Artemisias are relatively low-maintenance plants, but they do have some preferences when it comes to growing environment. They will grow best in a full sunlocation, although most varieties can handle part shade. Most types like dry to medium-moisture soil—well-draining soil is essential. These plants are among the best at tolerating dry soil and dr...
Several popular Artemisia species are known by other common names: southernwood (A. abrotanum); wormwood, also called absinthe (A. absinthium); mugwort (A. vulgaris); sagebrush (A. tridentata); and the culinary herb called tarragon (A. dracunculus). But those used as landscape plants are often named cultivars or hybrids that are sold simply as "art...
Perennial artemisias can be cut back in the fall or spring. Shrubby varieties should be pruned back hard, to a point just above the lowest growth nodes—don't cut them back flush with ground level. Non-woody artemisias can get floppy, especially after flowering. Shear them in midsummer to prevent them from splitting open down the middle.
New plants can be started from seeds, divisions, or cuttings, but many of these plants are hybrids that are either sterile or produce seeds that do not grow trueto the parent plant. Thus, propagation is most often done by simple division of the root clumps, which offers the fastest, most trouble-free method. Here's how to do it: 1. In spring or fal...
Pure species plants will produce seeds that grow true to the parent plant but hybrids (which includes most cultivated garden plants) do not. But because simple root division is so easy, seed propagation isn't practiced very often. Even when purchasing this plant from online retailers, you will usually receive either live plants or root sections to ...
Artemisia makes a good container plant to add a gentle aroma to a sunny deck or patio. It's best to use a very porous potting mix, such as cactus/succulent mix, in a container of any material, provided it has good drainage. Standard peat-based potting mixes retain too much water and sometimes can encourage root rot with this plant. Rather than repo...
If planted in an appropriate USDA zone, artemesia needs little in the way of winter protection. In either fall or the following spring, you will want to shear back the plants to just above the growth buds (not all the way to ground level).
If the conditions are ideal, artemisias are quite resilient. Because of their strong scent, insects tend to avoid artemisias. But they can be prone to many fungal and rust diseases, like white rust, powdery mildew, and downy mildew. Hot, humid weather exacerbates these problems. Growing them in an open area with good airflow will help mitigate the ...
The tiny flowers that bloom in late summer or fall on most species are not at all showy, so lack of flowering is not considered a problem. In fact, many gardeners pinch off the flower buds to allow the plant to put its energy into growing its foliage.
These are remarkably problem-free plants, but gardeners who make an ill-advised choice of species are sometimes alarmed by the rampant spread within the garden and sometimes beyond. Generally speaking, the named cultivars are less invasive than the pure species, but some of the pure species plants can take over a garden rather easily. The biggest o...

Foliage. Deeply lobed, simple leaves (5-10 cm long, 2.5-7.6 cm wide) resemble a pinnately compound leaf with oblong, irregularly lobed 'leaflets'. The upper leaf surface is green and hairless to sparsely hairy, while the lower surface is white to grey and softly hairy.

A perennial, upright and much branched shrub that can attain a height of about 1.5 m tall if allowed to grow. Most of the white mugwort plants seen in cultivation grow as a tuft consisting of several non-flowering, low lying rosettes probably due to frequent picking for food.
