Royal Poinciana Tree

The royal poinciana tree is known by two other fitting names: the flamboyant tree and the peacock tree. The tree, a part of the pea family, originated in Madagascar, and it grows striking flowers that range from scarlet to orange in color. Its compound leaves can reach from 1 to 2 feet.

The royal poinciana tree is a fast grower, and it can reach its ultimate height, around 40 feet, in a relatively rapid amount of time, despite it having the reputation as a rather picky plant that cannot tolerate areas that receive frost. As such, in the United States, it’s most often found only in Florida.

Besides growing relatively quickly, the tree also will grow in many types of soil conditions and become highly drought resistant, though it needs regular watering when it’s young. Mature trees can also tolerate sand. They cannot survive in cold temperatures, such as anywhere that gets frost coverage.

The royal poinciana tree has a preference for sun, however, and its thick foliage will likely kill the grass beneath it. New royal poincianas often take five years to bloom, though sometimes they can take up to 12 years. On occasion, only one portion of the tree will flower, but this is normal and infrequent in healthy specimens.

Much like how the plant can handle many different types of soil, there isn’t exactly the best kind of royal poinciana fertilizer. A good quality granular type of fertilizer is recommended. Ideal times to fertilize are spring, summer, and autumn.

To achieve a strong tree structure, gardeners are recommended to prune regularly, most often before spring regrowth starts in late March or April. This is necessary because the tree’s branches break quite easily in high winds.

Pruning helps strengthen the branches and ensures they stay affixed to the trunk. Prune any branches that grow to be half the diameter of the trunk for best results. Pruning the lower branches also gives an area for people to sit in shade during the summer.
