This species is native to intertropical Africa and is cultivated in many regions of the world with a temperate climate, as it does not like the cold.
It is one of the world's favourite ornamental trees, both because of its beautiful appearance, with an elongated, slender trunk free of branches in its lower two thirds, and a very broad, rounded, high crown, and because of its abundant bouquets of bright red, bell-shaped flowers.
It is frequently used as an alignment tree in streets and avenues.
The flower buds store rainwater and dew water, which is retained when the flower opens, making it a plant much visited by birds and insects.
However, different studies have shown that the high concentration of sugars in its nectar is toxic to insects, especially the so-called stingless bees, and also affects hummingbirds, so it is not advisable to use this species in areas with a high concentration of these animals.

Its leaves were used in traditional medicine to treat stomach ulcers, toothache, arthritis, wounds, skin rashes, haemorrhoids and other conditions; and the bark as an antimalarial and hypoglycaemic.
In its areas of origin, its wood was used to make firewood, and for the manufacture of handicrafts and light tools.
It is a species with great invasive potential, causing serious environmental and economic problems in various parts of the world, as is the case in many Pacific and Caribbean islands, which is why it is in the catalogue of the 100 most harmful invasive alien species in the world, according to the International Union for Conservation of Nature.
