Why It’s a Great Idea to Plant in Winter
Description:
Westringia ‘Low Horizon’ PBR is a hardy, ground-hugging native shrub, specially bred for its ultra-low, dense, and spreading habit. Featuring soft grey-green foliage and occasional pale mauve flowers, this variety is perfect for groundcover, mass planting, or as a living mulch. Its tidy, compact form makes it ideal for modern landscapes, native gardens, and coastal sites.
Flowers:
Pale mauve flowers appear mainly in spring and summer, with spot flowering possible throughout the year. The soft blooms complement the fine foliage and attract small pollinators.
