Ideal placement of a Perovskia atriplicifolia 'Blue Spire'

This species prospers in a wide range of soil types, provided they are well-drained, which is essential for its health and development. Its drought-resistant nature makes it well-suited for areas that experience dry spells. Despite its hardy disposition, ensuring that the soil has good drainage will help prevent water from accumulating around the roots, thereby fostering a stronger and more resilient plant.

How do I plant a Perovskia atriplicifolia 'Blue Spire'?

The species thrives in well-drained soil and is versatile enough to adapt to various soil types. When planting, consider spacing to accommodate its mature width and allow for proper air circulation, promoting a healthy, bushy form. Water the plant regularly to maintain average soil moisture, particularly during dry spells, as this species has average water needs. With the correct care, this plant will become a stunning, fragrant addition to any border or garden grouping.

Pruning a Perovskia atriplicifolia 'Blue Spire'

Pruning of Perovskia atriplicifolia 'Blue Spire' is best conducted in early to mid-spring, safeguarding the plant from potential damage due to late frosts. As new growth appears and buds begin to swell, trim back the old stems to just above a strong pair of buds, approximately 15-30 cm from the ground.

Once established, the plant's drought-resistant nature becomes evident, requiring less frequent watering sessions. It is advisable to water deeply and less often to promote resilience and self-sufficiency in the plant, particularly in periods of high temperatures or extended dry spells.

Fertilising a Perovskia atriplicifolia 'Blue Spire'

To support the robust growth and enhance the vibrant blue and purple hues of its blooms, Perovskia atriplicifolia 'Blue Spire' benefits from regular fertilization.

Further feeding is generally not necessary, as this species is adapted to thrive with minimal care. Over-fertilization should be avoided to prevent excessive leaf growth at the expense of flowering. With the right fertilization regimen, this plant will exhibit its characteristic aromatic foliage and striking flower spikes from midsummer to early autumn, adding both visual and sensory appeal to the garden.
