Morrito (Crescentia alata): The Fascinating Calabash Tree for Tropical Gardens
If you’ve ever wondered about those enormous, round fruits hanging from trees in tropical landscapes, you might have been looking at a morrito tree. Known botanically as Crescentia alata, this unique species brings both beauty and intrigue to warm-climate gardens with its spectacular calabash fruits and night-blooming flowers.





What Makes Morrito Special?
The morrito is a perennial tree that typically grows as a single-trunked specimen reaching heights of 13-16 feet or more. What really sets this tree apart are its impressive fruits – large, round calabashes that can measure 6-10 inches in diameter. These hard-shelled fruits have been traditionally used for crafting bowls, containers, and musical instruments, making the morrito both an ornamental and culturally significant plant.
The tree produces white, nocturnal flowers that open at night, creating an enchanting evening display while attracting bats and night-flying insects for pollination. During the day, the broad canopy of large, simple leaves provides welcome shade in hot climates.
Native Status and Distribution
While morrito naturalizes and reproduces in Puerto Rico, it’s actually a non-native species that has been introduced to the region. The tree’s original range spans Central America and northern South America. In Puerto Rico, it has established itself and persists in the wild without human intervention.
Is Morrito Right for Your Garden?
Morrito can be an excellent choice for gardeners in tropical and subtropical regions, but there are some important considerations:
- Climate requirements: This tree needs consistently warm temperatures and is only suitable for USDA hardiness zones 10-12
- Space needs: With its broad canopy and large fruits, morrito requires ample space
- Unique appeal: Perfect for gardeners who want something truly distinctive
- Cultural interest: Great for ethnobotanical gardens or collections
Since morrito isn’t native to many areas where it’s grown, consider exploring native alternatives that provide similar benefits to local ecosystems while still offering ornamental value.
Growing Conditions and Care
Morrito thrives in warm, tropical to subtropical climates and appreciates:
- Sunlight: Full sun to partial shade
- Soil: Well-draining soil (specific soil preferences need further research)
- Water: Regular watering during establishment, then moderate water needs
- Temperature: Frost-sensitive, requires year-round warmth
Planting and Care Tips
When planting morrito, choose a location with plenty of room for the tree to spread. The large fruits can be quite heavy, so avoid planting near structures or walkways where falling fruit might cause damage. Protect young trees from strong winds, which can be problematic due to the weight of mature fruits.
Minimal pruning is typically required, though you may want to remove any damaged or crossing branches. Regular watering during the establishment period will help your morrito get off to a strong start.
Wildlife and Pollinator Benefits
The morrito’s nocturnal flowers attract bats and night-flying insects, making it a valuable plant for nighttime pollinators. However, the specific wildlife benefits for birds and other creatures would benefit from additional research.
The Bottom Line
Morrito is a conversation-starter tree that brings tropical flair and cultural significance to warm-climate gardens. While it’s not native to many areas where it’s cultivated, it can be a fascinating addition for gardeners who have the space and climate to support it. Just remember to research native alternatives that might provide similar aesthetic appeal while supporting local ecosystems more effectively.
If you’re drawn to unique, fruit-bearing trees and live in a tropical zone, morrito might just be the distinctive specimen tree your landscape has been waiting for.
