The butterfly pea flower is popular for its colorful deep blue petals. Like its petals, butterfly pea flower tea has a vibrant blue hue and has the ability to change color from blue to purple or pink, with alterations in pH.
Butterfly pea flower makes an herbal tea with a poignant, woody and earthy scent. It can be brewed both hot and cold. When droplets of lemon juice are squeezed into the blue tea, the blue beverage drastically changes to purple.
