Westringia fruticosa ‘Smokey’ 15g

Westringia fruticosa ‘Smokey’ (Smokey Coast Rosemary, Variegated Australian Rosemary) is a variegated cultivar of Westringia fruticosa, an evergreen shrub native to coastal regions of eastern Australia. It is valued for its compact growth habit, cream-edged gray-green foliage, and reliable performance in drought-tolerant and coastal landscapes. Like other forms of Westringia fruticosa, ‘Smokey’ provides year-round structure while adding foliage contrast to Southern California landscapes.

Origin: Cultivar selection of Westringia fruticosa; specific cultivar origin is not well documented

Landscape Uses: Low hedges, borders, mass plantings, foundation plantings, slopes, commercial landscapes, streetscapes, residential plantings, coastal gardens, and water-wise landscapes

Habit & Size: Westringia fruticosa ‘Smokey’ forms a dense, rounded evergreen shrub with narrow gray-green leaves edged in cream-colored variegation. The foliage provides year-round color contrast and a cooler, grayer appearance than the standard green-leaved species form. Plants typically reach approximately 3–4 feet tall and wide, although mature size can vary depending on irrigation, soil conditions, and pruning. Small white to pale lavender flowers appear primarily during spring and summer, with occasional additional flowering under favorable conditions.

Cultural Requirements: ‘Smokey’ performs best in full sun, where the variegated foliage develops its strongest contrast and plants maintain a compact habit. It tolerates light shade, although growth may become somewhat less dense. This cultivar is well suited to Southern California’s Mediterranean climate, including coastal areas, inland valleys, and urban landscapes. Once established, it requires relatively low irrigation and tolerates periods of drought. Occasional deep watering during extended dry periods can help maintain foliage quality. It adapts to a range of soil types, including clay soils, provided drainage is adequate. Avoid consistently wet soils, which may lead to root problems and decline.

Landscape Uses: Westringia fruticosa ‘Smokey’ is useful as a compact evergreen shrub for low hedges, borders, mass plantings, foundation plantings, slopes, and water-wise landscapes. Its cream-edged gray-green foliage provides contrast when planted with darker green shrubs, native perennials, grasses, and other Mediterranean-climate plants. Its smaller mature size makes it appropriate for commercial landscapes, streetscapes, and residential plantings where a durable, low-maintenance shrub with year-round foliage interest is desired.

Identification Note: ‘Smokey’ is distinguished from the species form by its cream-edged variegated foliage and compact growth habit. It is one of several ornamental Westringia fruticosa cultivars selected primarily for foliage characteristics rather than flower differences. It is often confused with Westringia fruticosa ‘Morning Light’ in the wholesale nursery industry. ‘Smokey’ generally has a cooler, grayer overall appearance, while ‘Morning Light’ shows more cream to yellowish tones. Like other plants commonly called Coast Rosemary, it is not related to culinary rosemary (Salvia rosmarinus / Rosmarinus officinalis).

Pests and Cultural Considerations: This cultivar is generally low maintenance when grown in appropriate conditions. The primary cultural concerns are excessive irrigation, poor drainage, and overgrown woody stems caused by infrequent maintenance. Light pruning can be used to maintain density and shape, but heavy pruning into older wood may reduce recovery. Plants grown with excessive water may become more vigorous and require additional maintenance. Branches or small sections of foliage may occasionally revert to the green foliage color typical of the species and can be pruned out if desired.
