Deadly Nightshade? I had a panicked Mom call my Garden Center once, and she described what her toddler had eaten - and a LOT of it!
I don’t know HOW Baby managed to do that - the berries are so bitter! Anyhow, she took her to the ER just to be safe. She called us back later in the day; the kid was fine - the Mom? Not so much, LOL!
Amazingly, that evil weed is related to tomatoes!
I’ve often wondered who was the first person to think things like Pineapples, or Oysters were the least bit edible? LOL!
