How to Grow

Cultivation

Prefers a well-drained, moderately fertile, neutral to alkaline soil; tolerates acidic conditions, but not heavy, wet soil. See lavender cultivation for further advice

Propagation

Propagate by semi-hardwood cuttings. See our video How to take lavender cuttings for more advice

Suggested planting locations and garden types

City and courtyard gardens
Coastal
Cottage and informal garden
Banks and slopes
Flower borders and beds
Garden edging

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)
