About

Tabernaemontana is a genus of flowering plants in the family Apocynaceae. It has a pan-tropical distribution, found in Asia, Africa, Australia, North America, South America, and islands of the Indian and Pacific Oceans. These plants are evergreen shrubs and small trees growing to 1–15 m tall. The leaves are arranged in opposite pairs, 3–25 cm long, with milky sap; hence it is one of the diverse plant genera commonly called "milkwood". The flowers are fragrant, white, 1–5 cm in diameter.

The cultivar T. divaricata cv. 'Plena', with doubled-petaled flowers, is a popular houseplant.
