Perovskia 'Blue Spire'

How to grow Perovskia 'Blue Spire' in NZ

Perovskia 'Blue Spire' grows best in full sun with well drained soil and good airflow. Choose a warm open position to encourage strong flowering, healthy growth, and vibrant foliage colour. This hardy perennial tolerates poor and dry soils once established but dislikes wet ground during winter. Water regularly during establishment, then only occasionally once plants are established. Adding compost and grit to the soil at planting time helps improve drainage and encourages strong root development.

Perovskia 'Blue Spire' care tips

Perovskia 'Blue Spire' is low maintenance and benefits from annual pruning during late winter or early spring. Cut plants back to around 20 cm above ground level to encourage fresh new growth and strong flowering stems for the coming season. Feed lightly with a balanced garden fertiliser during spring to support healthy development. Water during prolonged dry periods while plants establish. Avoid overwatering mature plants as they prefer drier growing conditions once established.

Perovskia 'Blue Spire' size, spacing, and growth rate

Perovskia 'Blue Spire' typically grows to around 1 to 1.5 metres tall and spreads up to 1 metre wide with a naturally upright airy habit. It has a moderate to fast growth rate and quickly forms a striking flowering clump in suitable conditions. For borders or mass planting, space plants approximately 70 cm to 1 metre apart to allow healthy airflow and full development. Regular pruning helps maintain tidy growth and abundant flowering.
