Stronger, longer perennial colour
Perovskia Blue Steel is one of our top-performing perennials, and also known as ‘Russian sage’. Growers can now produce high-quality, affordable Perovskia atriplicifolia from professional seed. Blue Steel offers higher and much more uniform germination than other seed varieties. Growing beside leading vegetative varieties, you can’t see the difference, and it is much faster to grow!

This Perovskia combines the best summer-blooming lavender-blue colour with outstanding late-season garden performance. The aromatic silvery foliage carries clouds of small blue flowers on strong silver stems that do not break or split easily. Blue Steel is a compact Perovskia (50-60 cm first year, 80-90 second year) with sturdy controlled habit. Hardy in zone 4a and higher, Russian Sage is both heat and drought tolerant – perfect for landscaping and accent plants!
