Yellow trumpetbush is a ruderal species, readily colonizing disturbed, rocky, sandy, and cleared land and occasionally becoming an invasive weed. It thrives in a wide variety of ecosystems, from high altitude temperate forests and tropical deciduous and evergreen forests, to xerophilous scrub and the intertropical littoral. It quickly colonizes disturbed, rocky, sandy, and cleared fields. The species prefers dry and sunny regions of the coast.
