Plumeria obtusa is a small tree, growing 3.0–4.6 m (10–15 ft) tall. Infrequently, individuals can grow to be 7.6 m (25 ft). Its flowers are white with yellow throats and each has five petals. The fragrant flowers bloom in clusters. Leaves are dark green, glossy, and up to 20 cm (8 in) long. They are obovate, or teardrop-shaped .
This plant is commonly used as an ornamental, grown for its flowers. In Cambodia the flowers are used to make necklaces and in offerings to the deities. In traditional medicine used in that country, a decoction of the bark is given in varying doses as a purgative or as a remedy against oedemas.
