Latin name
Valeriana officinalis
Common name
Valerian
Type
Medicinal perennial
Family
Caprifoliaceae

Valerian is a medicinal perennial plant highly valued for its natural habit, dissected foliage, and light bloom of small white to pinkish flowers. It brings a rustic and delicate touch to medicinal herb gardens, perennial beds, naturalized landscapes, and pollinator-friendly spaces. Its flexible and elegant silhouette adds height, movement, and a very harmonious wild aspect to the garden.

Easy to cultivate, valerian prefers a sunny or semi-shady location, in rich, fresh, deep, and well-drained soil. It appreciates regular moisture, especially during hot periods, and can form a beautiful, long-lasting clump once established. Its fragrant bloom attracts bees, butterflies, and several beneficial insects, making it an interesting plant for enriching the biodiversity of flower beds and natural gardens.

Traditionally recognized as a medicinal plant, valerian is primarily cultivated for its roots, its botanical interest, and its gentle presence in the garden. It pairs very well with monardas, skullcaps, coneflowers, grasses, yarrows, and other rustic-style perennials. It is an excellent plant for gardeners looking for a useful, hardy, and decorative perennial, perfect for a medicinal garden, a natural border, or a wild-charming landscape.
