Artemisia arborescens (tree wormwood) is a species of flowering plant in the family Asteraceae, native to the Mediterranean region.[2] 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.

The specific epithet arborescens means "woody" or "tree-like".[3]

This plant[4] and the cultivar 'Powis Castle'[5] have gained the Royal Horticultural Society's Award of Garden Merit.[6]

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.[7][8]
