Botanic information
Leaf: The arching dark green long linear leaves have an acuminate apex. The cultivar 'Evergold' has a broad creamy central stripe. 

Flower: The tiny flowers are arranged in a brown spike up to 30mm (1¼in) long and appear amongst the foliage during spring. The female and male flowers are arranged above each other and the female flower is enclosed in a bladder-like perigynium and has 1-style and 2 or 3 stigmas. 

Fruit: The tiny 3-angled fruit is a flattened convex-shape nut and is surrounded by a persistent perigynium. The small seeds are viable but the plant is commonly reproduced vegetatively.
