THE Delonix regia is a majestic tree that exhibits several remarkable characteristics:

Size and wear In Mauritius, the flamboyant tree can reach between 10 and 15 meters in height. Its characteristic umbrella-shaped form, with a wide and spreading crown, makes it a highly valued shade tree. When mature, its canopy can extend to a width equivalent to its height.

Trunk and bark The trunk, smooth and grayish to light brown in young trees, can reach up to 2 meters in circumference. The bark becomes rougher with age. The wood, of moderate density, is relatively brittle but resists moisture and insects well, although it remains susceptible to termites.

Foliage The flamboyant tree's leaves are bipinnate, measuring between 30 and 50 centimeters in length. They have 11 to 18 pairs of pinnae, each divided into 20 to 30 pairs of small, oval leaflets, 5 to 10 millimeters across. This light green foliage, finely cut and held horizontally, resembles a fern frond and lends lightness and movement to the tree's imposing mass. The flamboyant tree is deciduous, losing its leaves for several months of the year, particularly during the dry season.

The spectacular flowers

The flowering of the flamboyant tree is one of the most remarkable natural spectacles in Mauritius. The flowers only appear on trees that are at least 10 years old.

Floral structure Each flower measures approximately 8 to 15 centimeters in diameter. It consists of five petals: four upright, spatulate, scarlet petals with wavy margins, and a fifth, larger, slightly rounded petal that stands upright in the center and displays white or yellow streaks. The calyx is formed of five flat, lanceolate sepals. Ten long, upward-curving red stamens emerge dramatically from the center of the flower.

Colors Although the red variety is the most common in Mauritius, there are also orange and yellow-flowered varieties. In 1984, a yellow-flowered variety originating from Trinidad was introduced to Mauritius.

Honey-producing properties : The flowers of the flamboyant tree are melliferous, secreting abundant nectar which is collected by bees and transformed into good quality honey.

Fruits and seeds

After flowering, the flamboyant tree produces long, woody pods characteristic of the Fabaceae family. These pods can measure between 40 and 60 centimeters long and 4 to 5 centimeters wide. They sometimes remain on the tree until the following season. The elongated, hard seeds are brown and can be used for propagation. Caution: flamboyant tree seeds are toxic and should not be ingested.

History of the flamboyant tree in Mauritius

Introduction by Wenceslas Bojer

The history of the flamboyant tree in Mauritius is closely linked to the Czech botanist and naturalist Wenceslas Bojer (1795-1856). Born in Bohemia, Bojer arrived in Mauritius in 1821 and was quickly sent to Madagascar by Governor Robert Townsend Farquhar.

It was during his exploration of Madagascar in 1824 that Bojer discovered the flamboyant tree and sent seeds to Mauritius. He returned to Mauritius in 1824-1825 with pods of this spectacular tree. The first flamboyant tree was planted in Port Louis and in the Pamplemousses Botanical Garden. Thanks to Bojer's efforts, supported by his friend Charles Telfair who hosted him on his Bois-Chéri estate in Moka, the flamboyant tree was gradually spread throughout the island.

In the 1830s, again through Bojer's efforts, the flamboyant tree was propagated from Mauritius to other tropical regions, notably Sri Lanka and India, making Mauritius a starting point for the global spread of this iconic tree.

Expansion across the island

Following its successful introduction, the flamboyant tree quickly spread throughout Mauritius. It was initially planted in public spaces, along streets, in squares, and as a shade tree in tea plantations and dairy farms. Gradually, it also became established in the courtyards of private homes, becoming an integral part of the Mauritian landscape.

Flowering: an eagerly awaited annual spectacle

Flowering period

In Mauritius, the flamboyant tree blooms mainly from November to January, transforming the island into a living tapestry of scarlet hues. This spectacular flowering coincides with the festive end-of-year period, making the flamboyant tree a true symbol of Christmas for Mauritians.

Flowering typically occurs towards the end of the dry season and the beginning of the rainy season. Before the flowers appear, the tree loses all its leaves for a few weeks, which might lead novices to believe it is dead. Then, spectacularly, the tree is covered in clusters of scarlet flowers before the new foliage develops.

Cultural significance

For Mauritians, the flamboyant tree holds deep cultural significance. When the flamboyant trees begin to turn red, everyone knows that Christmas is approaching. While Europeans see the fir tree as a symbol of Christmas, Mauritians consider the flamboyant tree their natural Christmas tree.

Truck helpers, perched high up in their vehicles, often pick bunches of flowers during this period and place them on the front of their truck as a symbol of happiness and prosperity for the coming new year.

The flamboyant tree is also known in Mauritius by the local names "Pied Bonus" (bonus tree) or "Bouke Banané" (annual bouquet), highlighting the population's particular attachment to this tree.

Uses and properties of the flamboyant tree

Ornamental and practical uses

Shade tree Thanks to its umbrella-shaped canopy, the flamboyant tree has traditionally been used as a shade tree in tea plantations, dairy farms and along avenues.

Honey production : Honey-producing flowers allow bees to produce good quality honey.

Drink Although flamboyant wood is relatively fragile, it offers resistance to moisture and insects. It can be used to make lightweight structures such as canoes. It is also often used as fuel.

Eraser A thick yellowish or reddish-brown gum can be extracted from the seeds, which could find applications in the textile and food industries.

Craftsmanship The hard, elongated seeds are sometimes used to make original necklaces and bracelets.

Medicinal properties

The flamboyant tree possesses various medicinal properties recognized in traditional medicines:

Bark The bark has various medicinal properties. It can be used as an infusion to treat diarrhea, with great care. The aqueous extract of the bark has emetic properties and can be used against poisoning. The bark is also macerated and applied as a poultice to relieve rheumatic pain.

Flowers The flowers are known to be an excellent vermifuge. They are also used to treat respiratory problems, coughs, and asthma. In some regions, the flowers are heated and given as an oral remedy for respiratory complications. The flowers possess antibacterial properties.

Roots The roots are used against fever in traditional medicine.

Leaves The leaves are known for their antibacterial properties. In some regions, particularly in Bangladesh, they are used to treat diabetes, although there is a lack of in-depth scientific studies to support this use.

Active compounds Scientific studies have identified flavonoids and triterpenes in the flamboyant tree, which have analgesic properties. Flavonoids also possess high antioxidant capacity. Extracts of flowers and seeds have shown antifungal activity.

Attention It is important to note that the seeds of the flamboyant tree are toxic if ingested. Consuming an infusion of the seeds or roots is not suitable for pregnant women, as it is a uterine stimulant that acts as a potent abortifacient. The medicinal use of flamboyant should always be carried out under expert supervision.

Cultivation and care of the flamboyant tree

Climatic conditions and soil

The flamboyant tree thrives in the tropical climate of Mauritius. It prefers:

• A hot, dry climate in winter, humid in summer
• Average annual temperatures between 14 and 26°C
• Winter temperatures above 5-10°C
• Annual rainfall between 700 and 1200 mm
• An altitude between 0 and 2,000 meters
• Full sunshine all year round
• A light, well-drained, preferably sandy soil
• An open environment

Once established, the flamboyant tree can withstand periods of drought. It tolerates most well-drained soils and particularly appreciates the light soils of Mauritius.

Multiplication

From seeds This is the most common method. The seeds must first be scarified (to break the hard outer layer) and then soaked in water for two days. They are then sown in pots, about 3 centimeters deep, in fresh, humus-rich soil. The pots should be placed in a sunny, sheltered spot. Germination can take time and requires patience.

By cuttings Although less common, propagation by cuttings is also possible.

Planting precautions

The flamboyant tree's root system is highly developed and very widespread. It can:

• Disrupting nearby plant crops
• Lifting the paving stones and sidewalks
• Damaging the foundations of homes

It is therefore recommended to plant the flamboyant tree at a sufficient distance from buildings and infrastructure.

Parasites and diseases

Since 1957, the hemipteran insect Cerneura delonixia (A leafhopper) attacks the leaves of the flamboyant tree in Mauritius, giving them a brownish tint before they fall in winter. However, the flamboyant tree remains generally a robust tree, practically free from serious diseases and major pests.

Conservation and environmental issues

Status in Madagascar

Paradoxically, while the flamboyant tree thrives throughout the world's tropical regions, it is currently endangered in its natural habitat in Madagascar. Habitat loss due to slash-and-burn agriculture and deforestation seriously threatens this species on its native island. The flamboyant tree's exact place of origin, discovered by the botanist Leandri in 1932, is in the native forests of Antsingy and the Mariambola Gorge in western Madagascar.

Preservation in Mauritius

In Mauritius, some observers are concerned about the gradual disappearance of iconic flamboyant trees. Many trees disappear each year for various reasons: old age, disease, increasing urbanization with its concrete and asphalt, or simply because owners refuse the daily chore of sweeping up the leaves and flowers.

Once-famous avenues, like the one in Montagne Ory, have disappeared. The flamboyant tree on the Grand-Rivière-Nord-Ouest bridge, immortalized in cultural works, is no more. Given this situation, it would be advisable to implement a systematic replanting policy to ensure the survival of this emblematic tree in the Mauritian landscape.

The flamboyant tree in Mauritian culture

The flamboyant tree holds a special place in the imagination and daily life of Mauritians. Its spectacular late-year bloom marks the rhythm of the seasons and heralds the festive period. The tree has become a symbol of Mauritian identity, just like other emblematic elements of the island.

Photographers, both professional and amateur, eagerly await the flamboyant tree's bloom each year to capture those magical moments when the island is adorned in its most beautiful colors. Postcards and artworks depicting flowering flamboyant trees are ubiquitous and are sought-after souvenirs for tourists.

Beyond its aesthetic appeal, the flamboyant tree embodies the bounty of tropical nature, the Mauritian joie de vivre, and the ephemeral beauty of things. Each year, its life cycle reminds the inhabitants that beauty deserves to be celebrated and that each season brings its own wonders.

Conclusion

The flamboyant tree (Delonix regiaThe flamboyant tree is much more than just an ornamental tree in Mauritius. It is a cultural symbol deeply rooted in Mauritian life, a temporal marker of the festive season, and a heritage element of the island's landscape.
