Artemisia arborescens, the tree wormwood, is a species of flowering plant in the family Asteraceae, native to the Mediterranean region. It is an erect evergreen perennial, with masses of finely-divided aromatic silvery-white leaves and single-sided sprays of yellow daisy-like flowers. This plant is cultivated for its foliage effects, but in colder temperate regions it requires the protection of a wall.
This plant, like others of the genus Artemisia, yields essential oils which have historically been used for various medicinal purposes, and its pharmacological properties are under investigation. It also has culinary uses, including as a substitute for or supplement to spearmint in Maghrebi mint tea during the winter (when mint is out of season), imparting a bitter flavor.
