Dianella caerulea is a small native lily that is being used more and more in public landscaping, despite the fact that’s a bit boring most of the year, as it then blossoms and fruits with the most gorgeous sprays of purple flowers
and edible indigo berries. I have a weakness for purple, so they’re pretty high on my list.
Don’t eat from wild plants of unknown origin – https://www.childrens.health.qld.gov.au/poisonous-plant-blue-flax-lily-dianella/ warns that some children have reported breathlessness and dizziness.
However https://www.daleysfruit.com.au/buy/dianella-caerulea-blue-flax-lily-tree.htm lists them under bush foods, as do most sites.
The berries are sweet, and if you eat the seeds, the total flavour becomes nutty.
They can be eaten raw or cooked, and are stunning as a decoration, but don’t eat too many.
Grows in clumps up to about 1 metre high with a spreading rhizome under the grounds, with rich green strappy leaves up to 75cm.
The flowers bloom in spring and summer, followed by the small berries.
Prefers full sun to part shade, it’s perfect for borders and rockeries and understory rainforests.
Likes well-drained soil and can tolerate dry periods.
http://www.cpbr.gov.au/apu/plants/dianella.html lists the traditional uses
including tea, pounding the roots and cooking, and using the strong fibre
in basket weaving.
