    Some years ago I asked a naturalist friend about the global distribition of Bracken. Commenting on it’s near ubiquity he said he “didn’t understand
    why Bracken hadn’t taken over the world” and related finding it on a caldera floor in the Galapagos where it almost never rains and the temps are in the 100s F.
    On edibility, we here at Wisdom of the Herbs School have come down strongly on the “only as a (very) occasional treat” side, and only steamed, not raw. I cannot cite a source right now, but the clincher was receiving info that a toxin in Bracken bioacumulates.

    Boy, when I saw today’s offering it took me right back to my childhood. We (my friends and I) used to pull them up by the roots, and strip off the foliage, and throw them like spears. Somehow we knew to not throw them at each other. Never ran out of a good supply.
    Thanks for the memories, as Bob Hope used to say.

    The backlit bracken takes me back to when I was a child. I used to walk through the woods in the arly morning or late afternoon. The forest floor was solid ferns, all backlit. It was a fantasy like environment. Sweet memories!

    ferns are lovely and grow
    in zone nine
    one may make fine art work with them
    and they dry quite nicely
    i loved the ferns in a pot placed
    on or in a tall planter in the front
    room sit and read or chat

    Back in 1964 I completed my PhD using bracken fern as an indicator of site productivity for several tyree species at the University of Michigan. I am delighted that the plant again receives some attention. It is certainly a plant with personality and its indicator value for site productivity needs further work. The species has two subspecies, judging by what I knew back in 1964 ande no local rases were segregated out. As I travel the world I see it everywhere. It is like meeting an old friend again and again. It makes me feel at home everywhere. Thank you for the pictures and notes.

    It is so to see these Fern Photographs. The forest floor is so nice with them. It is like a beautiful blanket.
    Thank you.

    Pteridium aquilinum, composed of several subspecies, has a very wide distribution but is not cosmopolitan. North American bracken is essentially referable to the variable subspecies latiusculum.
    The genus also contains other species, each with a distribution of its own.
    Several research groups work with the taxonomy of the genus. Professor John A. Thomson from National Herbarium of NSW and the Royal Botanic Gardens (Sydney, Australia) is the world authority. He works with morphometry, nuclear genome, and chloroplast genome.
    Cheers, Harri

    Please review article about evolotion stem of dicotyledons.

    In regards to edibility, quoted from The Encyclopedia of Edible Plants of North America by Francois Couplan, Ph.D. page 22(bottom)-23(top):
    “Raw young bracken fern fronds contain a carcinogenic substance, ptaquiloside. In Japan, a link has been made between esophagus cancer and the regular consumption of bracken fern. They also contain the enzyme thiaminase which destroys vitamin B-1 in the body. Young bracken ferns must therefore be cooked (preferably i a change of water)…”
