Blue pea flower or bunga telang is a perennial herbaceous plant. Its leaves are elliptic and obtuse. It grows as a vine or creeper, doing well in moist neutral soil. The most striking feature about this plant are its vivid deep blue flowers. They are solitary, with light yellow markings. They are about 4 cm long by 3 cm wide. There are some varieties that yield white flowers. In Southeast Asia the flowers are used to colour food. In Malay cooking, an aqueous extract is used to color glutinous rice for kuih ketan (also known as pulut tai tai in Peranakan/Nyonya cooking) ,nasi kerabu and in nonya zhang.
