Dianella caerulea is a herbaceous perennial from the Asphodelaceae family of plants. They also call it the Blue Flax-lily, Blueberry Lily, or Paroo Lily. It is native to eastern Australia and Tasmania.

In 1802, John Sims first described this plant in Curtis’s Botanical Magazine. The genus name is after Diana, the Roman goddess. And caerulea is Latin for “blue”.
Dianella caerulea grows from underground rhizomes and spreads. The sword-shaped, green leaves can grow 70cm or 28in tall. The blue flowers appear in spring and summer. The flowers are blue with yellow-brown anthers. After the flowering is done bright blue-violet berries adorn the plant. The berries are edible.
