The Story
Plant Bio
Valeriana officinalis, commonly known as valerian, is an upright, clumping herbaceous perennial native to Eurasia, reaching heights of three to five feet. The pinnately compound leaves feature lance-shaped, toothed leaflets that emit a strong, musky scent when bruised, while dense terminal clusters of tiny, sweetly fragrant white to pale pink flowers open in summer.
This baseline species spreads via short rhizomes and stolons to form robust, leafy clumps that bring a wild, naturalistic texture to moist borders. While selected medicinal strains may yield higher root biomass, the standard species provides the classic garden form with reliable flowering and vigorous growth.

Planting
How to Grow
- Plant in a full sun position with rich, moist, well-drained soil to encourage strong, upright stems.
- Water regularly during dry spells to maintain consistent soil moisture, as the shallow root system suffers quickly in dry conditions.
- Cut the entire plant back to ground level in late fall or early spring before new shoots emerge.
- Divide overcrowded clumps every three to four years in early spring to maintain vigor and control spread.
Pro Tip
Deadhead the spent flower spikes immediately after blooming to prevent aggressive self-seeding, and avoid over-fertilizing, which causes the tall stems to become weak and flop.

Care Guide
Do
- Deadhead spent flowers promptly to control self-seeding.
- Provide light afternoon shade in hot-summer regions to prevent leaf scorch.
- Wear gloves when handling roots or foliage if you have sensitive skin.
Don't
- Do not apply heavy nitrogen fertilizers, which stimulate weak, floppy growth.
- Do not allow the soil to dry out completely during the active growing season.
- Do not plant in poorly drained, stagnant sites where water pools.
