Buy Westringia Plants Online Australia — Hardy Coastal Rosemary Shrubs for Hedging, Borders & Gardens

About

If there is one native shrub that earns the title of Australia's most reliable all-rounder for garden structure, it is Westringia. Commonly known as Coastal Rosemary or Native Rosemary — names that refer to the shape of its narrow, grey-green leaves rather than any similarity of flavour or fragrance — Westringia is a member of the mint family, Lamiaceae, and is native to coastal cliff faces, headlands, and sandy soils around Australia's eastern and south-eastern coast. It has evolved in some of the most exposed, wind-battered, salt-laden garden conditions imaginable, which is precisely why it performs so consistently well in Australian suburban and coastal gardens where other plants struggle. Westringia handles drought, frost, salt spray, coastal winds, reflected heat, poor sandy soils, and moderate clay with an equanimity that few other ornamental shrubs match. It flowers almost year-round in warm coastal climates — small tubular blooms in white, pale lavender, blue-purple, or mauve depending on variety — and the foliage provides excellent year-round structure in grey-green, silver, or variegated forms. It responds exceptionally well to pruning, which makes it the go-to native alternative to Lilly Pilly and Buxus for formal hedges, box plantings, topiary, and low borders. Unlike many Proteaceae natives (Banksias, Grevilleas, Adenanthos), Westringia does not have a phosphorus sensitivity — it tolerates average phosphorus levels in standard fertilisers and soils, which makes its care significantly simpler than some other Australian natives. A balanced fertiliser in spring, regular tip pruning to maintain density, and good drainage are essentially all it requires. Our collection of 19 Westringia varieties is the most comprehensive available online in Australia, spanning the full range from the groundcover-habit Fruticosa Prostrate (30–50cm) through compact box-hedge varieties (Grey Box, Aussie Box, Blue Gem) to taller screen and hedging forms (Naringa, Longifolia).
