Growing or Foraging Edible Burdock Plants (Annoying Burs, Powerful Antioxidants)
The Many Uses of Burdock (Arctium Lappa)
If you have been plagued by acne, eczema or psoriasis, you have probably tried "everything in the book" to get rid of those painful (and embarrassing) conditions, so foraging for, or growing your own burdock plants may not be out of the question for you. This plant has been used as a skin remedy for many years and can be used alone or mixed with other herbs in an effort to balance out the strong cleansing action it provides.
The leaves, root, stem and seed of the plant are all edible and considered delicious by many people around the world who use and prepare the plant in many different ways so in this article, you will learn to identify the plant when foraging, and how to start growing your own. The plant is biennial, which it means it has a two-year life cycle.
Growing Burdock From Seed
Burdock plants grow better in full sun, but partial shade (if that's all you have) should be fine. You can sow burdock seeds in your garden as early as the ground can easily be worked. You will need to cover the seeds with 1/2" to 3/4" of seed starting mix (I like Miracle Gro Seed Starting Potting Mix), then tamp and water only lightly if the soil is dry. Burdock seeds will germinate quickly, usually within seven days.
Once the seedlings have grown a few inches or so, thin them out and plant them a few feet apart. When plants are young, you will need to weed frequently and keep the soil moist, but you only need to fertilize with a general purpose fertilizer about once a month. Remember, these are plants that grow very well out in the wild without any special care, so they are pretty well self-sufficient once they get established.
If you want your burdock roots to grow long, make sure the soil in which you plant them is free of rocks.
Harvesting Burdock Root
If you are planning on harvesting burdock root, be prepared for a somewhat tedious, time-consuming task. A burdock's taproot often grows to be several feet in length, and because it tends to snap easily, you will need to dig around the root (gently) to loosen and remove the soil. When foraging, it's a good idea to only harvest the number of roots you need because of the need to excavate a rather large hole. When you are done with your harvest, fill in the hole and return the area to the same condition in which you found it.
After harvesting the burdock root, scrub it well in order to remove the dirt, and peel the dark, almost black root with a carrot peeler, which will expose the white flesh of the root.
Note: Burdock roots contain approximately 2.5% protein, 0.14% fat, 14.5% carbohydrate, 1.17% ash. The antioxidant activity is considerably stronger in a burdock plant than in common vegetables and fruits.
According to MotherEarthLiving.com, foragers find the wild roots (of a burdock plant) nutty, sweet, and tender if gathered before the flower stalks appear in the plant's second year.
Edible Stems of Burdock Plants
Some people use the young stalks of a burdock plant in an Italian dish called carduni, according to The Self Sufficient HomeAcre, an interesting homesteading website where the recipe can be found.
Identifying Burdock Plants
In the early stages of development, the plant has large oblong, waxy cotyledons (embryonic first leaves) and long-petiolated triangular leaves. The stems have dark (maroon to black stem lesions) and of course, the burdock plant's fruit is easily identifiable (see photographs). The fruit, collected when they are fully ripe, are brown and grey in color, wrinkled and about 1/16 of an inch in diameter.
The fruit is an elliptic to egg-shaped, two-chambered bur that can be up to about an inch and a half long. It is covered with hooked prickled. Each of the burs has two seeds inside, one that will grow during the first year and the other that grows a year later. Projectings from the tip of the bur are two prickles which are longer and wider than the other prickles.
Some people tend to confuse this plant with giant ragweed, but the cotyledons of the burdock plant are longer and more linear than those of the ragwood.
Velcro Invention Inspired by Burdock Burs
The annoying burs from a burdock plant were the inspiration for the inventor of Velcro, George de Mestral. While hunting in Switzerland in the 1940's, this Swiss engineer wondered how the cockle-burs remained attached to his pants and the fur of his dog and began developing the phenomenal fabric in 1948. Velcro was patented in 1955.

Burdock Popular in Japan
The Japanese consider the burdock plant to be an important cooking ingredient. Pickled burdock (gobo), available in packages in Japanese markets, is often served with sushi. Burdock is also used in makizushi (Japanese sushi rolls with various fillings), another popular Asian dish.
