Nyctanthes arbor-tristis is a shrub or a small tree growing to 10 m tall, with flaky grey bark. The leaves are opposite, simple, 6–12 cm long and 2–6.5 cm broad, with an entire margin. The flowers are fragrant, with a five- to eight-lobed white corolla with an orange-red centre; they are produced in clusters of two to seven together, with individual flowers opening at dusk and finishing at dawn. The fruit is a flat brown heart-shaped to round capsule 2 cm diameter, with two sections each containing a single seed.

Parijat (Nyctanthes arbor-tristis), appears in several Hindu religious stories and is often related to the Kalpavriksha. In one story, which appears in Bhagavata Purana, the Mahabharata and the Vishnu Purana, parijat appeared as the result of the Samudra manthan (Churning of the Milky Ocean) and Lord Krishna battled with Indra to win parijat. Further on, his wife Satyabhama demanded the tree be planted in the backyard of her palace. It so happened that in spite of having the tree in her backyard, the flowers used to fall in the adjacent backyard of the other queen Rukmini, who was favourite of Lord Krishna.
