White butterfly ginger lily, or simply ginger lily, is a tropical perennial and a cousin of culinary ginger (Zingiber officinale) of bread, snap and ale fame. It's green stalks grow from thick rhizomes to a height of 3-7 ft (0.9-2.1 m). Leaves are lance-shaped and sharp-pointed, 8-24 in (20-61 cm) long and 2-5 in (5-12.7 cm) wide and arranged in 2 neat ranks that run the length of the stem. From midsummer through autumn the stalks are topped with 6-12 in (15.2-30.5 cm) long clusters of wonderfully fragrant white flowers that look like butterflies. The flowers eventually give way to showy seed pods chock full of bright red seeds.
Ginger lily, Hedychium coronarium is native to India. It is a popular landscape plant throughout Florida, the Gulf Coast, California, the Caribbean and tropical and subtropical areas worldwide. Ginger lily also is grown in mild winter temperate regions of North America and Europe where it dies back in winter but re-emerges in spring.
