Whether you seek the healing properties of plants or the flavor of a fresh, wild, no-cost, caffeine-free drink, you might enjoy harvesting your own plants for tea.

In each season of the year, there are different species available for harvest. Most of them can be dried and stored for future use, and in fact, drying often improves the flavor and concentrates medicinal content. (See How to Dry Plants for Tea.)

In early spring and fall, the emphasis is usually on harvesting roots, since the energy of perennials is stored in the roots during the cold seasons. In fall, Vitamin-C-rich berries are also available. Late spring and summer bring green leaves and flowers. In winter, there are inner barks and evergreen needles.

Accurate identification, of course, is key to finding the appropriate plants and avoiding toxic species. (See Plant Identification.) Avoid harvesting plants on roadsides, under power lines, or in other places where environmental toxins might concentrate, and never take more than a quarter of the plants in a given patch of that species.

Here are just a few of the common wild plants you might want to harvest for tea.

• Burdock

Dig first-year burdock roots in the fall and second-year plants in the spring. (See Wild Edibles and Life Cycle). Burdock tea is earthy and slightly sweet, ideal for helping the body adjust to the change of seasons in spring and fall. Also good for skin problems.

• Japanese Knotweed

This invasive perennial’s roots have anti-microbial, antioxidant, and laxative properties. The flavor is much like black tea. The roots are tough and difficult to dig; stick to smallish plants with manageable roots.

• Strawberry Leaves

Mildly astringent and helpful for digestion, strawberry leaves make a nourishing, mild-tasting tea for children. Also good for diarrhea.

• Raspberry Leaves

More astringent and stronger-tasting than strawberry, raspberry leaves are full of vitamins and minerals. The tea is an excellent uterine tonic for pregnancy, lactation, and balancing the menstrual cycle. Blackberry leaves are similar.

• Peppermint

Cooling in summer, helpful for colds and fevers when drunk hot, peppermint leaves make the tastiest of teas. The plant tends to grow abundantly in damp areas and tastes best before flowering.

• Wild Marjoram

Also known as wild oregano, wild marjoram makes a relaxing tea and can also be used in cooking, like many of the mint family plants. Use both leaves and flowers.

• Wild Thyme

Yet another mint, wild thyme tea is a cold and flu remedy, and the tiny leaves and flowers can be used like domestic thyme in cooking.

• Red Clover

The blossoms make a mild-tasting tea that is full of nutrients.

• Yarrow

Yarrow flowers are somewhat bitter in taste and not for everyone. The tea is digestive, helps resolve fevers, and balances the menstrual cycle. The long basal leaves (as opposed to stem leaves) can also be used.

• St. John’s Wort

Leaves, stems, and flowers make a pleasantly astringent tea that is relaxing, with benefits for nerves and muscles.

• Staghorn Sumac

The spires of fruits on staghorn and other red-berry sumacs are full of Vitamin C when harvested in late summer. Just drop a cluster in cold water for a few hours to make a sour-tasting sumac lemonade.

• Rose Hips

The little red hips, or berries, of wild roses are easy to spot once the leaves fall off, and easy to identify because of the thorns on the stems. Crush the hips and steep them in hot water but don’t boil, in order to preserve the Vitamin C and Vitamin E.

• Hemlock or Pine Needles

Evergreen needles make a lovely, fragrant tea with tonic and antiseptic properties. (See White Pine.)

• Sweet birch bark

The inner bark of sweet birch smells and tastes of wintergreen. Rip the twigs into a pot and simmer for fifteen minutes for a tasty tea that is relaxing and remedial for arthritis.

• Mullein Leaves

Green year-round, velvety mullein leaves make a tea that treats dry coughs and asthma.
