Botanic information
Leaf: The glaucous green flat twisted linear leaves have an acute apex and are keeled at the base. When crushed they are aromatic.

Flower: The campanulate flowers have 6-acute oblong perianth segments and 6-stamens. They are arranged in a terminal umbel that is held above the foliage on a slender scape that is up to 600mm tall and is sustained by a spathe. They appear during early summer. 

Fruit: The small loculicidal capsule contains minute black seeds that are very viable but the plant is commonly reproduced vegetatively.
