A very drought-hardy silvery subshrub from Central Asia; its blue flowers from July to September give honey bees reliable nectar in late summer.
It comes from the dry, stony steppes and mountain foothills of Afghanistan, Pakistan, eastern Iran and Central Asia. Long known as Perovskia atriplicifolia, it was moved to the genus Salvia in a 2017 classification and named Salvia yangii. In Europe and Turkey it is a common ornamental in parks, road medians and dry gardens. Honey bees and wild bees visit it regularly.
Small lavender-blue flowers open on silvery stems for 8-10 weeks from July to September. Because it stays in flower even in hot, dry and sunny conditions, it bridges the late-summer dearth in unirrigated areas.
There is no monofloral honey; in urban beekeeping it contributes to mixed late-summer honeys.
It suits poor, limy and dry soils; overwatering and shade reduce flowering. Cutting it back in spring to 30-40 cm above the ground gives dense shoots with abundant flowers. Planted with lavender around the apiary, it extends the flow until the end of August.
