Roman Wormwood

Artemisia pontica is a delicate, semi-evergreen subshrub prized in UK gardens for its feathery, silver-grey foliage and aromatic properties. Reaching about 40-70cm in height, it forms a dense, spreading mound through underground runners, making it an excellent groundcover for sunny borders. This species is hardier and less woody than common wormwood, with finely divided leaves that emit a pleasant, pungent scent when brushed. In late summer, it produces inconspicuous panicles of small, nodding yellow flower heads, though it is primarily grown for its foliage. It is remarkably hardy (H6) and thrives in well-drained, even poor soils, provided it has full sun. In the UK, it is often used in knot gardens or as a textured contrast to broader-leaved herbs. It is also an essential botanical in the production of traditional vermouth. Minimal maintenance is required, though stems can be cut back in spring to encourage fresh, bushy growth.
