    Planting guide

    Plant in a sunny spot with well-drained soil, spacing plants about 60cm apart. Water well until established, then reduce watering to encourage deep-root growth.

    Care tips

    Perovskia thrives in well-drained soil and full sun. Cut back stems to around 15cm in early spring to encourage fresh, bushy growth. Avoid overly rich soils, as this can cause the plant to become floppy. It requires little feeding—an annual mulch of compost or well-rotted manure is sufficient.

    Winter care

    This hardy plant withstands cold UK winters, but leaving the old stems in place until early spring provides additional frost protection. Apply a light mulch in colder regions to safeguard the roots.
