Over a quarter of Australia's butterflies use native grasses as their host-plants and 'Mat-Rushes' (Lomandra species) – which vary greatly in size, and habitats – are the the host-plants for more than 17 species of native Australian butterflies!
The largest Lomandra is the 'Spiny-Headed Mat-Rush' – which is a host-plant for 9 species of ‘Ochre' butterflies
Spiny-Headed Mat-Rush is widely used by Councils – as it's a VERY hardy plant (and widely available). It’s ability to soak-up and store rainfall and ground water in it’s thick leaves – also makes it VERY useful for it’s fire-resistance properties
Spiny-Headed Mat-Rush (aka ‘Basket Grass’) has always been a VERY significant plant to Australia’s first nations: It’s seeds have been harvested to make bread for millennia. The long, smooth-edged and strappy leaves have been used to weave mats for sitting and lying upon (why they're called ‘Mat-Rushes’) as well as baskets, bags and fishing pots etc. The soft white ‘blanched’ leaf base is also nutritious for a snack – or as a bush-survival food.
Spiny-Headed Mat-Rush makes a great addition to gardens, verges, habitat corridors, parklands, regeneration projects...
