Native to Central America. Calliandra species have long been popular in the tropics as ornamentals due to their red flower heads. This species has been planted for forestry purposes, especially as quick-growing fuelwood. Brought very recently to Uganda; does well in a variety of soils, including acidic ones, 1,500-2,000 m. Performs better at higher altitudes than Leucaena and tolerates several months of drought but does best with high rainfall. It does not tolerate waterlogging. In Kampala, Calliandra can be found within Uganda Golf Course Club, Makerere II zone C, Kitante courts among other places.

Very fast growing on good sites: lopping, coppicing.
