Russian sage (Perovskia atriplicifolia) is an attractive, low-maintenance subshrub with silvery-grey foliage and tall stems of lavender-purple flowers from late summer to early autumn. From a distance it looks like a mass of hazy blue, which deepens as it matures.
It makes a great addition to herbaceous borders and gravel gardens, and works well growing alongside other drought-tolerant plants, including eryngiums, rudbeckias and echinaceas. The flowers are a magnet for pollinating insects.
How to grow Russian sage
Grow Russian sage in full sun in well-drained soil. Prune hard each year from mid- to late spring to encourage strong, new growth that will carry flowers later in the year.
Where to grow Russian sage

How to care for Russian sage
There's very little need to water or feed Russian sage, as it's extremely tolerant of drought and thrives in poor soils. Being related to mint – which is known for its invasiveness – Russian sage can spread beyond the space you have allocated for it, so keep its growth in check by removing runners as and when you see them. Rejuvenate plants by dividing them every three to five years.
In cooler regions, Russian sage may need winter protection, although don't be alarmed if some top growth dies back – you'll be pruning this back in spring anyway.
How to prune Russian sage
Russian sage is a woody subshrub. As it flowers on new wood, cut back hard in spring to encourage new growth (and therefore flowering stems) to form. Wait for the first signs of growth, and then simply cut back to around 20cm from the ground.
How to propagate Russian sage
Russian sage can spread very slowly by runners, but the offshoots do not transplant easily. However it does divide easily, so propagate new plants by division in spring or autumn.
