Horseradish, Armoracia rusticana, is an impressive dark green herb that isgrown from root cuttings by gardeners who love the sharp, biting taste of the horseradish root. Many of us have experienced the sinus-clearing effect of horseradish! Shown here in the Arboretum's kitchen herb garden, it provides a lush, green background planting. Creeping thyme is blooming in the foreground and sweet marjoram to the left.
