Negative plant_it On May 26, 2011, plant_it from Valparaiso, IN wrote:

Tap roots go to 4 ft, hard to get rid of. Biennial plant that develops horrible burs in second year. Little redeeming value to wildlife. Deer will browse this plant only if no other food is available. Burs stick to clothes, animal fur and can even be fatal to birds: "Common Burdock (Arctium minus) is an invasive, exotic plant that can be deadly to small birds like kinglets, warblers and bats. Burdocks burrs act like Velcro to trap birds and bats unfortunate enough to come in contact with them." http://www.wihumane.org/wildlife/burdock.aspx

I love burdock (to eat) and so decided to grow some from seed in my garden - big mistake! It is terribly invasive and difficult to get rid of. I realized later that our community garden actually forbids growing it. It grows to a huge plant (8 ft or so?) with very deep, thick roots (much deeper than I can dig). It has tough woody stalks that must be sawed off. The seeds are borne in prickly seed burrs, which stick to clothing and everything else, so it's very difficult to avoid spreading seeds around. It regrows from a small piece of root left in the ground, which is almost inevitable. So beware!

Every part of the plant is edible. I make salads out of newer leaves, eat fresh roots, cut the stalks, and use them like cellery, and also dry the roots and leaves out to make teas.
The flower can also be used, befor the seeds develope.

Burdock has a very long history of medicinal use. As with any other medicine, only a trained herbalist should prescribe for serious ailments. First-aid remedies include a topical relief for minor bites and rashes.

Burdock is a pasture weed, but is also grown for its edible roots, which are said to taste like artichoke and can be eaten raw or cooked.
