Overwintering Perennial Tea Herbs Outside and in Containers Without Winter Kill

As autumn nears, gardeners focus on prepping their gardens for frosty winter weather. But if your herbs need overwinteringing, it may not always be necessary to bring them inside for protection.

Hardy perennial tea herbs typically thrive in containers provided they receive plenty of light. Fill pots with potting mix and aged compost to enhance soil porosity and drainage.

Thyme

Many perennial herbs can survive outside during the winter and will rebloom or self-seed in spring, including thyme, tarragon and certain varieties of rosemary as well as chives, oregano and basil.

These herbs thrive best in full sunlight and prefer dry, well-draining soil. Plants should be kept slightly warmer than optimal, watered regularly but not overwatered, and shade can provide valuable respite during hot summer days.

Marjoram

Chives, members of the onion family (Allium), are hardy enough to thrive in Zone 4, becoming dormant during winter but quickly returning in spring. Preferring full sun or partial shade conditions and light, well-draining soil conditions, these beautiful perennial plants thrive year-round!

Marjoram belongs to the origanum family of herbs, and closely resembles oregano in terms of medicinal uses. Marjoram can help support digestive health while relieving respiratory congestion; its antiseptic, antimicrobial and antifungal properties as well as expectorant properties can relieve phlegm buildup.

Good-King-Henry

Good-King-Henry (Chenopodium miliaceum) is a perennial spinach variety hardy in USDA zones 3-9. This low maintenance herb produces edible leaves and shoots throughout the summer season as well as edible seeds and flowers, although beware that all parts contain high concentrations of oxalic acid – consume them responsibly!

Reduce watering with the soil touch test as a gauge for moisture level. Add an insulating mulch layer such as weed-free straw, bark chips or pinestraw. Finally, move herbs to an area protected from frost during winter.

Sweet Cicely

Perennial herbs are an ideal addition to any gardener’s portfolio, offering steady harvests year after year without needing constant replanting. Plus they’re low-maintenance and easy to cultivate even for beginners!

Salad burnet may look innocuous in your garden, but this hardy perennial makes a tasty addition to salads and soups. It thrives both under partial shade and full sunlight conditions and thrives in many types of soil conditions; its flowers also make an elegant accent piece in any flower garden.

Lovage

Lovage plants are straightforward to cultivate in full sun conditions. Plant seeds either directly into your garden during autumn or spring planting season or indoors 6-8 weeks prior to their frost date.

Lovage leaves, stalks and seeds all add an irresistibly celery flavor to soups, salads and stews, while its high quercetin content helps ease cold and allergy symptoms.

Mulch lovage plants that have become established in the ground every spring by spreading a thick layer of organic matter over their clump, to enrich soil and minimize evaporation. This will also improve air quality.

Lemon Balm

Lemon balm (Melissa officinalis) is another evergreen herb that thrives in zones 5-9, making it an excellent addition to homemade herbal tea blends or salads, fish dishes or adding subtle citrus notes into homemade lemonades.

Long utilized as an herbal medicine, passionflower has long been sold to help treat sleeplessness. Prefers full sun and soil that drains well – ideal conditions would include moist soil with adequate drainage.

Lime Balm

Like its cousin mint, lemon balm can grow aggressively in gardens if left alone. To control its spread, plant it in containers or indoors where its growth can be monitored with ease.

Herbal allies like passionflower can provide quick-relief remedies for anxiety and nervous stomach ache. By helping to balance the hypothalamic-pituitary-adrenal axis, passionflower helps ensure an efficient “fight or flight” response when necessary in potentially life-threatening situations.

Craft a refreshing cup of tea using this herb to energize yourself in the morning or aid your sleep and digestion in the evening, and enjoy an aromatic herbal bath experience! It is also excellent as a stress relief agent!

Lavender

Lavender has long been recognized for its sedative and anxiolytic effects as well as its anti-inflammatory benefits, in addition to possessing strong antimicrobial and antifungal properties in its volatile oils. It’s no secret that lavender’s medicinal uses include its many therapeutic qualities; all this and much more have been well documented!

Lavandula angustifolia ‘Grosso’ culinary lavender is an indispensable component of herb blends such as Herbes de Provence. Producing fragrant dark blue flower spikes on long stems, its distinctive dark blue blossoms add fragrance to any recipe for creating tasty meals.

Hidcote Giant and Munstead varieties also thrive, being hardy in zones 8-11.
