I've recently fell in love with learning about poisonous plants and want to start gardening them. I think Monkshood looks absolutely beautiful. Only problem is it's so poisonous, even touching it can kill you. Somehow it used to be used in traditional medicines, but god knows how.

If I start growing these poisonous plants, is there any practical value I can get out of them? Is there a legal way to make money off the hobby? No, I would never sell anything to an aspiring murderer or someone who wishes to inflict illegal harm on someone. I would sell it to a company or the government though if it's legal regardless of their intentions. Is there any kind of business I can form off this?
