The bluish haze aspect of Perovskia 'Blue Haze' works wonders in rock or Mediterranean gardens without watering. In a sunny bed, it pairs perfectly with pink or red shrubby sages ('Rêve Rouge', 'Royal Bumble', 'Cerro Potozi', 'Icing Sugar') and light grasses like Chinese fountain grasses. In a scene that is both structured and soft, pair it with other Mediterranean plants in a blue-mauve colour scheme, such as Lavandins or Nepetas, to create a summery scene full of freshness and movement.
The genus name Perovskia pays homage to the Russian general V. A. Perovski, while the epithet "atriplicifolia" means "with leaves like Atriplex"; the accepted specific name "yangii" honours the Chinese botanist Chang-you Yang.
Despite its common name, "Russian sage" is not native to Russia; it was introduced to the United Kingdom in the early 20th century and popularised for the "haze" effect of its inflorescences from a distance.
