Yeah... Build a cage for the caster plant...
I saw that segment on the news, too.
I've read that chewing up a single bean might be a successful exit strategy.
Most of us have read or heard about Ricin... And... the taste of castor oil should be reason enough to avoid tasting them!
I've also read that aconitum shouldn't be handled without gloves... That poisonings had resulted when the cook dug carrots in the winter... and got the two mixed up...
As beautiful plants for a garden otherwise devoured by deer and rabbits, the poison garden is a good place to start... and... as most people get their food from the store... accidental poisonings seem unlikely.
But as far as jailing the plants?
At the poison garden, they have a sense of humour...
I think that most of us remember Amy Stewart's book from 2010: "Wicked Plants: The A-Z of Plants that Kill, Maim, Intoxicate and Otherwise Offend"
If you google "poison plant book"... you could find enough books to fill a shelf.
