Perovskia atriplicifolia

Perovskia atriplicifolia: Azure Drift of Summer

Airy and architectural, Perovskia atriplicifolia, or Russian sage, brings a cloud of lavender-blue blooms to the garden from midsummer well into fall. Its finely divided, silvery-green foliage releases a light, herbal scent when brushed, adding a sensory dimension to its visual appeal. Tall, branching stems remain upright and graceful even in heat and drought, creating a haze of colour that softens the edges of sunny borders while drawing in bees, butterflies, and admiration from all who pass.

Plant Characteristics:

• Height: 90–120 cm
• Spread: 75–90 cm
• Flower Colour: Lavender-blue
• Flowering Period: Mid to late summer through fall
• Foliage: Silvery-green, finely cut, aromatic
• Sunlight Requirements: Full sun
• Soil Requirements: Well-drained, sandy to average soil; drought tolerant

Uses and Benefits: Perovskia atriplicifolia is a must-have for drought-tolerant plantings, pollinator gardens, and borders that need long-lasting colour and structure. Its open, bushy form contrasts beautifully with bolder perennials, while its resilience in poor soils and dry conditions makes it a valuable low-maintenance workhorse. Whether planted en masse or as an accent, it brings softness, height, and rhythm to the late-season garden.

Companion Plants: Pair with the steely blue tufts of Festuca 'Beyond Blue', the bold magenta blooms of Echinacea 'Magnus', and the deep violet spikes of Salvia 'Caradonna' for a sun-loving composition full of contrast, movement, and long-season pollinator support.

Care Instructions: Plant in full sun with excellent drainage. Water during establishment, then infrequently. Cut back hard in early spring to 15–20 cm to maintain a bushy, upright habit. Avoid overly rich soil or excessive fertilization, which can cause floppiness. Requires minimal care once established.

History: Native to the dry steppes of Central Asia, Perovskia atriplicifolia gained popularity in North American gardens in the late 20th century for its hardiness, drought tolerance, and luminous flower display. It remains a favourite for sustainable and ornamental landscapes alike.

Final Thoughts: With its silvery stems and sky-toned flowers, Perovskia atriplicifolia brings a dreamy, drought-defying presence to the garden—softening bold edges and shimmering through the height of summer into autumn’s golden light.
