  • Leaves may be harvested once the plant is established and at least 6 inches tall; the plant flowers and produces seeds in the second growing season that may be harvested and dried
  • The seeds may be added to flavor duck, chicken, goose and pork dishes as seeds or ground to a powder to flavor meats, young leaves may be added to salads to add a light licorice flavor or the tap root roasted and cooked as you would any autumn root vegetable
  • Health benefits from the caraway plant include vitamins C, A, E and B complex, carotenoids and magnesium, which help improve your digestion, sleep quality and lower inflammation

Caraway (Carum carvi) is an aromatic herbaceous plant, but is better known for their seeds. The origins of the name come from the Arabic "al-karwiya" seeds. Others believe the origin of the name is Latin from the word carvi, originating from Caria where the caraway plant may have first been used.1

Growing caraway requires some patience as the plant is biennial.2 This means the plant has a two-year biological cycle. In the first year, it produces a root structure, stems and leaves. During the second growing season, the plant completes the formation of flowers, fruit or seeds. Following the second season, many will reseed and then the plant usually dies. Most biennials are vegetables.

Caraway is usually grown for its intensely scented seeds or as a parsnip-like root vegetable.3 It is hardy, growing to about 8 inches in the first year with finely divided leaves and a long taproot. By the second year, the stalks grow up to 36 inches and develop white or pink flowers appearing between May and August.

Caraway seeds are often added to breads, cakes, soups and cabbage dishes to add a pungent flavor. By some accounts, it's the oldest known condiment and was once a key ingredient in love potions.

History of Caraway Dates to the Stone Age

Archaeologists have dated the plant to the Stone Age and it has also been found in Egyptian tombs. The first century Greek physician Dioscorides used it to make a tonic to restore the color in the cheeks of those with pale complexions. Julius Caesar's favorite bread was made with caraway seeds and it was a favored medicine in ancient civilizations of Egypt, Persia and Greece.4

Caraway was first introduced in England in the 14th century in a cookbook compiled for King Richard II. Later it was eaten at the end of a meal to cleanse the palate. William Shakespeare helped popularize this practice in a scene from Henry IV when, in an invitation to Falstaff, he was invited to5 "partake of a pippin … with a dish of caraway."

German, Austrian, Dutch and Eastern European cooks tend to use the herb to balance fatty meats like duck and goose. Caraway also has a history of use outside the kitchen as Egyptians reportedly buried their dead with the plant to ward off evil spirits, or to protect against theft. The ancient Greeks used it in cosmetic solutions and as a light sedative.6

In German folklore, caraway seeds were placed beneath children's beds to ward off witches. It was also added to chicken feed in the hopes it would keep the animals from wandering off. Today, it is still sometimes given to homing pigeons.7

How to Plant Caraway

The caraway plant is a cool-season biennial,8 doing best in sun or partial shade in zones 4 through 10.9 In cooler zones, the plant appreciates full sun, while in warmer zones it needs partial shade during the heat of the afternoon sun.

Since the caraway plant has a long tap root, it doesn't do well in small containers. If a container garden is your choice, be sure the pot is at least 8 in deep — the deeper the better. Prepare your soil with organic matter and keep the pH between 6.0 and 7.5.10

Caraway plants should be sown either in the spring or autumn. In the springtime, plant the seeds after the last frost. For an earlier start, consider planting indoors in a tray. However, ensure you transplant the plants to the garden before the root appears, as it is easily damaged.11

Caraway can also be started from seed in the fall for early spring plants. If planting in the fall, give them winter protection so they produce flowers and seeds in the second year. Additionally, the plant can be started from cuttings of new growth taken in the summer or fall.

Sow the seeds one-fourth inch deep and then thin the seedlings to 12 to 18 inches apart. The plants appreciate moist soil without developing a water log in the roots. They do not like humidity, however, so don't use overhead watering.12 Fortunately, the plant is not usually affected by insects. Foliage challenges may be prevented by allowing the leaves to dry between watering.13

Harvest Your Caraway Seeds and Store for the Future

The leaves of the plant can be harvested from spring onward once the plant is well-established and at least 6 inches or taller.14 Use them immediately in fresh salads or dry them on a flat tray and store in an airtight container for flavoring later. In this way, they can last for up to a year.

The seeds should be harvested once they appear on the plant and develop a deep brown color. To do this, cut the seed heads, including a fairly long stalk, using shears or a sharp knife to avoid damaging the plant. If you leave the seed head in the garden too long, the plant will reseed the garden in a good stiff wind.15

Tie a piece of muslin or paper bag around the seed head and hang the stems upside down to allow the plant to continue to ripen. When the seeds are ready, they'll fall out of the seed head and into the bag or muslin.

Fresh seeds can be replanted immediately, or they can be placed on a fine-mesh to dry for several days and then stored in an airtight container to be used in the kitchen.16 Once you harvest your seeds, consider digging up the tap root and using it as you would any other root vegetable, cutting it and cooking soups or stews.17

Numerous Potential Health Benefits of Caraway

The plant is easy to grow, care for and harvest in your own garden, giving you easy access to an excellent source of potassium and calcium. Caraway also contains powerful antioxidant phytochemicals, the most prevalent of which are the carotenoids lutein and zeaxanthin, which help neutralize and remove free radicals and prevent degenerative diseases.

Caraway is also high in fiber and contains vitamins C, A, E and B complex. Adding the leaves, seeds and root and to your regular diet can be beneficial to your health in a number of ways. For instance caraway may help:18,19

  • Promote digestive health — A 100-gram serving of caraway seeds provides 38 grams of fiber,20 a dietary component that helps maintain proper digestive health promoting regularity and helps reduce your risk of stomach and intestinal diseases.
  • Fight microbes — Caraway essential oil has antibacterial properties, and has been found to help inhibit harmful organisms like salmonella.21
  • Manage inflammation — According to Organic Facts, taking caraway oil with raw honey or warm water may help loosen up mucus in the respiratory system as well as control the inflammation in the airways.22 Even smelling the powerful oil may help break up congestion from coughs and colds and provide relief for those with bronchitis.
  • Improve sleep quality — Magnesium, a mineral found in caraway seeds, may help enhance the duration, quality and tranquility of sleep, leaving you feeling better for the next day.

Don't Overlook the Benefits From Caraway Essential Oil

The essential oil from the caraway plant has been used in manufacturing processes, such as for flavor in certain medications or fragrances for soaps and toothpaste. Caraway oil is also used in aromatherapy and appreciated for its warming and stress-relieving properties.

Caraway oil promotes skin and hair health as it is an effective tissue regenerator. Some find it helps fight oily skin, clear acne and heal bruises and boils. The oil has antiseptic, antihistamine, antispasmodic, digestive and disinfectant properties making it beneficial for23 treating or alleviating indigestion, heart ailments, urinary issues and internal infections.

The oil is made from distilling the seeds of the plant and is usually used topically or inhaled. Try diffusing it in a burner or vaporizer, blending it with massage oil or adding it to a cream or lotion.

While generally safe for most, I do not recommend it for pregnant women as it can induce menstruation. I advise you do a sensitivity test on a small area before applying generally or using it in a vaporizer or inhaler. Apply a drop of diluted oil to the inner aspect of your elbow and observe for a reaction over 24 hours.

Skin irritations, such as rashes and itching may occur when you use the oil high concentrations even if you do not have an allergy to the oil, so be sure to dilute it with a safe carrier oil before applying it on your skin.

Cooking With Caraway

Caraway has an aromatic, sweet taste with a licorice flavor that adds richness to your dishes. Caraway seeds make for an interesting twist when making sauerkraut and the roots may be added to a pan of roasted autumn vegetables. The leaves may be added to salad as a flavor herb.
