Contact details - Hawke’s Bay residents can report a woolly nightshade plant by contacting HBRC’s Biosecurity team: Alice McNatty 06 833 8083 or Louise Hampton 06 833 8023. If staff are unavailable, please leave a message including name, phone number and address of the plant location.

Woolly nightshade is a fast-growing and extremely invasive plant that is widely spread throughout the region’s gardens, roadsides, and rank pasture.  It is also a health hazard, as people handling it may suffer nausea and irritation of the skin and respiratory tract.

“We want to keep a check on this plant, especially because of the health concerns.  We’ve never found it in huge numbers, but as it will grow almost anywhere in Hawke’s Bay we don’t want it spreading, like it has further north,” says Alice McNatty, HBRC biosecurity officer.

“When people contact us, we’ll come out and kill the plant at no cost to the landowner.  We will also advise them on how to control any seedlings that might pop up.”

Ms McNatty says that the shrub is flowering at the moment, so can be more easily identified by its lilac flowers.  Some plants may also be fruiting at present and it is important to ensure the berries don’t get into compost or weed piles. Woolly nightshade can quickly grow into a small tree up to 10 metres high and become more difficult to remove, so it is better to identify it and deal with it early.

Woolly nightshade - also known as tobacco weed, kerosene plant, flannel weed and eared nightshade - can be identified by its distinctive hairy, oval leaves, and small, pretty lilac flowers which are massed in clusters at the ends of branches. It forms green berries up to 18mm in diameter which yellow when ripe. Seedlings that establish in spring can flower by autumn and continue flowering.
