Coast Rosemary is a drought-tolerant Australian shrub with fine, needle-like foliage and delicate flowers ranging from white to pink or purple, thriving in Mediterranean-style gardens and coastal landscapes. It is excellent for erosion control, wildlife habitat, and low-maintenance permaculture designs.

Why grow it

Coast Rosemary offers a finer, more delicate foliage texture than many other drought-tolerant Mediterranean shrubs, with a more compact growth habit than rosemary or lavender in comparable climates. It performs well in poor, sandy, or gravelly soils where establishment can be challenging for other ornamentals, making it useful for stabilizing disturbed sites. The extended flowering period and appeal to pollinators add seasonal interest without requiring supplemental feeding or regular pruning once established.

Watch out for

Establish young plants with consistent moisture during the first growing season, as drought tolerance develops with maturity. In humid tropical or subtropical regions, fungal issues may develop if air circulation is poor or soils remain waterlogged. Older plants can become leggy or sparse in the center if not periodically rejuvenated with light pruning, though heavy cutting back may not regenerate from old wood as readily as some related species.
