Common Burdock's flowers somewhat resemble thistles, but it has large, broad leaves and hooked bracts (the green bristles that are part of the flower head). Purportedly, the hooked bracts were the inspiration for Velcro®. It is a biennial plant, producing flowers in its second year of growth.
Common Burdock is native to Europe, and is sometimes considered invasive in the Mid-Atlantic area.
