Royal Poinciana Tree / Flamboyant Tree
Scientific Name: Delonix regia
Light Requirement: Full sun. It needs bright, open exposure for the best flowering and canopy development.
Height: Typically 30–40 ft. tall in Florida landscapes, with a very wide canopy spread of 40–60 ft. or more when mature.
Plant Spacing: Space at least 30–50 ft. away from structures, driveways, sidewalks, pools, septic areas, and other large trees. This tree needs a large open area because the canopy becomes very wide and the roots can be surface-oriented.
Growth Habit: Fast-growing, broad-spreading flowering tree with a low, wide canopy and soft fern-like foliage. It is best known for its brilliant red-orange summer flowers.
Hardiness: USDA Zones 9b–11; sensitive to frost and prolonged cold; moderately drought tolerant once established; moderate to high salt tolerance; adaptable to a range of soil pH conditions, including mildly acidic to mildly alkaline soils, provided drainage is good.
Maintenance Info: Moderate maintenance. Royal Poinciana needs plenty of room because the canopy becomes very wide. Young trees should be pruned to develop strong branch structure and good clearance. Expect seasonal cleanup from flowers, leaves, seed pods, and small branches. Avoid planting too close to homes, driveways, sidewalks, pools, septic areas, or tight landscape beds.
Best Uses in the Landscape: Excellent as a large flowering specimen tree, shade tree, front-yard focal point, tropical accent tree, estate tree, park tree, or large open-lawn feature. It works best in spacious landscapes where its wide canopy and dramatic flowers can be fully appreciated.
Plant Info: Royal Poinciana is native to Madagascar and is one of the most dramatic flowering trees used in tropical and subtropical landscapes. The name “Royal” fits its grand, show-stopping appearance, while “Flamboyant Tree” refers to its fiery red-orange flowers that can cover the canopy in late spring and summer. Its fern-like leaves give it a soft tropical texture, but this tree needs room to spread and is best used where its full umbrella-shaped canopy can become a major landscape feature.
