Common burdock is the plant with the burrs. It is not to be mistaken for the other burr-bearing plants like cocklebur and wild licorice, both of which are native and their management is dependent on the landowners’ preference. 

The leaves of burdock closely resemble rhubarb or the ornamental elephant ear. Plants can grow between 3 and 10 feet tall and have spiny flowers that are either purple or white. Burdock produces as many as 15,000 seeds per plant. Both the flowers and burrs can trap nectar-seeking animals like bats and hummingbirds. 

Controlling burdock follows the same management advice as musk thistle, a plant most of us know well. Either use mechanical or chemical control for best results. Removing the seed heads and bagging them will prevent future infestations and removing the plant 2 to 4 inches below the soil will sever the root crown. For the enterprising and determined burdock remover, the root is edible, though it is tough and chewy if not prepared right.

In Archuleta County, burdock is widespread, but there are not many major infestations. It can grow in rangeland settings, pastureland, roadsides and along streams, but I often see it growing beneath willows and other riparian trees and shrubs.
