Artemisia biennis is an annual or biennial herb producing a single erect green to reddish stem up to 2 metres (6 ft 7 in) in maximum height. It is generally hairless and unscented. The frilly leaves are up to 13 centimetres (5.1 in) long and divided into thin, lance-shaped segments with long teeth. Leaves are alternate, 1-3 inches long, deeply divided into long, narrow lobes with coarsely toothed edges. Lower leaves can be double divided. Leaves and stems are hairless throughout. Stems can be simple or much branched at the base. Plants typically have a narrow, spire-like profile The inflorescence is a dense rod of clusters of flower heads interspersed with leaves. Flowers are numerous, yellow to green and globe like, 1/8 inch across in densely packed, short columnar clusters in the leaf axils, forming leafy, compound spikes on the upper stems and branches, several feet long on large specimens. The fruit is a tiny achene less than a millimeter wide.


The plant can be easily grown in a well-drained circumneutral or slightly alkaline loamy soil, preferring a sunny position. Established plants are drought tolerant. Plants are longer lived, more hardy and more aromatic when they are grown in a poor dry soil. Members of this genus are rarely if ever troubled by browsing deer.
