Summary

Ajuga australis, commonly known as Austral Bugle, is an evergreen perennial herb native to a variety of habitats in Southeastern Australia, including open woodlands, grasslands, and forest margins. It typically forms a low-growing mat reaching up to 10 inches (25 cm) in height, with a spread of 12-18 inches (30-45 cm). The plant features a rosette of dark green, glossy leaves and erect stems bearing whorls of tubular, two-lipped purple flowers that are highly attractive to pollinators. Flowering occurs mainly in spring, though sporadic blooms can appear throughout the year. Austral Bugle is relatively short-lived, with individual plants lasting two to three years.

Austral Bugle is valued for its ground-covering ability, ornamental flowers, and low maintenance requirements. It is often used in garden borders, rockeries, and as underplanting for larger shrubs. This plant thrives in part shade to full sun and adapts to a range of soil types, provided they have good drainage. Ajuga australis can be propagated easily from cuttings, making it a convenient choice for gardeners looking to expand their plantings. However, gardeners should be aware that in some conditions, it can spread aggressively outside its native range.CC BY-SA 4.0
