W**D OF THE DAY: Woolly nightshade / to***co w**d.
Nasty, nasty, nasty. Surely one of our worst w**ds, for a whole host of reasons. Woolly nightshade is rife in Northland, including in Kerikeri.
It's rarely found within intact bush but it's common alongside roads and forest margins, and anywhere the original vegetation has been disturbed.
It grows fast and can crowd out native plants; it also poisons the soil, which stops native plants taking hold. It produces lots of seeds, starting it its first few months of life.
And its grey-green leaves are covered in fine, fur-like hairs that come off when touched, irritating the skin, eyes, and lungs. Definitely a plant to be avoided if you have asthma.
Oh, and the berries are (mildly) toxic to humans. It even smells bad.
It regrows quickly when cut down so the stumps needs to be poisoned to stop it coming back. Like we said, nasty...

And in case you're wondering, yes, it is related to to***co. Both are members of the nightshade family. But for god's sake don't try smoking woolly nightshade, it is toxic as well as a skin irritant.
