Lavender is completely at home in Perth's Mediterranean climate. Full sun. Very well-drained soil - waterlogging is the most common cause of death. Sandy Perth soils are ideal. Minimal watering once established. Prune by up to one-third immediately after flowering. Do not cut into bare woody stems. Silver Princess has particularly fine silver-grey foliage alongside its white-to-pale lavender flowers - the foliage is outstanding year-round even when not in bloom.
