Wicked (Poisonous) Weeds & Pretty Flowers

Nick Roy spots suspect flower on CM, sends sample to UK expert, and confirms we do have Cressleaf Grounsel growing in Adair County, KY. Cressleaf Grounsel can be a threat to cattle. He touches on two other common but little known plants, Poison Hemlock, and Perilla Mint. There's also a fascinating YouTube video from Voice of America with a huge surprise about what one author, Amy Stewart, thinks is the most wicked plant in the world, the one which kills more people worldwide than any other: Shouldn't be a surprise to Adair Countians.

Nick Roy, Adair County agent for Agriculture and Natural Resources, noticed something amiss with the plant growing in the Green River Commerce Park with the beautiful yellow flowers.
