About Your New Westringia fruticosa 'Zena' – Compact Coastal Rosemary
Westringia fruticosa 'Zena' is a compact, naturally rounded coastal rosemary cultivar bred for tighter, neater growth than the species form. It carries fine linear grey-green foliage and produces soft white tubular flowers through spring with lighter sporadic flushes through summer and autumn. Its dense habit develops naturally, without the need for hard clipping, making it one of the easiest Australian natives for low hedging and mass planting.
It performs in full sun to part shade and tolerates coastal exposure, salt-laden winds, and sandy or well-drained soils. Once established, 'Zena' is highly drought tolerant and frost hardy across most of southern Australia. A light tip-prune after the main flowering flush is enough to keep it tidy, with no formative shaping required.
For low formal hedges, clipped balls, mass-planted borders or tidy structural infill in coastal and native gardens, Westringia 'Zena' is a dependable choice. It suits modern planting schemes, low-maintenance landscapes, embankments, and council or civic projects where reliable, hardy, evenly-shaped shrubs are specified.
