Salvia yangii
Salvia yangii, previously known as Perovskia atriplicifolia, and commonly called Russian sage, is a flowering herbaceous perennial plant and subshrub. It has an upright habit, typically reaching 0. 5–1. 2 m tall, with square stems and grey-green leaves that yield a distinctive odor when crushed. Its flowering season extends from mid-summer to late October, with blue to violet blossoms arranged into showy, branched panicles.
About Salvia yangii in brief
Salvia yangii, previously known as Perovskia atriplicifolia, and commonly called Russian sage, is a flowering herbaceous perennial plant and subshrub. It has an upright habit, typically reaching 0. 5–1. 2 m tall, with square stems and grey-green leaves that yield a distinctive odor when crushed. Its flowering season extends from mid-summer to late October, with blue to violet blossoms arranged into showy, branched panicles. S. yangii 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. Its flowers can be eaten in salads or crushed for dyemaking. The plant has been considered for potential use in the phytoremediation of contaminated soil. It is native to the steppes and hills of southwestern and central Asia, and has since become popular and widely planted. Several cultivars have been developed, differing primarily in leaf shape and overall height, the most common of which is Blue Spire, which has been widely used in gardens and landscaping. The foliage is aromatic, especially when crushed, with a fragrance described as sage-like, a blend of sage and lavender, or like turpentine.
The inflorescence is a showy panicle, 30–38 cm long, with many branches. Each of these branches is a raceme, with the individual flowers arranged in pairs called verticillasters. The corolla is tube-shaped, formed from a four-lobed upper lip and a slightly shorter lower lip. The style has been reported in both an exserted—extending beyond the flower’s tube—form and one contained within the flower; all of the known examples of S. Yangii in cultivation have exsERTed styles from a distance of the flowers from a fine haze or fog. Fruits develop about a month after flowering, and consist of dark brown ovalnut-shaped nutlets, about 2mm × 2mm. S.yangii can be as long as June through October, although populations in some parts of its range, such as China, may bloom in a much more restricted period. Superficially, it resembles a much larger version of lavender. The specific epitotype of the species’s holotype is the species’s holotype as the holotype of herbarium atripticifolium, which means ‘with saltbush’, referring to its similarity to saltbush, or ‘sage’. While commonly known as Russian Sage, it was originally referred to as ‘Perovski’ by George Bentham in 1848.
