well-drained soil (pH 5.5–7.0). Use suckers or tissue-cultured plantlets from nurseries. Dig a hole 2 feet deep and wide, enrich with compost, and plant with the rhizome base level with the soil. Space plants 10–15 feet apart.
- Watering: Water deeply (1–2 inches daily) to keep soil moist but not waterlogged. Mulch with 4–6 inches of organic material to retain moisture and suppress weeds.
- Fertilization: Apply a high-potassium fertilizer (e.g., 8-10-10) every 1–2 months during the growing season, providing 1–2 pounds per plant. Supplement with compost or manure for organic matter.
- Pruning: Remove dead or damaged leaves and trim suckers to maintain 2–3 suckers per plant for future growth. After fruiting, cut the pseudostem to ground level to encourage new suckers.
- Pest and Disease Control: Monitor for Panama disease (TR4), black sigatoka, and pests like banana weevils or nematodes. Use resistant stock, practice crop rotation, and apply fungicides or neem oil as needed. Remove infected plant material promptly.
- Support: Prop heavy fruit bunches with bamboo poles to prevent toppling. Cover bunches with plastic bags to protect from pests and improve fruit quality.
- Winter Protection: In Zone 8, mulch heavily (6–12 inches) and wrap pseudostems with burlap or frost cloth during cold snaps. In colder zones, grow in containers and move indoors to a bright, warm space (above 60°F). Burro’s resilience suits diverse conditions.
Challenges and Considerations
- Limited Availability: Burro bananas are rare outside tropical regions, requiring ethnic markets or home cultivation.
- Disease Vulnerability: Susceptibility to Panama disease (TR4) threatens production, with no resistant Burro clones widely available.
- Cold Sensitivity: While slightly cold-tolerant, prolonged cold below 28°F damages plants, limiting outdoor cultivation to warm zones.
- Short Shelf Life: Green Burros last longer, but ripe ones spoil quickly, requiring timely use or preservation.
- Culinary Preparation: Green Burros require cooking, which may deter those unfamiliar with their starchy nature.
