Burdock is a native of Eurasia but has quickly become naturalized in North America. The plant is an herbaceous biennial with a long history of edible and medicinal use by native people. For gardeners who wish to try growing burdock plants, seed is available from numerous sources and the plant is adaptable to any light level and most soils. This is an easy plant to grow either as an herbal medicine or as an interesting vegetable. As a part of your medicinal or edible garden, very little burdock plant care is necessary once established.

About Burdock Plants

Burdock occurs in undisturbed sites where the plant forms a rosette the first year and a flowering spike the second. Both the roots and young leaves and shoots are edible. The plant is easy to grow and can produce roots up to 2 feet long in 100 days or less. Gardeners who want to know how to grow burdock should know that it is easier to harvest roots if planted in sandy, loose soil.

Burdock may reach 2 to 9 feet in height and produces rough, sticky burred fruits. From these fruits comes its scientific name, Articum lappa. In Greek, ‘arktos’ means bear and ‘lappos’ means seize. This refers to the fruits or seed capsules which are barbed with spurs that grab onto animal fur and clothing. In fact, from these fruit, it is said the idea from Velcro was developed.

The flowers are bright pinkish-purple and similar to many thistle species. The leaves are broad and lightly lobed. The plant will self-seed readily and can become a nuisance if not managed. This should pose no problem if you are continually deadheading the plant or if you intend to use it as a root vegetable. Another way to contain the plant is by growing burdock in pots.

Burdock Plant Uses

Among the many burdock plant uses is in the treatment of scalp and skin problems. It is also known to be a liver treatment and stimulates the digestive system. It is a detoxifying herb and diuretic and has also been used as an antidote in some cases of poisoning.

In China, the seeds are used to treat colds and cough. Medical uses of burdock stem from the plant’s use in tinctures and decoctions resulting in salves, lotions and other topical applications.

It is also a popular food plant, known as gobo, in Asian cooking. Roots are eaten either raw or cooked, and leaves and stems are used like spinach. Indigenous Americans were growing burdock plants in their own vegetable gardens before the country was settled by Europeans.

How to Grow Burdock

Burdock prefers loamy soil and a neutral pH in areas with average water. Seeds should be stratified and germinate at 80 to 90 % when sown directly in spring after all danger of frost has passed. Plant seeds 1/8 inch under the soil and keep evenly moist. Germination takes place in 1-2 weeks.

Once seed has germinated, young plants grow quickly but it takes some time to establish a taproot of sufficient size to harvest. Plants should be spaced at least 18 inches apart.

For the most part, burdock has no significant pest or disease issues. Continued burdock plant care is minimal but steps may have to be taken to manage the spread of the plant. Harvest leaves when young and tender and wait a year before taking the root.
