      Apparently from what I’ve read here and in other places, the berries are eatable both raw or cooked. I think I recently got some of this myself so plan to once it gets berries on it to try them.

          The berries in Dianella carulea are edible. You are confusing with other Dianella, like D.tasmanica, wich is poisonous.
          Thank you for your comment Taylor.


    Berries are edible and tasty, in my opinion, for what that’s worth!
    They have a texture very similar to a lillypilly fruit, so kind of spongy and crunchy, if that makes sense.
    I can’t describe the flavour, its not like anything I’ve had before, but its fairly subtle.
    Birds love them so you have to get in quick to get some when they happen!
    They fruit best in years with more rain (like most things I guess)

      I’ve never tried it.
      I tend not to uproot this pants as they are usually in bush regen sites or in protected areas.
      The berries I say are fair go.
      Thank you for your comment Tanya 🙂
