Blue Butterfly Pea Flower - Clitoria Ternatea

This herb has different names such as blue-pea,  bluebellvine, cordofan pea, Darwin pea and Asian pigeonwings, butterfly pea (Clitoria ternatea L.). It is a plant from the Fabaceae (Leguminosae) or pea family. Its origins can be traced to tropical Asia, and through the centuries it was widely distributed in the West and East Indies, and then on to Central and South America, India and China.

Butterfly pea flower usually used for tea, it has a woody and earthy flavor that's reminiscent of green tea. However, what's most interesting about this exotic tea is its ability to change colors. The secret lies in its pH level — the drink changes color depending on the pH of any ingredient that's added to it.

At its first brew, the beverage has a deep, midnight blue color. If you add a squeeze of lemon or any acidic liquid, it changes to a beautiful, rich violet. Add hibiscus flowers and the drink will turn bright red.
