Summary

Prostanthera scutellarioides, commonly known as Coast Mint Bush, is an evergreen shrub native to the coastal and mountainous regions of New South Wales, Australia. It typically grows to a height of 0.3–2.5 m (1 ft 0 in – 8 ft 2 in) and features ridged branches. The Coast Mint Bush has a bushy habit with small, linear leaves that emit a faint aroma when crushed. Its flowers are a notable feature, ranging from pale to deep mauve, and are arranged in leaf axils, blooming profusely in the spring and summer. The flowers are tubular and spotted, adding ornamental value to the plant.

This shrub is valued for its aromatic foliage and showy flowers, making it an attractive choice for gardeners. It is often used in ornamental gardens, as a border plant, or for creating low hedges. The Coast Mint Bush is relatively easy to maintain and thrives in a variety of soil types, provided they have good drainage. It prefers a position in full sun to part shade. While generally pest-free, it can be susceptible to root rot in poorly drained soils and may be affected by mint bush rust, a fungal disease. Pruning after flowering encourages bushiness and prevents the plant from becoming leggy.CC BY-SA 4.0
