Horehound
(Marrubium vulgare). A hardy herbaceous perennial, widely distributed throughout Europe and Northern Asia, and occasionally found wild in Britain. The product obtained by soaking the leaves and tops in boiling water, has long been a popular medicine for subduing irritating coughs, frequently proving effective when other and more valued remedies have failed. Horehound may be readily propagated by seeds, sown in March; by division of the roots, in spring; or by cuttings, inserted in a shady position outside. Plant about 15in. apart. Keep the ground clean between, and the roots will last several years. The annual growths may be cut when the flowers open, and dried in a cool shed, for use in winter.
