-------------------------------------
Hedychium gardnerianum (herb)
This showy ornamental ginger grows over a metre tall in wet climates and grows from sea level to an altitude of 1,700 metres. It displaces native plants, forms vast, dense colonies and chokes the understory vegetation. It may also block stream edges, altering water flow. It is dispersed by birds over short distances and by man over long distances (as garden waste or via the horticultural industry). Even small root fragments will resprout, making it a difficult invasive to control.
Common Names: awapuhi kahili, cevuga dromodromo, conteira, Girlandenblume, Jin jiang hua, kahila garland-lily, kahili, kahili ginger, kopi, sinter weitahta, sunkevara, wild ginger

Kahili ginger grows almost as an invasive plant in some areas of this island. At the Volcanoes National Park on the Big Island, they are trying to eradicate it as much as possible as it takes over the areas where some native plants are growing.
I think they are beautiful and used to have some growing in the place where we were previously living. Very fragrant and beautiful!
The name kahili (kah -he -lee) is named for the old yellow feather standards carried by attendants of the old Hawaiian Ali'i (royalty) since it resembles them in shape.
Tall perennial which produces rhizomes, long lance shaped leaves which can be glossy green or a greyish colour.
The flowers and scented and held in a dense cylinder manner, pale to bright yellow flowers have long red stamens which are very visible.
Frost tender but can be grown out side in zones 8 and above with a deep winter mulch.
