Description: Isolepis nodosa, commonly known as Knobby Club-rush, is a perennial, grass-like sedge native to coastal regions of Australia and New Zealand. It features dense clumps of slender, dark green stems that can reach up to 1 meter in height. The plant produces distinctive, rounded, brown flower heads near the tips of its stems, typically blooming from spring through summer. Knobby Club-rush thrives in a variety of conditions, including sandy soils and coastal environments, making it ideal for stabilizing dunes and revegetation projects. It is tolerant of salt spray and periods of drought once established. This hardy plant is well-suited to Melbourne's climate and can be used effectively in coastal gardens, wetlands, and as an ornamental feature in landscaping.
