    Hedychium gardnerianum

    Kahili Ginger (Hedychium gardnerianum) is a large ginger native to the Himalayan region. In optimal growing conditions it can reach eight feet tall. This plant produces beautiful yellow inflorescences that make it one of the most widely cultivated species of ginger. It can be grown in tropical regions and somewhat subtropical climates.

    Problems in Hawaii

    Kahili ginger is one of Hawaii’s worst noxious weeds. It is particularly invasive in Kauai, such as in Koke’e. However, it has not invaded the small island of Molokai yet. Hawaii shares its conservation concerns with New Zealand, where the plant has become a pest as well.
