Rosen enjoys traveling worldwide and enhancing her flower and plant knowledge through experience. One of the most remarkable flowers that a horticulturist can see is the elusive Kadupul flower from Sri Lanka. While the Kadupul flower belongs to a widely-cultivated cactus species, their flowers are so elusive they don’t have a price tag. Also known as the queen of the night or Dutchman’s pipe, this flowering cactus has one of the shortest-living inflorescences. The flowers rarely bloom, as little as once a year, and each flower lasts for only one night. Its flowers immediately start to wilt once picked, making them utterly incapable of being arranged or used. The plant itself is one of the more popular cultivars and is decently hardy. It can be grown as a clinging vine or terrestrial plant, depending on the garden’s condition. Each plant can hold about 100 flowers which typically bloom synchronously.
