What Is Valerian?

Valerian is a tall perennial herb traditionally valued for its calming properties and long history of use in herbal medicine. Native to Europe and parts of Asia, it’s best known for its strongly scented roots and clusters of pale pink or white flowers.

In the garden, valerian is hardy, low maintenance, and long lived. It’s often grown specifically for its roots, which are harvested after the plant has fully matured, making it a rewarding herb for patient gardeners.

Growing Conditions

Sunlight Requirements

Valerian grows well in full sun to part shade. In warmer regions, some afternoon shade can help reduce stress.

Soil & Drainage

Moist but well-draining soil is ideal. Valerian prefers rich soil and benefits from compost additions but does not tolerate waterlogged conditions.

Watering Needs

Consistent moisture is important, particularly during establishment. Once established, valerian still prefers evenly moist soil.

Temperature & Frost Tolerance

Valerian tolerates cold conditions and frost. Growth may die back in winter and reappear in spring.

How to Plant Valerian

When to Plant in Australia

Valerian is best planted from spring through early summer, depending on your climate zone.

Sowing Seeds

Seeds are best started as seedlings. Sow seeds around 4 mm deep and keep soil consistently moist until germination.

Germination & Early Growth

Seeds typically germinate within 7–14 days in warm conditions. Seedlings establish steadily and benefit from protection from extreme heat.

Transplanting & Spacing

Space plants around 60 cm apart to allow for mature size and airflow.

Ongoing Care & Maintenance

Watering Once Established

Water regularly during dry periods. Valerian does not tolerate prolonged drought.

Feeding & Soil Health

Apply compost annually to support healthy growth and root development.

Pruning & General Maintenance

Flowers can be deadheaded to reduce self-seeding or left to attract pollinators. Cut plants back at ground level in late winter.

Common Pests & Growing Issues

Common Pests

Valerian is generally pest resistant. Slugs and snails may occasionally affect young plants.

Diseases & Fungal Issues

Fungal issues can occur if soil is waterlogged or airflow is poor. Ensure good drainage and spacing.

Environmental Problems

Dry soil can limit root development. Consistent moisture is key to healthy plants.

Companion Planting

Good Companion Plants

Valerian grows well alongside other perennial herbs and flowering plants. It pairs well with echinacea, yarrow, lemon balm, and anise hyssop.

Plants to Avoid

There are no major companion conflicts, though valerian’s height may shade smaller plants.

Harvesting Valerian

When to Harvest

Roots are typically harvested in autumn after plants are at least two years old. Leaves and flowers can be harvested earlier if required.

How to Harvest Different Plant Parts

  • Roots:Β Lift carefully, wash thoroughly, and prepare for drying
  • Leaves:Β Harvest sparingly during the growing season
  • Flowers:Β Cut when fully open

Traditional Medicinal Uses of Valerian

Valerian has a long history of use in traditional herbal medicine, particularly for promoting relaxation and supporting sleep. The roots contain aromatic compounds that have traditionally been prepared as teas or tinctures.

Valerian was also used historically to ease nervous tension and restlessness. These uses are based on traditional practice rather than modern medical claims.

How to Use & Prepare Valerian

Making Herbal Tea

Dried valerian root can be brewed into herbal tea, traditionally taken in the evening.

Tinctures & Extracts

Valerian is commonly prepared as a tincture using dried or fresh roots for longer-term storage.

Oils, Salves & External Uses

External use is less common, with valerian primarily used in internal preparations.

Drying, Storing & Preserving

Drying Methods

Roots should be chopped and dried thoroughly in a warm, well-ventilated area away from direct sunlight.

Storage Tips & Shelf Life

Store dried roots in airtight containers in a cool, dark place. Properly dried valerian stores well for many months.

Is Valerian Right for Your Garden?

Valerian is an excellent choice for gardeners wanting to grow a traditional medicinal herb with a long history of use. While it requires patience to harvest, its resilience and reliability make it a valuable addition to home medicinal gardens.
