Perovskia ‘Blue Spire’ – Russian Sage with Silvery Foliage and Lavender-Blue Flowers
Perovskia ‘Blue Spire’, commonly known as Russian Sage, is a striking perennial valued for its airy lavender-blue flower spikes and finely divided silvery foliage. Flowering from midsummer well into autumn, it creates a soft haze of colour that brings movement and texture to sunny planting schemes.
The aromatic silver-grey leaves form an elegant backdrop to the tall flower stems, while the loose, upright habit adds a relaxed naturalistic feel to borders and prairie-style gardens. Its long flowering season and drought tolerance make it particularly valuable for low-maintenance planting.
The delicate flowers are highly attractive to bees, butterflies, and other pollinators, adding both wildlife value and seasonal movement to the garden.
Thriving in full sun, ‘Blue Spire’ performs best in free-draining soil and is especially suited to dry, gravel, and Mediterranean-style gardens. Once established, it is highly drought tolerant and requires very little maintenance.
Its soft silver tones combine beautifully with grasses, echinacea, and warm-coloured perennials, creating naturalistic combinations with long-lasting interest.
Elegant, resilient, and full of movement, Perovskia ‘Blue Spire’ is an outstanding choice for adding colour, texture, and pollinator appeal to the garden.
