Black horehound plants thrive well in moist, nutritionally poor and well-drained soil. Black horehound possess the aptitude to grow well in sunlight as well as shade.

The generic name of the plant Ballota has been derived from geek ballo, which denotes getting rid of or throwing away. The name seems to be apt for the herb, as black horehound emits a very potently disagreeable smell - repulsing people and animals. The specific name ‘nigra’ has been derived from the Latin term ‘nigrais’, meaning “black”. It is important to note that you should not confuse this plant with another species called white horehound, whose actions are dissimilar.

Precisely speaking, the black horehound is a perennial plant having a potently offensive smell. The whole plant has an unpleasant odour and its leaves release a horrible smell when they are bruised or crushed. The odour is similar to that of stale sweat.

Black horehound plants have a preference for growing in areas receiving full sunlight or those in partial shade. While growing in the wild, black horehound keeps away from acidic soils, but, when cultivated, black horehound possesses the aptitude to endure low pH levels up to 5. Although the black horehound is a very resilient plant, black horehound is not so hardy when grown in colder regions. However, black horehound can endure temperatures as low as -5ºC to -10ºC. While black horehound is cultivated extensively in herb gardens, black horehound is rarely used, as black horehound has a potently disagreeable flavour and odour.

The essential oil obtained from black horehound plants is used for adulterating the oil extracted from another horehound species called white horehound (botanical name Marrubium vulgare). The leaves of black horehound release a horrible smell when they are crushed or bruised - an odour akin to stale sweat. In fact, the entire black horehound emits a potently disagreeable smell. Plants belonging to this species possess the ability self-sow readily, provided the growth conditions are suitable. Often, gardeners cultivate a particular named variety for its ornamental worth.

Black horehound is generally propagated by its seeds, which are sown in a greenhouse either in spring or autumn. Normally, the seeds begin to germinate within three to six weeks from the day of sowing, provided the temperature is maintained at 15ºC. When the seedlings have grown to a reasonable height, they need to be pricked individually and transplanted into separate containers or pots. They can be planted outdoors into their permanent place either during the summer or in the next autumn.

Plants of this species may also be propagated by root division, ideally undertaken during spring. While you can directly plant the comparatively large divisions outdoors in their permanent place of growth, the smaller divisions or clumps should preferably be grown in pots in a cold frame till they are established.
