Artemisia

If you’re looking for graceful, easy-care plants to light up a sunny, dry area, look no further than Artemisia. The genus includes the ancient herbs Wormwood and Mugwort, the culinary herb Tarragon, and the plants known all over the desert West, sagebrush, are Artemisia tridentata.

Although definitely sun-loving plants, Artemisias are perfectly at home in a moon garden, where the silvery leaves catch the pale evening light. Wendy Johnson, in her book Gardening at the Dragon’s Gate, evokes their subtle magic:

“All the Artemisia plants in the garden are under the dominion of Artemis, Greek goddess of the moon and of the hunt, and guardian of the sovereign chastity of those who choose to travel in her band of solitaries. The plants of Artemis all carry her unmistakable signature: finely cut silver foliage, acrid scent, and abidingly bitter taste. All light a path through the midnight copse, welcoming night hunters home to the garden.”

Like their namesake, the solitary huntress of mythology, Artemisias prefer to be more or less left alone. As long as they are planted in a sunny spot with very well-draining soil, they require little from the gardener. A trim here and there in the summer to clean up rangy foliage and encourage a denser habit will keep them looking nice. Regular fertilizer is not necessary, but a drink of compost tea or fish emulsion once in the spring may be beneficial.

The notable fragrance of Artemisia leaves range from delightfully sweet to pungent, to a camphor-like, medicinal odor. This is due to the presence of oils and compounds which have been used for centuries in various medicinal and herbal applications. Wormwood, for instance, was known as a vermifuge, flea repellant, and bittering agent, but also as a women’s tonic and cure for sea-dragon bite (very important if you live in a maritime climate, as we do in the Pacific Northwest. Be wary of those sea dragons!).

Artemisias blend well with many different kinds of sun-loving perennials or shrubs, but especially those with similar drought tolerance, such as coneflowers, rock rose, heathers, etc. They blend especially well with blue and white tones. Try adding a Silver mound or a White Mugwort to an area planted with bright blue Lithodora and pure white Dianthus or Baby’s Breath for a lovely effect, especially at twilight.

Often referred to as sages or sagebrush, Artemisias are not to be confused with true or herbal sages in the genus Salvia.
