How to Grow

Suggested planting locations and garden types

  • Coastal
  • Cottage and informal garden
  • Gravel garden

Pruning

Pruning group 10; deadhead after flowering. Trimming in late summer prevents plants from becoming straggly, but you can leave plants for a season to benefit wildlife with seeds or as shelter if you prefer. Avoid pruning in autumn in wet or cold regions as this may leave plants vulnerable to winter damage. Avoid cutting back into old wood

Pests

May be susceptible to rosemary beetle and cuckoo spit (froghoppers)

Diseases

May be susceptible to grey moulds (Botrytis) and honey fungus (rarely)
