I've actually been to the Poison Garden DR. It's fascinating but just don't touch anything and then lick your fingers.
That sounds handy! I used to grow Castor beans but I worried what if the neighborhood kids got into them... so I stopped. Ditto with breadseed poppies, which are illegal anyway. I still grow helleborus, daffodils, rhubarb, potatoes, and vinca. There are probably other toxic plants there too.
