      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)

    Cheers

      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 🙂

    I’ve eaten the berries which are a bit underwhelming, but make up for it with that fantastic colour which looks great in a fruit salad. Does anyone know if the flowers are edible?

      Hello Peggy, thank you for your comment. Like all wild things, some bushes taste better than other and yes Dianella carulea flowers are edible too but do not confuse with others in the genus.
      Cheers

    How does one tell the difference between the poisonous and the edible one? They look the same in the photos. (I always lose my plant tags)

      The only Dianella I can vouch for is Dianella Carulea, commonly found and planted in Sydney. As far as I can research only Dianella tasmanica and D. intermedia are toxic although evidence is limited to a few circumstantial cases and no clear exposure and effect has been seen.
      Dianella tasmanica native range is Tasmania, the leaves are substantially bigger than D. carulea, with bigger berries and shap spikes at the back of the leaves (common of all Dianella but noticeably sharp in D. Tasmanica).
      Do not eat anything unless you are 100% confident of identification.
