Care

Light exposure

The flamboyant demands maximum sunlight (6 to 8 hours minimum) to flower generously. Place it in full sun all day long. In shade, growth slows and flowering becomes very sparse.

Watering

Water regularly during the growing season (spring-summer), then reduce drastically in winter. Once established, it tolerates dry periods well. Avoid standing water which could rot the roots.

Soil and drainage

Prefer a light, well-draining and fertile substrate. The flamboyant adapts to poor soils but fears waterlogging. In a pot, use rich potting soil mixed with sand or clay balls.

Fertilizing

Feed the tree from spring to autumn with balanced fertilizer or one slightly rich in potassium to promote flowering. Reduce applications in winter or give the tree a rest period.

Pruning and shaping

Pruning isn't essential, but you can balance the shape after flowering by removing poorly placed branches. Remove dead or crossing branches to open up the crown.

Pests and diseases

Watch for mealybugs and whiteflies indoors. Root rots appear if watering is excessive. Ensure good air circulation and respect rest-growth cycles to prevent these issues.

Did you know?

The flamboyant is nicknamed the 'flame tree' because of its spectacular red-orange flowering that covers the entire crown. In Madagascar, its island of origin, it has symbolized celebration and festivity for centuries. In Africa and the Caribbean, it's planted in public squares or parks since its flat shape and shading make it perfect for public spaces.

Where to buy it

Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
