33. potentilla ? I don't awfully like it, but all the elements are there - potent (strong) ill (poorly) + a , though I don't understand the rest of it.
thank you kettledrum-I'd only come up with belladonna( possible link to strong medication for being poorly) for that one, and your answer makes a lot more sense.
hopefully I can repay a very small amount of the enormous help given to me by smouse for the new shoots quizzes-solve the 2 three word clues, and its an anagram of those 2 words-I had never heard of the answer until I put the two answers into an anagram solver, then checked in a dictionary. Not surprising as its a plant from "up north". Agree with Kettledrum, Hornbygirl & Ladyalex on the other answers.
