Description

The Artemisia genus is a member of the aster family (Asteracea) and contains approximately 300 species of herbaceous annual, biennial, and perennial plants found throughout temperate regions of the Northern Hemisphere, South America and South Africa.  Artemisia species inhabit sunny, dry, infertile soils.  Suitable climates support growth of wild or naturalized species as well as those cultivated for ornamental use.  This diverse species varies greatly in size and shape, ranging from soft fern-like to erect shrub-like forms.  Most have herbaceous or woody stems with clumping, mounding or ground-hugging growth habits.  Plants spread primarily through rhizomatous roots.  Small inconspicuous yellow-white flowers may also produce viable seeds.  In the northern U.S., some species may become weedy in disturbed areas.  Many perennial species have been cultivated for ornamental garden use in USDA Zones 3-8.  This species is most noteworthy for its aromatic foliage and/or interesting texture.   Leaves, ranging in color from green to silvery gray, may be finely cut and covered with velvety hairs.   Silvery foliage offers a soft color to complement or contrast with other landscape plants.  Leaves of many species contain thujones, terpenoids, and other chemical compounds that contribute to its fragrance.  Depending on the species, these compounds also have potential for toxicity in humans, pets, and livestock.  Some species have been used for herbal or culinary purposes.  Leaves of some species remain fragrant long after they are cut and dried, making them desirable for use in sachets, floral arrangements, and potpourris.  Its strong aroma and taste generally discourage garden herbivores and some insects.  They will not tolerate wet soils, wet winter conditions, or climates with high humidity.  Plants are prone to rot in moist conditions.
