Garden heliotrope, also known as common Valerian and All-Heal, is a clumping perennial with scented leaves, stems, flowers and roots. It is native to Europe and western Asia, but has escaped gardens and locally naturalized in the northern U. S. and Canada.
This medicinal herb crosses the herb garden paradigm and looks great situated in a border.
It typically grows in damp locations, but also can be found in drier soils. It often naturalizes along roads or in fields.
Leaves are aromatic when bruised. Strong-smelling roots yield the drug valerian which has been used for many years in herbal medicines for treating a large number of problems including anxiety, restlessness and insomnia. Extracts have also been used in perfumes, herbal teas and for flavoring in a variety of food products. Plants are cultivated in Europe today for producing an over-the-counter tranquilizer. Genus name comes from Latin valere (be strong and healthy) and the specific epithet means medicinal, both in reference to herbal/medicinal uses.
Transplant when there are at least two sets of true leaves. Space 60-90 cm apart, preferably in partial shade, but it will tolerate full sun.
Site in a moist, well-drained soil. Keep plants evenly moist: neither allow them to dry out nor to sit in water-logged soil.
Plants will spread underground via rhizomes and may need dividing in late fall or early spring.
The tall plants may require staking, especially when in flower.
