Perovskia atriplicifolia
Perovskia atriplicifolia (/pəˈrɒvskiə ætrɪplɪsɪˈfoʊliə/), commonly called Russian sage, is a flowering herbaceous perennial plant and subshrub. Although not a member of Salvia, the genus of other plants commonly called sage, it is closely related to them. It has an upright habit, typically reaching 0.5–1.2 m (1 ft 8 in–3 ft 11 in) tall, with square stems and gray-green leaves that yield a distinctive odor when crushed, but it is best known for its flowers. Its flowering season extends from mid-summer to as late as October, with blue to violet blossoms arranged into showy, branched panicles.Native to the steppes and hills of southwestern and central Asia, it was introduced to cultivation by Vasily Perovsky in the 19th century. Successful over a wide range of climate and soil conditions, it has since become popular and widely planted. Several cultivars have been developed, differing primarily in leaf shape and overall height; 'Blue Spire' is the most common. This variation has been widely used in gardens and landscaping. P. atriplicifolia was the Perennial Plant Association's 1995 Plant of the Year, and the 'Blue Spire' cultivar received the Award of Garden Merit from the Royal Horticultural Society.The species has a long history of use in traditional medicine in its native range, where it is employed as a treatment for a variety of ailments. This has led to the investigation of its phytochemistry. Its flowers can be eaten in salads or crushed for dyemaking, and the plant has been considered for potential use in the phytoremediation of contaminated soil.
