Did you eat Horehound candy when you were a child? You may not have known it, but your parents were actually giving you "medicine"! Candy made from the herb Horehound was often given as a cough drop to sooth deep chest coughs.
Grow the Horehound herb plants in any well-drained soil in full sun. Keep cutting back for new flushes of growth and extended harvests. The leaves and flowers lose their flavor quickly, so snip them into smaller pieces to dry on screens. When dry, crumble and store in jars. Cut the flowers and harvest it heavily each season as this plant is a liberal self-sower, dropping its own Horehound seeds and spreading.
A perennial plant for zones 4-8, growing 18-24" tall.
