Woolly Nightshade poisons the soil around it which inhibits our native species from growing. Help stop the spread!
Woolly Nightshade or Tobacco Plant (Solanaceae – Solanum mauritianum) produces toxins that poison the soil (is Allelopathic) which inhibits the growth of other species. Woolly Nightshade matures quickly, producing a purple flower which soon yields yellow fruit that birds find attractive and readily spread.
The berries are moderately toxic to people (especially children) and to livestock. The leaves shed fine hairs when touched, which irritate the skin, eyes, nose and throat and in some cases cause trouble with breathing. Anecdotal evidence would suggest that birds that gorge themselves on the seed may be poisoned.
Woolly Nightshade is in our Dirty Dozen because it spreads and grows quickly, poisoning the soil around it which inhibits the growth of other species and because it presents a health risk.
How you can help…
You can remove it by pulling out small seedlings leaving them onsite for the roots to rot or apply herbicide to remove them. We find BambooBuster from Cut’n’Paste works well(nb. MetGel doesnt work for the Solanaceae family), for the best outcome you should cut just above the ground and quickly (within a few seconds) apply the gel or remove bark every 10cm and paste patches of the gel over the bare area. Try working in pairs, one cutting and the other pasting. Please always read the instructions on the label and wear protective clothing.
