Russian sage

Sun

Full sun; shade produces weaker stems and fewer flowers.

Water

Water regularly during the first growing season, letting the soil dry between waterings. Established plants need little supplementary water except during prolonged drought.

Soil

Well-drained sandy, gravelly or loamy soil, including poor and chalky soils. Avoid ground that stays wet in winter; drainage matters more than fertility.

Height

3-5 ft (0.9-1.5 m)

Spread

2-4 ft (0.6-1.2 m)

Flowers

Small violet-blue flowers in branching sprays from midsummer into autumn.

Foliage

Deciduous, finely divided grey-green leaves on pale, silvery stems; strongly aromatic when rubbed.

Growth

Moderate to fast once established.

Care needed

Low

• Plant in full sun with the crown at soil level, not buried.
• Water deeply during establishment, then allow the soil to dry before watering again.
• Avoid routine feeding; rich soil and nitrogen fertiliser encourage floppy growth.
• Use a thin gravel mulch rather than piling damp organic mulch against the crown.
• If support is needed, fit discreet stakes early; persistent flopping usually signals too much shade, water or fertility.

Pruning. In spring, once buds begin to swell and severe frost has passed, cut stems back to about 6-12 in (15-30 cm), retaining healthy low buds where present. Remove dead stems and leave the top growth standing through winter rather than cutting it down in autumn.

Spring

Cut back old stems as low buds begin to grow; allow time for this late-starting plant to wake up.

Spring

Plant in cold-winter regions, choosing a sunny position with excellent drainage.

Early summer

Check new plants for dry soil and add discreet support before stems lean, if needed.

Summer

Take softwood cuttings from healthy, non-flowering shoots.

Late summer

Water established plants only if prolonged drought is causing persistent wilting.

Autumn

Leave flower stems standing for structure and clear fallen debris away from the crown.

Winter

Check that water drains away from the crown, especially in heavy soil or containers.

• Plant in repeated groups through a sunny border to create a haze of blue above lower plants.
• Combine with ornamental grasses and coneflowers for a loose, late-season planting.
• Use beside gravel paths or paving, allowing enough room for the stems to arch without blocking access.
• Pair with yellow yarrow or orange-flowered perennials for a strong colour contrast.
• Place behind lavender or low stonecrops in dry borders to add height without a solid visual barrier.

Garden styles it suits: Dry gravel garden, New perennial (prairie), Mediterranean, Cottage garden, Pollinator garden and Desert / xeriscape.

Plant it with: Purple coneflower, Yarrow, Feather reed grass, English lavender, Butterfly weed and Autumn stonecrop.

Wildlife: Flowers provide nectar for bees and other pollinating insects. Aromatic foliage is usually avoided by deer and rabbits, although no plant is completely browse-proof.

• Crown or root rot in wet soil: improve drainage or move the plant to a raised, freely draining position; reduce watering.
• Flopping stems: provide full sun, stop nitrogen feeding and avoid frequent watering; support existing stems if necessary.
• Winter dieback: leave stems standing until spring, then remove dead growth; avoid wet sites and exposed containers in cold regions.
• Unwanted suckers: remove shoots with their attached roots in spring to keep the clump within bounds.

Russian sage is not known to be toxic to people, cats, dogs or horses, although species-specific information is limited, particularly for horses. The leaves, stems and flowers are not culinary sage and should not be treated as food; discourage chewing or eating them.

• Catmint (Nepeta × faassenii)

  Catmint usually forms a lower, denser mound with broader, scalloped leaves; Russian sage has taller, pale woody stems and more finely divided foliage.

• English lavender (Lavandula angustifolia)

  Lavender has narrow, undivided leaves and compact flower spikes; Russian sage has divided leaves and open, branching flower sprays.

• Bluebeard (Caryopteris × clandonensis)

  Bluebeard has broader, toothed leaves and blue flowers clustered near the leaves along the stems, rather than Russian sage's long, airy sprays.

Salvia comes from the Latin salvere, meaning 'to be well', referring to the traditional medicinal use of some sages.

Propagation. Take softwood cuttings in late spring or early summer, or detach rooted suckers in spring. Seed is possible, but named cultivars may not come true from seed.

Accepted botanical name

Salvia yangii

Native range

Afghanistan, Pakistan, Tibet, West Himalaya and Xinjiang.
