How to grow Dusty Miller

Written by the GardenDecoded editorial team · Last reviewed 21 July 2026 · Written for UK gardens · How we research our guidance

Planting

Plant in spring in a hot, dry spot — gravel gardens and the front of a sunny border suit it. The silver-grey woolly foliage is the point for much of the year, so give it a position where the rosettes are visible. It hates rich damp soil and rots in it.

Pruning

Deadhead to prolong flowering, but leave a few heads if you want it to seed around. Cut old flowered stems back to the basal rosette in autumn.

Propagation

Easiest from seed, sown in spring or summer; it self-seeds reliably and usually keeps itself going in the garden without intervention. Seedlings transplant well when small.

Pests and diseases

Generally trouble-free. Losses are usually from winter wet rather than pest or disease.

Value to wildlife

The flat magenta flowers are visited by bees and butterflies, though the nectar is held in a narrow tube that suits longer-tongued insects.

Notes

Short-lived, often behaving as a biennial or brief perennial, so let some seed drop to maintain a colony. Formerly listed as Lychnis coronaria and still often sold under that name.
