Burdock is a biennial plant known for its large, broad leaves and distinctive purple flowers. It typically grows in temperate regions and can reach heights of up to 4 feet. The plant's roots are often used in traditional medicine and cooking, particularly in Asian cuisine, where they are valued for their nutritional benefits. The most recognizable feature of burdock is its burrs, which cling to clothing and animal fur, aiding in seed dispersal. This characteristic inspired the invention of Velcro, a fastening material that mimics the way the burrs attach to surfaces. Burdock is also considered a weed in some areas due to its rapid growth and spread.
