Rosmarinus ‘Blue Lagoon’ (Rosemary)

How to grow Rosmarinus ‘Blue Lagoon’ in NZ

Plant ‘Blue Lagoon’ in full sun and well-drained soil for the best flowering and foliage quality. It thrives in poor to moderately fertile soils and tolerates coastal conditions. Water regularly during establishment, then only during extended dry periods. Prune lightly after flowering to maintain shape and encourage new growth. Avoid heavy fertilising, as it can reduce flavour intensity and flowering.
