Wormwood sometimes referred to as mugwort, is a member of the Artemisia genus which is grown for its foliage and filigree-like leaves. The plant can be grown in herb gardens as well as in containers. It should be grown in full sun and watered every 2 to 3 weeks once fully established. The plant is often used in various essential oils and can be used as a natural pesticide by making wormwood tea. However, the pesticide should not be used on edible plants.
