Perovskia atriplicifolia Blue Spire
These spectacular plants, also known as Russian Sage are incredibly popular right now, and it’s easy to see why.
Producing impressive tall spires of silvery leaves topped with spikes of gorgeous, tiny, violet purple bell-shaped flowers bloom in late summer. Loved by butterflies and bees, it makes a great cut flower with its lovely scent, which is a mixture of sage and lavender. Perovskia atriplicifolia Blue Spire holds an RHS Award of Garden Merit.
Native to central Asia, Russian Sage's natural habitat is on dry plains and they are natural sun lovers. They are deciduous shrubs which, once established, are hassle free, drought tolerant (in fact they prefer it) and need an annual pruning in spring.
Perovskia will grow well in any soils, even poor or chalky, as long as they get really good drainage, water-logging will lead to root rot. They like to be in full sun and can withstand seaside air.
Prune hard annually in early to mid-spring for a healthy plant and better flowers that year. If you don’t they will come back week and floppy and generally be an untidy mess.
Cut back previous years flowering stems to within one or two buds of the older woody framework. Remove thin, weak and damaged growth. Then mulch and feed. For the first year keep them moist but not soggy to get them established. In following years they will withstand significant neglect!
They are best planted out in autumn when dormant – if you buy one that is in leaf in the spring be sure it hasn’t been growing in a poly tunnel as it may struggle when you expose it to the elements in your garden.
Russian sage is mainly used as an ornamental plant and is pretty versatile for pairing with lots of late summer ornamental grasses and perennials. You can create a really powerful display planting near other silver leafed perennials, near a lavender bush for example, and as both are bee magnets they are a great choice for wildlife friendly gardens. Tall bright coloured perennials will also look great with it in a mixed border, for examples look at Geums, Sunflowers, Rudbeckia and Helenium to name a few!
