Hamelia patens is native to the American subtropics and tropics. Its range extends from Florida in the Southern United States to as far south as Argentina. It grows best when well supplied with moisture and prefers a full sun to partial shade location in the landscape . In Kampala, this tree can be found within Makerere II zone C, at Upper Kololo terrace, Phillip road among other places.

It's a fast-growing tree. A hedge of firebush needs regular clipping, and flowers are often removed during this process.
