Ixora coccinea is a dense, multi-branched evergreen shrub, commonly 4–6 ft (1.2–1.8 m) in height, but capable of reaching up to 12 ft (3.7 m) high. It has a rounded form, with a spread that may exceed its height. The glossy, leathery, oblong leaves are about 4 in (10 cm) long, with entire margins, and are carried in opposite pairs or whorled on the stems. Small tubular, scarlet flowers in dense rounded clusters 2–5 in (5.1–12.7 cm) across are produced almost all year long
