Dianella amoena

About

Dianella amoena, commonly known as the matted flax-lily, is an endangered, herbaceous, perennial plant endemic to Australia. It belongs to the family Asphodelaceae, subfamily Hemerocallidoideae. It has long grey-green leaves which grow in clumps from an underground rhizome, and displays blue-purple flowers in spring-summer, up to 90 cm in height. The common name Matted Flax-lily refers to its extensively rhizomatous nature, sometimes forming large mats up to 5m wide.
