Tabernaemontana divaricata (Apocynaceae), commonly called pinwheelflower, crape jasmine, East India rosebay and Nero's crown is an evergreen shrub native to India and now cultivated throughout South East Asia and the warmer regions of continental Asia. In zones where it is not hardy it is grown as a house/glasshouse plant for its attractive flowers and foliage. The stem exudes a milky latex when broken, whence the name milk flower (দুধফুল), টগর or কাঠমল্লিকা in the Bengali language..
It is called as ‟నందివర్దనం” ‟ Nandi Vardhanam” in Telugu language and "நந்தியார்வட்டை" "Nandiar vattai" in Tamil and "Nanthyaar vattam" (നന്ത്യാർവട്ടം) in Malayalam and Nandi battalu (ನಂದಿ ಬಟ್ಟಲು) in the Kannada language. Other Indian names include chandni and taggar. It is known as wathusudda වතුසුද්ද (meaning "Garden White") in the Sinhalese language. In Cambodia, it is called phka nuon srei ផ្កានួនស្រី or phka dâk khut ផ្កាដកឃុត. The plant contains several alkaloids and, like many other Apocynaceae, is toxic and medicinal.

The plant generally grows to a height of 5–6 feet (1.5–1.8 m) and is dichotomously-branched. The large shiny leaves are deep green and about 6 inches (15 cm) in length and 2 inches (5.1 cm) in width. The waxy blossoms are found in small clusters on the stem tips. The (single) flowers have the characteristic 'pinwheel' shape also seen in other genera in the family Apocynaceae such as Vinca and Nerium. Both single and double-flowered forms are cultivated, the flowers of both forms being white. The plant blooms in spring but flowers appear sporadically all year. The flowers of the single form are unscented but the double-flowered form has a pleasing fragrance.
The roots have a bitter taste.
The leaves of this plant are eaten by the caterpillars of the Oleander Hawk-moth (Daphnis nerii).
Plant has been reported to contain a variety of alkaloids, including, in the bark of the stem and root including tabernaemontanine, coronarine, coronaridine, and dregamine. Alkaloids are present in all the vegetative parts of this shrub.
