about.
Machaerina rubiginosa | common spike rush, baumea
A vigorous, creeping rush best suited to wetland revegetation and damp, low-lying sites. It forms spreading stands of slender, rush-like foliage that ranges from bluish to dark green, creating a dense and effective ground layer. Reddish-brown flowering spikelets are produced above the foliage in summer, adding subtle seasonal colour and texture. Thriving in full sun with ample moisture and room to spread it is highly effective for erosion control and for improving water quality in nutrient-rich or contaminated conditions. Perfect for use in both ecological restoration and landscape planting where a resilient, textural wetland species is required.
