How well do you know your weeds?

You can test your knowledge of weeds against our online quizzes.

Our easiest quiz gives you a picture of the weed and prompts you to type in the weed's common name. Our advanced quiz also gives you a picture of the weed, but you have to select its correct botanical name from a dropdown list.

Both quizzes are unmonitored, so we're afraid we won't be able to congratulate you when you answer all the questions correctly. Both quizzes circulate through the entire database, so you can either test your knowledge against all the weeds we have, or leave the quiz whenever you wish.
