The ceiba tree is one of the most remarkable trees on earth. It grows to over 70 metres in height, produces a trunk covered in conical spines, and supports an ecosystem of hundreds of species from root to canopy. It was sacred to the Maya, who believed it connected the underworld, the earth, and the heavens. It is the national tree of Guatemala and Puerto Rico. And in tropical forests across Central America, South America, West Africa, and Southeast Asia, it is a keystone species, one whose presence supports the survival of dozens of other organisms.
Key Takeaways
- The ceiba tree (Ceiba pentandra) is one of the tallest tropical trees in the world, reaching 70+ metres, with a trunk up to 3 metres in diameter covered in conical spines.
- It is the national tree of Guatemala and Puerto Rico, and was the sacred world tree of the ancient Maya civilisation.
- The ceiba is a keystone species, its flowers feed bats and insects, its hollow trunk shelters wildlife, and its kapok fibre was historically used for life preservers and insulation.
- Ceiba trees are found across tropical regions of the Americas, West Africa, and Southeast Asia, typically in lowland tropical forest at elevations below 1,000 metres.
What Is the Ceiba Tree?
The ceiba tree, Ceiba pentandra, belongs to the Malvaceae family (the same family as cotton and hibiscus). It is also known as the kapok tree, silk cotton tree, or simply kapok, a reference to the fluffy white fibre that surrounds its seeds and was historically harvested for stuffing life jackets, mattresses, and insulation.
The ceiba is one of the largest flowering plants in the world. In optimal conditions, a mature ceiba can reach 70 metres tall with a crown spread of 30 metres or more. The trunk is typically swollen at the base, with large buttress roots extending several metres outward to anchor the enormous structure. In younger trees, the bark is covered in large conical spines, these deter bark damage from climbing animals. In older trees, the trunk becomes smooth and grey.
The Ceiba Tree in Maya Culture
For the ancient Maya, the ceiba was the sacred world tree, Yaxche, the “first tree,” the axis mundi that connected the thirteen layers of heaven above, the earth below, and the nine levels of the underworld. Its roots reached into Xibalba, the Maya underworld. Its trunk stood in the earthly plane. Its canopy touched the celestial realm.
This cosmological significance made the ceiba untouchable in many Maya communities. Cutting a ceiba was believed to bring serious misfortune. The tree was planted at the centre of villages and at the four cardinal points of ceremonial spaces. Many Maya communities in southern Mexico and Guatemala maintain ceiba trees in prominent locations today, and the cultural reverence for the species remains strong.
The Spanish colonisers observed this practice and reported it extensively. The Maya association of the ceiba with the concept of the world tree connects to similar cosmologies across Mesoamerican cultures.
Ceiba Tree Characteristics
- Height: 25-70 metres at maturity. Among the tallest tropical trees in the world.
- Trunk diameter: 1-3 metres. Buttress roots can extend 5+ metres from the base.
- Bark: Covered in conical spines in youth; smooth and grey-green in maturity.
- Leaves: Palmate, with 5-9 leaflets. The tree is briefly deciduous in drier seasons.
- Flowers: White to pinkish, opening at night, pollinated primarily by bats and moths. Bloom lasts only a few days but occurs in spectacular profusion.
- Fruit: Woody pods, 7-15cm long, containing up to 200 seeds surrounded by kapok fibre.
- Lifespan: 200-300 years in undisturbed forest. Some specimens are estimated to be much older.
Where Does the Ceiba Tree Grow?
The ceiba is native to tropical regions of the Americas from Mexico through Central America and into South America. It was introduced to West Africa and Southeast Asia, where it now grows extensively in countries including Ghana, Nigeria, Indonesia, and the Philippines, so early in the colonial period that its status in many of these regions has been debated.
The tree prefers humid lowland tropical forest with rainfall of 1,000-2,500mm per year. It tolerates poor soils but grows most vigorously in deep, well-drained alluvial soils along rivers and in forest gaps where light penetration is good. It is a fast grower in early life, capable of 4+ metres of growth per year in optimal conditions, before slowing as it reaches maturity.
Ceiba Tree as a Keystone Species
A keystone species is one whose presence or absence has a disproportionate effect on the wider ecosystem. The ceiba qualifies for several reasons:
- Bat pollination. Ceiba flowers produce large quantities of nectar and open at night, making them a critical food source for fruit bats and nectar-feeding bats. These bats in turn pollinate the ceiba and many other plant species.
- Wildlife habitat. The hollow trunks of mature ceibas shelter harpy eagles, large owls, bats, and various mammals. The canopy hosts troops of howler monkeys and spider monkeys in Central American forests.
- Insect diversity. The flowers support hundreds of insect species, and the bark supports specialist beetle communities found nowhere else.
- Shade and microclimate. The massive crown of a mature ceiba creates a microclimate, cooler, more humid, that supports the survival of shade-dependent understorey species across a large radius.
Kapok Fibre, What the Ceiba Is Known For
The white, silky fibre that surrounds ceiba seeds, kapok, is extremely lightweight, water-resistant, and buoyant. Before the development of synthetic fibres, kapok was the primary filling material for life jackets, sleeping bags, and upholstery. A single mature ceiba can produce 1,000+ fruits per season, yielding several kilograms of kapok fibre.
Kapok production has declined significantly since synthetic alternatives became available in the mid-20th century. However, interest in kapok as a sustainable natural insulator has revived, and it is now used in some premium sleeping bags, pillows, and acoustic insulation products.
The Ceiba as a National Symbol
Guatemala: The ceiba is the national tree, and its image appears on the Guatemalan coat of arms. The tree represents the Maya heritage of the country and the connection between humanity and nature central to indigenous Guatemalan culture.
Puerto Rico: Also the national tree, known locally as the “ceiba” or “kapok.” Puerto Rico’s landscape was once heavily forested with ceiba trees, and the species holds deep cultural significance.
Equatorial Guinea: The ceiba appears on the national flag, one of very few countries to feature a specific tree species on its national flag.
ForestNation and Tropical Reforestation
ForestNation plants trees in Tanzania, where species selection is tailored to specific degraded sites, including native species with similar keystone roles to the ceiba in the East African context. Every tree is field-monitored for survival and CO2 sequestration. For planting a tree in someone’s name: plant a tree gift.

Frequently Asked Questions
What is special about the ceiba tree?
The ceiba tree is one of the world’s tallest tropical trees (up to 70 metres), a keystone species supporting hundreds of other organisms, and the sacred world tree of ancient Maya civilisation. It is the national tree of Guatemala and Puerto Rico, and produces kapok fibre historically used in life preservers and insulation.
Where does the ceiba tree grow?
Natively across tropical Central and South America. Introduced to West Africa and Southeast Asia early enough that it is considered naturalised in many countries. It grows best in humid lowland tropical forest below 1,000 metres elevation with 1,000-2,500mm annual rainfall.
Why was the ceiba tree sacred to the Maya?
The ancient Maya believed the ceiba was the axis mundi, the world tree connecting the thirteen heavens above, the earthly plane, and the nine levels of the underworld below. Cutting a ceiba was believed to bring misfortune. The tree was planted at the centre of villages and at cardinal points of ceremonial spaces.
What is kapok from the ceiba tree used for?
Kapok is the silky white fibre surrounding ceiba seeds. It is extremely lightweight, water-resistant, and buoyant. Historically used for life jackets, sleeping bags, mattresses, and insulation before synthetic alternatives arrived. Now reviving as a sustainable natural insulator in premium outdoor gear and acoustic products.
