Poa sieberiana

Common Name:
Grey Tussock Grass

Description:
Poa sieberiana, commonly known as Grey Tussock Grass, is a fine-leaved, clumping native grass known for its silvery-blue to grey-green foliage and soft, feathery seed heads. Naturally found across a wide range of Australian regions, including alpine and woodland areas, it brings texture and movement to the landscape while being incredibly resilient. Flowering from spring into summer, it produces upright stems bearing loose, airy seed heads in shades of pale cream to golden-brown that catch the light and provide seasonal softness. Well suited to Melbourne’s climate, Poa sieberiana thrives in full sun to part shade and is tolerant of drought, frost, and poor soils — including clay and sandy substrates. Its dense form makes it effective for mass planting, native revegetation projects, and erosion control. This species is particularly valued in naturalistic or bush-style gardens and works beautifully alongside other tough native grasses and ground covers.
