About moth plant

Moth plant is a highly invasive pest plant which threatens and smothers our native biodiversity. Each pod contains up to a thousand seeds, which can germinate in established forest and streamside plantings a long way from the seed source. Then it gets right into the canopy and smothers and kills plants, preventing the establishment of natives.

There’s lots of great information on the Auckland Council and Weedbusters websites.

Moth plant pods are just about ready to pop during autumn, and every pod you remove during the competition will help stop the spread.

Help your local community to control this pest plant so our backyards can thrive.
