    A few weeks ago a friend of mine ran across scions of a cultivar labeled as Koshimino Nishiki and gave me two of them. At first, I thought this was a mislabeled scion. After getting Vertree's 4th edition in the mail and finding it listed in the "other maples not yet studied" section, I changed my tune about this cultivar. I ended up grafting these scions and the buds on these two grafts are about to burst open. Does anyone know anything about Koshimino Nishiki? Do you know how tall it gets or what distinguishes it from Hagoromo?

    Koshimino seems to mean "straw raincoat" and from the "nishiki" it sounds like it may be variegated.

    Thanks chimera,

    I was thinking something along those lines... maybe something similar to Hazeroino. Nishiki aslo means brocade or rough according to the 4th edition, so it definitely has my interest. I can't wait to see the tree leaf out and watch its characteristics.

    I have been waiting and hoping to see something that would distinguish 'Koshimino Nishiki' from 'Koshimino','Hagaromo', or 'Momenshide'. Thus far I have not found anything. Here are some pictures of the grafts in July. They have looked similar all year long. Maybe in a few years they will destinguish themselves like 'Hazeroino' or maybe 'Nishiki gawa'. I'll keep you updated.

    Note* I have been hesitant to post these in the picture gallery as a new cultivar because of the likelyhood this could end up being synonymous with 'Koshimino'.

    The old form Koshimino was affectionately called Fish tail.
    The old form plant was pretty much left on its own roots
    for many years. Was not grafted at all until the mid 80's.
    No need to graft it as the old form plant from Japan yielded
    seedlings pretty much true to type. Even many seedlings
    that came about from grafted parents on matsumurae and
    palmatum rootstock pretty much retained the leaf size and
    shape of the old form Koshimino. Depending on the amoenum
    rootstock used there could be some variability in the leaf
    sizes and leaf shapes that were not so readily seen with
    matsumurae and palmatum rootstocks.

    There have been some seedlings from old plants that did
    not have the same growth habit as the old form plant which
    is pretty much an upright growing tree, usually a lanky,
    single leader with short in length lateral side shoots.
    The old form plants did not grow very wide at all much of
    the time. A good sized plant might be 9-12' tall and about
    2-3 feet wide - I've seen many in this size frame. We grew
    seedlings pretty much as giveaway plants (at no charge)
    to collectors and specialized Asian motif landscapers that
    wanted them. The seedling plants were never were offered
    to the public for resale otherwise. Grafted plants on the
    preferred matsumurae rootstocks were offered for wholesale
    and retail sales however.

    It was conceivable years ago that this Maple could have
    variant forms of which a nishiki form, in this case a form
    that is more compact in its growth habit and perhaps more
    twiggy and wider growing than the old form could have
    come about. I've seen some seedlings from an old
    parent plant on its own roots do this whereby they
    could be 9 feet tall at maturity and be 4-6 feet wide
    and be even shorter and more compact than this.
    In Japan a hime dwarf form was selected out years
    ago and I believe a nishiki form came into the US in
    the early 70's but was not called Koshimino nishiki
    at that time.

    What may be fun for someone to play with is to
    take Hagoromo seed from a parent tree on its own
    roots or from a one generation (filial first generation)
    grafted Maple and use these seedlings as a rootstock
    for Momenshide, Hazeroino and Koshimino and see
    what you come up with in time. I do know some
    attempts to yield more red coloration in Koshimino,
    Hagoromo and Hazeroino have been conducted
    using Burgundy Lace seedlings and even rooted
    cutting rootstock that yielded some interesting
    colored seedlings from those grafted trees.

    I see no real problem posting this thread in the
    photo gallery. By the looks of the last photo
    this is not your typical Koshimino by the top
    growth and leaf color shown in the photo.

    An added note: yes, there was a Pine
    Bark Maple that was also a member of
    the ribbon leaf group but it was not a
    Nishiki gawa. Inasmuch as Koshimino,
    Hagoromo, Hazeroino and Momenshide
    may not have true ribbon leafs, they were
    placed in the ribbon leaf grouping at one
    time due to their very short in length petioles
    and the fact that whorls of shoots can be
    seen emanating from single, compound
    buds at the terminal tips, just like true form
    and now so very rarely seen ribbon leafs.
    Even some true thread leafs were also
    considered to be ribbon leafs at one time
    as well due to their very short petioles
    and terminal tip whorls. Look at Mr. Yano’s
    photo of Yori ito and tell me what you see
    from it - a throwback to the old ribbon leafs
    with a latilobatum shaped leaf - fascinating

    Wow. Thanks for all that good info Jim. Great stuff. This is Tim's brother and I am glad to learn more about this cultivar.

    Very good post.

    Thanks so much. I am enamored by the ribbon leaf type maples and you just made my day. I have been trying my darndest to figure out more about these trees. I appreciate you taking the time to share.

    I may have to try some experiments similar to those that you mentioned.
