Form: grass — perennial
Status: not present in WA
Thatching reed is native to South Africa. A very resilient plant that will tolerate drought (once established), frost and coastal seaside conditions. Although it prefers acidic soil it will grow in almost any soil as long as it drains well.
Thatching reed is a tall, grass or reed-like tussock with a diameter of 0.5-1 metre at the base and a spread.
Stems: Dark-green stiff upright stems forming a fan shape.
Flowers: Stems are topped with brown to golden brush-like flowers in summer.
Seeds: The seed comes in the form of a tiny nutlet inside the old flower, which forms two small wings when mature and allowing wind dispersion. The seeds are produced in very large quantities by each female plant, but are not all viable; a large number of nutlets are empty inside.
