Deadly Nightshade?

I´ve found several suspect plants apparently camouflaging themselves among my tomato plants. Since the blossoms are similar, I assume that, like tomatoes and potatoes, they also belong to the nightshade family but the question is if they belong to the deadly variety.

That's exactly what they are!

Root them out, especially if you have small children or pets.

These plants are related to the edible tomatoes and potatoes that are commonly grown, but when unripe, the fruits and the leaves are poisonous. When ripe, the fruits are irresistible, bright shiny red.

Usually, the plant called Deadly nightshade has purple flowers and is botanically Atropa belladonna - atropine, but this one is the Evening Deadly Nightshade, or Solanum ptychanthum, with white flowers.

As well as going by the name Deadly Nightshade, it's also called Blueberry, Bonewort, Morel and Stubbleberry.

The fruits taste sweet, which is why kids are in such risk from it.

The symptoms of poisoning are dilated pupils, sensitivity to light, blurred vision, heart problems, staggering, headache, rash, flushing, severely dry mouth and throat, slurred speech, inability to pee, constipation, confusion, hallucinations, delirium and convulsions.

Get medical attention right away if a child is suspected of eating the berries or leaves!
Safe to compost?
by: Helen

Well, that's a list of horrors I could do without if I'd ever been rash enough to sample these berries! Thank you for identifying this imposter among my tomatoes.

I'm not sure if it would be safe to compost these plants because, strangely, a whole host of unwanted tomato plants suddenly started popping up in this year's compost which I'd used for sowing flower seeds.

I'd added some damaged tomatoes to my compost bin last summer and it would seem that the composting process doesn't cause the seeds to become infertile. I certainly wouldn't want the tomato's poisonous relative to appear next summer...and that's putting it mildly!
Hot Compost

You need a really hot compost to get the seeds to die.

They're quite tough, really. If you recognize the leaves, then they're easy to rogue out before they get to fruiting size.

If you pull them before they set seed, they won't reappear - this goes for tomatoes as well - it's not advised to use the volunteer seedlings, they can carry a virus.
