Common Burdock, Arctium minus
Although not listed by the State of Massachusetts as an invasive plant, Common Burdock is certainly growing invasively at Fresh Pond Reservation. A biennial, during its first year it produces a low rosette of large leaves that die back in the winter. In its second year it grows a tall stem with smaller leaves. The thistle-like flowers produce hook-covered balls of seeds that stick to fur and clothing.

The root of common burdock is edible raw or cooked. The best roots are obtained from young plants. They are usually peeled and sliced. The roasted root is a coffee substitute as well. Young leaves and leaf stems are edible raw or cooked, and have been used as a potherb. They are mucilaginous. It is best to remove the rind from the stem. Young flowering stems are edible, peeled and eaten raw or cooked like asparagus. Seed sprouts are reportedly edible too.
