This sterile hybrid is a showy and popular ornamental perennial grass. It grows rapidly in dense clumps of burgundy coloured foliage up to 1.5 m high with arching purple-pink flower plumes in summer.

This is a small tufted perennial rush with long strap-like green leaves to 1 m. A tall, slender, yellow flower spike appears from the leaf base in the early growing season and persists for many weeks. As the spike matures, the structure is replaced by a tan, fruit-bearing shaft, composed of attractive clusters of small nutlets. This species is extremely hardy and tolerant of climatic extremes and most soil conditions. Widely grown for soil stabilisation. There are various smaller and more compact forms available such as Lomandra longifolia 'Tanika' and Lomandra confertifolia Little Con'.
