forest flaxlily (Dianella tasmanica)
Also known as Tasman flaxlily or Blueberry flaxlily.
This strap-leaved lily is a robust plant, which self-propagates easily. It tolerates salt, heavy shade and full sun. The delicate purple flowers, with yellow stamens, are produced in clusters from spring to summer. Looks great as a mass planting under large trees.
Aborigines ate the fruit (similar taste to grapes) and the fruit was also used to dye the leaves of Lomandra, which were used to make baskets.
