Hedychium coronarium

Native from the Indian subcontinent to Taiwan, this plant is a perennial herb that forms dense colonies from thick underground rhizomes. Its upright leafy shoots reach about three to eight feet tall. The white flowers have broad, butterfly-shaped lips that may be tinted yellow. Their fragrance resembles gardenias and jasmine and is strongest at night. Orange capsules split open to reveal seeds with red fleshy coverings.

The flowers are used in garlands and for aromatic perfume oil. In Thailand, young buds and flowers are lightly steamed and eaten with chilli sauce. The species is Cuba’s national flower and holds the Royal Horticultural Society’s Award of Garden Merit. It has become invasive in some countries, particularly along streams and in waterlogged habitats. Photographed in Colombia.
