About this plant
Prostanthera cuneata, commonly known as alpine mint bush, is a compact evergreen shrub celebrated for its aromatic foliage and profuse floral display. In late spring to summer, it produces masses of small, tubular white flowers, often tinged with pale lilac and marked with purple and yellow in the throat. These delicate blooms contrast beautifully with the dense, dark green leaves, which release a refreshing minty fragrance when brushed or crushed.
Native to the alpine regions of southeastern Australia, Prostanthera cuneata thrives in cooler climates and rocky habitats. Its origin in these rugged environments speaks to its hardiness and adaptability, making it a valued choice for ornamental gardens. This shrub is particularly appreciated for its combination of aesthetic appeal and sensory interest, offering both visual beauty and aromatic foliage.

Design tip
Alpine mint bush is especially nice near a path or patio, where brushing against the leaves releases their fresh minty fragrance. In late spring, masses of white flowers touched with pale lilac brighten the dark green foliage and give the shrub a soft, flower-filled appearance.
