About Grey Box Coastal Rosemary
Westringia fruticosa 'Grey Box' is a shrub in the Lamiaceae family, native to Australia. It reaches around 1 m tall and 1 m wide at maturity, with evergreen and silver-grey foliage. White flowers appear for much of the year.
Where to grow Grey Box Coastal Rosemary
Grey Box Coastal Rosemary suits warm-temperate, Mediterranean and subtropical climates and grows best in full sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds, is a genuinely water-wise choice and is usually left alone by rabbits.
Soil & planting
Grey Box Coastal Rosemary does best in free-draining and sandy soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in. For a screen, space plants about 60 cm apart.
Watering & feeding
Grey Box Coastal Rosemary handles dry conditions well once established. As an Australian native, feed it only with a low-phosphorus native fertiliser. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Prune Grey Box Coastal Rosemary after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. For most gardens, it is low maintenance.
Using Grey Box Coastal Rosemary in the garden
Grey Box Coastal Rosemary earns its place for a fast screen or informal hedge, a feature or specimen planting and pots and courtyard containers. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
Grey Box Coastal Rosemary sits most comfortably beside plants adapted to dry conditions once established and warm-temperate climate. A small cluster gives stronger visual impact than isolated plants scattered through the garden. It combines naturally with other Australian natives in a habitat or water-wise garden.
