Horehound

(Marrubium vulgare) Horehound is native to Europe, northern Africa, and southwestern Asia and now naturalized in the Americas. This mint family relative is perennial from USDA hardiness zones 4-10 and has been enjoyed by gardeners and herbalists since antiquity. Horehound grows best in full sun and requires minimal care. Seeds germinate in 14-21 days. Ideal germination temperature is 86-75F. Start plants in containers, covering the seeds very lightly and keep them moist until sprouts appear, then set the plants out after the last frost of spring. Cutting back plants in autumn helps keep them vigorous and tidy. Plants require full sun and prefer a well-drained, somewhat dry soil. Space plants 10-12 inches apart. Like all mints, horehound does have the potential to take over, so treat it as you would other mints and plant in a pot or in a designated section of the herb bed.
