Perennial herb, medicinal, biodynamic. Fragrant flowers perfume the yard. I also make and offer a tincture of the roots. I have grown valerian here for over 25 years. I now sell the seed as well as an herbal tincture made with the roots. I use it for a nights when I have insomnia. I love the weeks when it is in flower as it perfumes the yard with a heady fragrance. It likes a moist, organic soil with afternoon shade. It will take drought after it is established.
Traditionally, Valerian flowers are used in making a a compost preparation. The roots are used herbally as well. They also attract many beneficial pollinating insects to the garden.
