Uses: Purple fruits of many (not all) Dianella species are edible and have a sweet and slightly nutty flavour (don’t eat too many), others have a horrible burning taste (D. tasmanica) and are not edible. White leaf bases of some Dianella species are edible raw or cooked (D. revoluta). Juice from the fruit used as a dye (dark blue) and traditionally rubbed into sea ulcers. Fibrous leaves used for weaving dillies and baskets and can be split in two and twisted to make a strong string or rope. Rhizomes traditionally eaten after roasting and pounding.
