I don't know now. Not so much because it's poisonous, but because many of you called it a weed, and to me, sounds like it would take over the garden. I certainly don't need that, especially since I'm 'downsizing' the garden.
Just a bit of info I found:
Effects of ingestion
Due to the potent combination of anticholinergic substances it contains, Datura intoxication typically produces effects similar to that of an anticholinergic delirium (as contrasted to hallucination): a complete inability to differentiate reality from fantasy; hyperthermia; tachycardia; bizarre, and possibly violent behavior; and severe mydriasis with resultant painful photophobia that can last several days. Pronounced amnesia is another commonly reported effect.[14]
A complete inability to tell reality from fantasy? I certainly don't need (more) of that! Bizarre behavior? Don't need anymore of that either! Amnesia? Got that covered already!
