A hardy perennial herb with fragrant pink or white flower clusters that bloom in summer, traditionally used for herbal remedies. It prefers moist, well-drained soil and tolerates part shade to full sun.

Why grow it

Common valerian is a cold-hardy perennial that establishes readily in mixed herb gardens and tolerates variable light conditions better than many medicinal herbs. Its substantial root systems can help break up compacted soil. While other Valeriana species exist, V. officinalis is the most widely cultivated in temperate regions and the species most extensively documented in herbal and horticultural literature.

Watch out for

Self-seeds prolifically once established, so deadheading spent flowers is necessary if you want to contain spread. The foliage develops a distinctly unpleasant smell when crushed or during senescence, which some gardeners find off-putting in close quarters.
