Common Names: Kahili Ginger, Wild Ginger
Latin Name: Hedychium gardnerianum
Characteristics: Stems up to 2m high. Large scented flower head (25-45cm long). Lemon-yellow flowers with red stamens ( January-March). Large waxy leaves, arranged alternately on stem.
The root systems of the wild ginger spread out and send up new shoots. Very invasive pest plant. I am trying to get rid of the wild ginger. Have removed half of the plants on the land. The rest have been cut back. Will remove each clump until all are gone. This plant is nice to look at but it is invasive and a threat to native forests and plants. Grows anywhere even in the shade. Labelled as a weed in New Zealand.
For more details on this invasive pest plant see NZ Department of Conservation.
