Detailed Description:
  • Appearance:

    Westringia fruticosa is a dense, bushy shrub with a rounded habit. Its leaves are narrow, often with a silvery underside, giving the plant a greyish appearance. The small, white or pale mauve flowers appear in clusters along the stems, particularly during spring and summer. 

  • Size:

    It typically grows to a height of 1-1.5 meters (3-5 feet) and a similar width, though some varieties can be more compact. 

  • Hardiness:

    This shrub is exceptionally hardy, tolerating drought, coastal conditions (including salt spray), and a range of soil types. It can also handle some frost. 

  • Light and Soil:

    Westringia fruticosa prefers full sun but can tolerate partial shade. It thrives in well-drained soil and is relatively low-maintenance. 

  • Uses:
    • Hedging and Screening: Its dense growth habit makes it ideal for creating low hedges or screens. 
    • Specimen Plant: It can be used as a standalone shrub to add structure and interest to a garden. 
    • Coastal Gardens: Its tolerance to salt spray and drought makes it a perfect choice for coastal landscapes. 
    • Groundcover: Some varieties, like ‘Mundi’, are low-growing and spreading, making them suitable for groundcover. 
    • Cut Flowers: The upright growth habit and long-lasting flowers make it suitable for cut flower arrangements. 
  • Maintenance:

    Westringia fruticosa generally requires minimal pruning to maintain its shape and density, according to the Australian Plants Society. Regular pruning can encourage a more compact, formal hedge shape. 

Varieties:
  • ‘Wynyabbie Gem’: Known for its fast growth and abundant pale lavender-mauve flowers.
