Said to be ‘World’s Most Expensive Flower ‘in the world, the Kadupul Flower is completely priceless. The Chinese refer to it as a ‘flash in the pan’ The Sri Lankans consider the flower so rare that they believe it to be descended from the heavens. The captivating velvet 5-leaved Kadupul Flower is one of the shortest-blooming flowers in the world, blooming only once a year, and as it does, it starts to wilt. The flowers last less than one hour and fill the night air with a soft, soft, striking fragrance, turning even the most dull man into a poet.
