Coast Rosemary

This tough plant stands strong in drought, heat, and salt spray. Although some of the wild forms of this plant have a wayward, unkept look, cultivated forms of coast rosemary are more compact, set brilliant spring flowers, and do well with shearing. Simply prune the evergreens into a pleasing shape and enjoy their easy-care ways throughout the garden.

Planting Partners for Coast Rosemary

Colorful and long-lived planting companions include heavenly bamboo Nandina spp., stonecrop Sedum spp., aloe, and yucca. Perennial salvia and eucalyptus also make good companions. Coast rosemary is an excellent plant for stabilizing a slope and adds evergreen color to rock gardens. There are multiple landscape uses for this almost-no-maintenance plant. 

Coast Rosemary Care

Easy-to-grow in average, sandy, or well-drained soil, coast rosemary thrives in bright sun, though it will tolerate part shade. Once established, it is highly drought tolerant. Plant coast rosemary in early spring and water it regularly during the first growing season to encourage a strong root system. Discontinue watering after the first growing season and count on the plant to handle extreme drought. A layer of coarse mulch over the root zone helps conserve soil moisture.

Coast rosemary can be fertilized in spring to promote fast growth, although fertilization is not necessary. Avoid fertilizer combinations that have a high phosphorus formula.

Coast rosemary requires little pruning, especially the groundcover types. Prune upright varieties as needed to shape the plants after spring flowering.

New Types of Coast Rosemary

Plant breeders have introduced several new varieties of coast rosemary to the market, including small, ground-hugging varieties and kinds that sport striking blue-purple flowers. They are all rugged, easy-to-grow, and tolerate dry soil and high temperatures.
