Butterfly pea flower is a vibrant blue flower from the plant species Clitoria ternatea. It is native to tropical Asia and is often used in traditional medicine and culinary dishes. The flower is known for its striking color, which comes from natural pigments called anthocyanins. In addition to its aesthetic appeal, butterfly pea flower is popular for making herbal teas and beverages. When steeped in hot water, the petals release a deep blue hue, which can change to purple or pink when mixed with acidic ingredients like lemon juice. This unique color-changing property makes it a favorite in creative drinks and cocktails.
