It has an upright habit, typically reaching 0.5–1.2 metres (1+1⁄2–4 feet) tall, with square stems and gray-green leaves that yield a distinctive odor when crushed. It is best known for its flowers.

It is a shrub or small tree typical of littoral zones reaching a height of 3.6 m (12 ft), with a spread of about 5 m (16 ft).

Salvia subgenus Perovskia is a group of species within the flowering plant genus Salvia, which prior 2017 were treated as the separate genus Perovskia. Members of the group are native to southwestern and central Asia. It includes the garden plant Russian sage (Salvia × floriferior).

Cercidoideae is a subfamily in the pea family, Fabaceae. Well-known members include Cercis (redbuds), including species widely cultivated as ornamental trees in the United States and Europe, Bauhinia, widely cultivated as an ornamental tree in tropical Asia, and Tylosema , a semi-woody genus of Africa. The subfamily occupies a basal position within the Fabaceae and is supported as monophyletic in many molecular phylogenies. At the 6th International Legume Conference, the Legume Phylogeny Working Group proposed elevating the tribe Cercidae to the level of subfamily within the Leguminosae

The subfamily Dialioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees and shrubs. The subfamily consists of 17 genera, which are widespread throughout the tropics. It has the following clade-based definition: The most inclusive crown clade containing Poeppigia procera C.Presland Dialium guianense (Aubl.) Sandwith, but not Cercis canadensis L., Duparquetia orchidacea Baill., or Bobgunnia fistuloides (Harms) J. H. Kirkbr. & Wiersema Members of the family also share the following morphological characteristics: the presence of
