Valerian produces, from a basal clump of feathery foliage, hollow flower stems with high bearing flat-topped clusters of tiny pale pink fragrant flowers that smell rather like heliotrope all summer. Attractive to many fly species which can help with pollination in the garden.The leaves and strong-smelling root, when disturbed is attractive to cats, like Catnip.This variety should not be confused with the False Valerian or Red Spur Valerian, Latin name Centranthus rubra.Sowing Valerian Sow seed from spring through to summer into trays to start off with. Lightly cover with fine soil and keep evenly moist during germination. Once germinated transplant seeds into the ground. Seedlings establish best in a sunny position. Valerian is considered a weedy or potentially invasive herb in New Zealand, so growing in containers or pots to prevent the spread is advised.Harvesting Valerian Roots are typically best lifted in autumn once plants have matured. Wash thoroughly and dry in a warm, airy space before storage. Leaves and blooms can be gathered during summer for ornamental or herbal use.Uses of ValerianMedicinally, Valerian is grown for its roots, which are dried and used for teas and tonics and was popular in Victorian times as a sleeping draught used for treating insomnia. It is commonly sold as a dietary supplement to support sleep and relieve mild nervous tension, but there is insufficient evidence from clinical studies to support this.Medicinal use of herbs requires thorough research. We advise checking with a medical professional, particularly if pregnant, breastfeeding or on medication.
