All of these Westringias are bread in Australia from originally native plants and are tough, drought resistant and tolerant of cold conditions. They will grow in light shade to full sun, coastal positions and in virtually any reasonably well drained soil. Requiring virtually no care requirements, they have the added bonus of flowering against their appealing foliage. A little trimming to shape is recommended, although even left alone they remain compact and true to shape. Feed with a good quality slow release fertiliser in spring. These plants are a great alternative to Buxus and many other choices, establishing quickly and suffering virtually no disease or problems often associated with difficult locations.
