How to grow

Cultivation Prefers a well-drained neutral to alkaline soil but tolerates acidic conditions. In heavy soil improve drainage as lavender does not tolerate waterlogging. Potash will encourage flowering but high nitrogen fertilisers and manure will result in 'floppy' plants

Propagation Propagate by semi-hardwood cuttings, may not come true from seed

Suggested planting locations and garden types Banks and Slopes Flower borders and beds Garden Edging City & Courtyard Gardens Cottage & Informal Garden Gravel Garden Mediterranean Climate Plants Patio & Container Plants Rock Garden Wildlife Gardens
