While this plant is listed as a medicinal herb It is considered by most farmers as a very pesky weed. Burdock in a pasture cause much trouble. The plant is large and takes up valuable grazing space, the burr ingested by animals causes choking, and sticks to any fur or hair.

Native to Europe and Northern Asia.
It is the large tap root that is mostly used in herbal medicine.

Cutting the plant out with a sharp spade and then sprinkling the remaining tap root with a bit of salt will keep it from growing back

Be careful and alert if you have Burdock growing in your yard or garden, as birds have gotten stuck on the burrs and aren't able to free themselves and die. I once read an article in a bird magazine that focused on this. Pretty sure it was Bird Watchers Digest years ago. Heart wrenching! I had tears in my eyes as I read.

Whenever I see anything in my yard and garden that even looks like a burr, I get rid of it (burrs and plant). I feed the songbirds daily, year round and don't want anything to happen to them.

Burdock's burrs were the inspiration for Velcro.
