Hedychium Explained
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, meaning "sweet" and 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.
Members of the genus Hedychium are rhizomatous perennials, commonly growing 120- tall. Some species are cultivated for their exotic foliage and fragrant spikes of flowers in shades of white, yellow and orange.[4] Numerous cultivars have been developed for garden use, of which 'Tara' has gained the Royal Horticultural Society's Award of Garden Merit.[5] [6] Though reasonably hardy down to -10C, it requires a sheltered position and a deep mulch in winter.

Taxonomy and phylogeny
In 2000, Tom Wood et al. published the first phylogeny of the genus Hedychium represented by 29 taxa.[7]
Reproductive biology
Hedychium has multiple modes of reproduction: sexual, via rhizomes and via bulbils. Some species of Hedychium are reported to exhibit facultative vivipary.[8]
