Usually a small tree or shrub found in pine lands, greenheart may grow to 20 feet in a moist, shaded hammock. The shiny, dark green, elliptical leaves have a rusty pubescence on their lower surfaces. Small, yellow flowers are produced in clusters. The small, dry fruit are purple-black and pop open to disperse tiny, black seeds. Greenheart grows in full sun to shade, in moist or dry locations. Colubrina makes a good hedge or screen planting due to the dense canopy.
