Westringia fruticosa ‘Smokey’, commonly known as Coastal Rosemary, is a refined, drought tolerant shrub that brings a soft, silvery tone and clean structure into the landscape. It’s especially useful for creating a cohesive, low maintenance planting with a more muted palette.

The foliage is narrow and slightly fuzzy, with a smoky gray green color that gives the plant its name. It forms a dense, naturally rounded shape that can be left informal or lightly shaped for a more polished look.

Small, pale lavender to white flowers appear throughout the year, often in cycles. They’re subtle but add a gentle layer of interest without overpowering the foliage.

It works well as a low hedge, foundation plant, or as a repeating element in a design. Its versatility and durability make it a reliable choice for both structured and relaxed landscapes.

Westringia ‘Smokey’ grows best in full sun and requires well drained soil. Once established, it is highly drought tolerant and performs well in coastal and inland conditions.

It typically reaches about 4 to 6 feet tall and wide, forming a full, rounded shrub. It is well suited for USDA zones 9 through 11. The foliage is evergreen.

This plant has low toxicity and is generally safe for gardens with pets and children.

The flowers may attract pollinators such as bees.

It is generally deer resistant.

Westringia fruticosa ‘Smokey’ fits especially well into Mediterranean, coastal, and Australian-inspired garden designs, where its color and form can be used to create structure and continuity.

It pairs well with plants like Grevillea species to reinforce that Australian palette and add unique texture, Anigozanthos ‘Bush Gold’ to introduce bold vertical color, Hesperaloe parviflora for structure and seasonal bloom, and Geijera parviflora to add a soft, airy canopy layer above.

Expert Tip:

Place this where you want a clean, consistent form with minimal upkeep, because it naturally holds its shape well. Occasional light pruning will keep it dense and refined without forcing it into a rigid structure.
