When its flowers appear in August and September, this RHS AGM plant, Perovskia 'Blue Spire', could be mistaken for a variety of Lavender. Its blooms are an attractive blue-purple colour and give off a sweet scent. They also attract droves of bees and butterflies, making the hardy shrub suitable for wildlife gardens. However, unlike Lavender, Perovskia 'Blue Spire' produces tall stems, each of which bears many flowerheads. It is therefore suitable to grow at the back of sunny borders, even in exposed, costal areas. Height: 1.2m (3'11). Spread: 1m (3'3).
Lavender-like purple-blue flowers are borne on silvery stems from late summer, above narrow, aromatic, silvery-green foliage. Russian Sage is a robust shrub which can thrive in poor and chalky soils in exposed areas, looking especially great planted en masse. Perovskia ?Lacey Blue? is British bred and has a neat habit, making it ideal for containers and borders. The foliage is aromatic and makes a good choice for planting down driveways. Height: 50cm (20?). Spread: 60cm (24?).
If you are on the hunt for a blue flowering shrub then Perovskia atriplicifolia 'Silvery Blue' could be just what you have been looking for. Its a versatile plant, with great drought and open exposure tolerance, making it a good choice for coastal gardens. This Russian Sage has aromatic, silvery foliage and stems that are covered in lavender blue flowers in summer. Perfect for garden borders with a blue, purple, white palette, or planted in groups or in lines, to create large areas of purple colour. A very low maintenance plant for the garden. Height and spread: 60cm (24).
Commonly know as Russian Sage, Perovskia 'Blue Spire' is an upright deciduous shrub with deeply cut grey-green aromatic foliage and striking flower spikes. Named after its sage-like fragrance, the scent is wonderfully fresh, and released when the foliage is brushed past or crushed, so this is a great plant for lining a path. From July until autumn tall silvery spires appear, covered in masses of tiny violet-blue tubular flowers. Recommended by the RHS as a 'Plant for Pollinators', they are a favourite with butterflies and bees and other beneficial insects. Perovskia loves to grow in full sun and prefers quite poor, well drained soil that's moderately fertile, so it's well suited to growing in dry gravel gardens and coastal locations, where it will cope well with salty air and drying breezes. Fully deserving its coveted RHS Award of Garden Merit, you can be sure that this is a proven garden performer, guaranteed to be suitable for UK gardeners at every level of experience. You can therefore plant this in the garden with confidence, for stunning displays for many years to come. Supplied as 3 x established plants in 9cm pots, ready to plant out, reaching a height of 1.2m (4ft) and spread of 1m (3ft).
