Coast rosemary

Westringia fruticosa

Description

Coast rosemary naturally occurs in southeast Australia where it is native to sand dunes and coastal bluffs in both sandy and alkaline soils, and where it endures daily wind and salt spray. It is a fine textured evergreen shrub mounding 5-6 ft. tall, capable of spreading 5-8 ft. wide. Small rosemary-like leaves grow to 1/2 in. long, are pale green above, white below and occur in whorls on whitish stems. Small white flowers occur at the tips of branches where they provide modest accent character during spring and intermittently throughout warm periods of the year.

The Coast rosemary is a fast growing species that is valued in Inland Empire landscape and gardens as a foliage plant that is attractive when clipped or unclipped. Plant in sunny locations, in well-drained soils and reduce watering during the summer. It is a reliable shrub with few pests or problems, and tolerant of temperatures to 10-15°F. Cultivars include: W. f. ‘Morning Light’ has yellow-green foliage with white margins and white flowers, grows 3 ft. tall, 4-6 ft. wide, and W. f. ‘Smokey’ grows to 5-6 ft. tall and as wide with pale gray foliage and white flowers.
