Lomandra rigida, commonly known as Stiff Mat Rush, is an evergreen perennial grass-like plant native to open woodlands and dry sclerophyll forests in Southwestern Australia. It typically grows to a height of 0.1 to 0.3 meters and features narrow, stiff, and sharply pointed leaves that can produce a spiky appearance. The species is dioecious, with separate male and female plants. Cream or yellow inflorescences appear from October to December, and while the flowers are not particularly showy, they add a subtle charm to the plant’s overall texture.

Stiff Mat Rush is valued for its drought tolerance and low maintenance requirements, making it a suitable choice for rockeries, borders, and mass plantings in gardens. It is also used for erosion control due to its dense root system. In cultivation, it thrives in full sun to part shade and is adaptable to a range of soil types, provided they have good drainage. This plant is generally free from serious pests and diseases, but it can suffer from root rot in poorly drained soils.CC BY-SA 4.0
