|Hedychium coronarium J. Koenig|
The problems with this fragrant-flowered species are very similar to those for H. gardnerianum. However, reproduction by seeds, which are not produced in large numbers, is localized because they are rarely displayed conspicuously. Long-distance dispersal is effected vegetatively by man. Its adapatation to fire is unknown but unless the fire is intense enough to harm the rhizomes it will recover. The potential for biological control is poor because of the extensive use of this species in gardens and lei making.
This species is widely distributed in wet habitats on all islands. There are major infestations above Nahiku, and Wailau Valley, Maui; and Puna and Kohala Mountains, Hawai'i.
