Russian Sage

''Perovskia atriplicifolia'' , 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 tall , with square stems and grey-green leaves that yield a distinctive odor when crushed.
