How to care for Perovskia Blue Spire:
Perovskia thrives in full sun and well-drained soil, making it ideal for Mediterranean-style or gravel gardens. This Russian Sage is drought-tolerant once established but overwatering or rich soil leads to weak growth and fewer flowers.
Avoid pruning back in autumn as winter seed heads provide interest and food for birds. In March, prune hard to 15-30cm (6-12in) from the ground to promote bushier growth and prevent flopping, then apply a 5-7cm (2-3in) layer of well-rotted compost or manure around the base, avoiding the stems.
