Jasminum sambac (Oil) is a species of jasmine native to southwestern, southern, and southeastern Asia. It is the national flower of the Philippines, where it is known as Sampaguita. It is an evergreen vine or shrub reaching up to 1-3 m tall. The leaves are ovate, 4-12.5 cm long and 2-7.5 cm broad. The phyllotaxy is opposite or in whorls of three, simple (not pinnate, like most other jasmines). The flowers bloom all throughout the year and are produced in clusters of 3-12 together. They are strongly scented, with a white corolla 2-3 cm diameter with 5-9 lobes. The flowers open at night, and close in the morning. Sampaguitas do not bear seeds and the plant is cultivated solely by cuttings. The fruit is a purple-black berry 1 cm in diameter.
