Artemisia longifolia is a perennial up to 80 cm (32 inches) tall, usually not forming clumps. Leaves are longer and narrower than for most related species, up to 12 cm (5 inches) long. The species grows in barren areas, in grasslands, and in alkaline flats in the high plains.^[3] It is completely deciduous unlike many related species in Artemisia.^[4]

Cultivation

Considered a handsome plant by gardeners such as the author Claude A. Barr for its foliage and also for the very pleasant scent of its foliage when brushed against or crushed. It is relatively well behaved in the garden, not seeding as freely as some other Artemisia species and only being somewhat rhizomatous.^[4]
