To grow Perovskia Blue Spire, plant it in well-drained soil in a sunny location. This drought-tolerant shrub thrives in full sunlight, where it can develop its silver-grey foliage and striking blue flowers. Water regularly during dry spells, but avoid overwatering. Prune back after flowering to maintain shape.
Prune Perovskia Blue Spire in early spring before new growth starts. Cut back the previous year's growth to about 10–15 cm (4–6 inches) above the ground. This encourages fresh growth and improves the plant's overall shape. Avoid pruning after flowering to preserve the blooms.
Perovskia Blue Spire generally doesn’t need support, as it grows with a naturally upright form. However, in windy areas or if the plant becomes top-heavy, it may benefit from staking. Use a gentle stake or cage to prevent the plant from falling over during strong winds.
