Edible blue flowered vinet from Thailand. Gorgeous, huge, double blue blooms make a natural food dye and soothing tea to calm the nerves. This double-flowered type was found in Thailand, where the blooms are used to dye everything from teas to rice and desserts. A gorgeous ornamental edible flower, the vines are smothered in dazzling indigo petals. Our favorite kid-friendly drink; when you add a drop of lemon to the deep blue tea, the color instantly turns a bright pink, like magic! Natural Pink Lemonade, anyone? A fine variety.
