Planting & care

Help it thrive

Planting guide

Plant in spring or autumn in fertile, well-drained soil. Choose a sunny or lightly shaded position. Space plants to allow air movement and reduce the risk of mildew. Deadhead regularly to encourage more blooms and extend the flowering period.

Care tips

Deadhead spent flowers to prolong blooming. Water during dry spells, especially in the first season. Divide clumps every few years in spring to maintain vigour. Avoid overly wet conditions in winter.

Winter care

Cut back faded foliage in late autumn or leave until early spring for added protection. Apply a light mulch around the crown to guard against cold and wet conditions. Ensure good drainage over winter to prevent rot.
