Well done Abigail, poster competition winner from Brodetsky Primary School! What a gorgeous drawing of a knapweed with such vibrant colours. You put a lot of effort into your research, which means you've taught us all so much about how knapweeds support bees, butterflies, hoverflies and birds too!
Last year a Brodetsky Primary School parent spotted knapweed in their garden. Perhaps you have some in yours? Take a look: https://www.inaturalist.org/observations/270146366. We hope you'll find some knapweed and add it to our map.
