Horehound, White (Organic)
Marrubium vulgare. Perennial in zones 3-9.
An attractive shrub with small, grey-green leaves that are covered in small white hairs, creating a fuzzy appearance. Tea can be made from the leaves and it is a favorite remedy for coughs (though it’s quite bitter so add honey). Horehound has long been noted for its medicinal qualities in treating numerous ailments. The essential oil is said to contain potent antimicrobial, antiseptic and anti-inflammatory properties. It has also traditionally been used as a flavoring for ales, sodas, and lozenges. Naturalizes easily and may spread, though germination can be slow and erratic. Best when direct sown in early spring or early fall.
Direct sow seeds very shallowly in spring, 3 weeks before last frost, or sow in flats for transplant. Germination may be slow and erratic. Thin or transplant to 10” centers. Grows well in full sun and dry, rocky ground. Perennial to zone 4. Likely to self-seed; deadhead to limit seed dispersal.
Collect seeds from seed heads that are fully dry. Thresh by hand, winnow or screen to clean. Some cross-pollination may occur, isolate from other varieties of the same species by 1/4 mile.
