Description.
A tuft-forming herbaceous species with strap-like leaves up to 80 centimetres in length. More solitary than D. revoluta. Leaves are softer than those of D. revoluta and may have a pale blue or silver bloom. Flowers are carried in loose clusters on tall flower spikes which exceed the foliage in height. Flowers are pale blue with orange filaments and yellow anthers. Flowers are followed by green fruits which turn a vivid blue at maturity. These each contain several glossy blue-black seeds.
Propagation.
Propagation by seed gives variable results and seed may take months to germinate. Soaking in soapy water or smoke water may enhance germination, as may lightly scratching the seed coat. Propagation can also be carried out by dividing the underground rhizomes.
Flowering.
Chiefly September and October. Often slightly later than D. revoluta.
Locations.
Ubiquitous in reserves and by roadsides, though less abundant that D. revoluta.
Extra Notes.
There is some uncertainty about the identity of local populations of this species. The pale bloom described here is characteristic of Dianella porracea, but that species is not reported east of Griffith.
