Perovskia Blue Spire


Russian Sage

Upright white stems and masses of tiny deep blue flowers

Russian Sage has thin, aromatic leaves and spikes of vibrant violet or blue flowers that come during August and September.


Choose a spot in full sunlight. It doesn't perform as well in partial or full shade. The soil is less of an issue providing it's well-drained.


Plant in the garden ideally next to a path to get the best from its blue flowers and scented foliage.

Cut back in late Winter or early Spring, removing the spiky growths that carried the previous year's flowers.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
