This week it's a plant for you to identify. Do you know what it is? It has medicinal qualities and can be found all over the place, in parks and meadows. You might even have some growing on your school field or in your garden. 

I'll give you a clue - it has 2 words in it's name.

Find out on Sunday if you were right!
