Sometimes called mugwort, wormwood (Artemisia absinthium) is a woody perennial sub-shrub noted for its fragrant, silvery foliage and tolerance for poor growing conditions. It grows best within U.S. Department of Agriculture plant hardiness zones 4 to 9, where it is widely used as an ornamental foliage plant in xeric, or low-water, landscaping. Wormwood requires minimal upkeep or care once established in a sunny site with fast-draining soil. However, the plants will look better and live longer if watered occasionally during the summer months and pruned periodically to refresh their foliage
It can be invasive in the US.
