Hedychium is a genus of flowering plants in the ginger family Zingiberaceae, native to lightly wooded habitats in Asia. There are approximately 70-80 known species, native to India, Southeast Asia, and Madagascar. Some species have become widely naturalized in other lands, and considered invasive in some places.^[1][2]

The genus name Hedychium is derived from two ancient Greek words, hedys meaning "sweet" and chios meaning "snow". This refers to the fragrant white flower of the type species H. coronarium.^[3] Common names include garland flower, ginger lily, and kahili ginger.
