How to grow

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

Propagation Propagate by seed sown in a cold frame in spring, or by semi-hardwood cuttings in summer

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 Wildlife Gardens
