Wild ginger, also known as kahili ginger and ginger lily, is a weed in many parts of New Zealand. It has long spreading rhizomatous roots and form clumps of plants.
Wild ginger grows up to 2 metres, is shade-tolerant, tolerates most soil types, good or poor drainage and fertility, and is drought and frost tolerant once established. Wild ginger will live many years, is fast growing and forms thick rhizome beds. Little or nothing will grow up through the mats of tubers, and the dense leaves block light and smothers other plants.
Seeds are spread by birds and possibly possums. Rhizomes spread slowly outward from clumps, and new plants are established from rhizome fragments spread in dumped vegetation.
