Westringia fruticosa, a hardy Australian shrub with attractive blue-green leaves that have a subtle fragrance and can be used for culinary purposes

Westringia fruticosa, commonly known as the coastal rosemary or emu bush, is a hardy, evergreen shrub native to Australia. It's a popular choice for gardens due to its attractive foliage and relatively low maintenance requirements.

Leaves are a key feature of this plant. They are typically arranged in whorls of three or four around the stems and are narrow, lance-shaped, and possess a distinctive blue-green hue. The leaves are covered in tiny hairs, which help to reduce water loss and protect the plant from harsh environmental conditions. This hairy texture also contributes to the plant's silvery appearance.

While the name "coastal rosemary" suggests a similarity to the culinary herb, the leaves of Westringia fruticosa do not have the same strong aroma. However, they do emit a subtle, pleasant fragrance, particularly when crushed. This fragrance is often described as being similar to that of lavender or mint.

The leaves of Westringia fruticosa are not only attractive but also play a vital role in the plant's survival. They help to regulate water loss, protect against pests and diseases, and contribute to the plant's overall health and vigor.

In addition to their aesthetic appeal, the leaves of Westringia fruticosa can also be used for culinary purposes. They can be added to teas, sauces, and marinades to impart a subtle flavor and aroma.
