    Re: Acer buergerianum 'Mino yatsubusa'

    Below are some of my crude photos I have along
    with me here (I am away from home) of my Acer
    buergerianum 'Mino yatsubusa'

    This Trident Maple was originally imported from
    Japan into the US in 1972. The original cutting
    grown Maple is still alive and currently resides in
    a private garden. 'Mino yatsubusa' was not seen
    anywhere in the US until 1980 when Don Kleim
    of Henderson Experimental Gardens gave two
    very young, grafted plants (3 year old grafts) to
    two grower/nurserymen in Canby, Oregon, to be
    evaluated by them exclusively and grown on. It
    was several years later that this Maple was outlet
    to anyone else in the US for propagation purposes.

    The section on page 151 of the Vertrees 2nd edition
    Japanese Maples book was supplied, as per request,
    by Mr. Don Kleim and edited by Mr. Vertrees.

    'Mino yatsubusa' was real tough to propagate until
    grafted onto 'Simonii' Trident. No other rootstock
    seemed to work well for this Maple for a number of
    years. I do not know all of the specifics of where the
    'Simonii' Trident Maple originated from but I do know
    this Maple became the standard rootstock for most all
    specialty Acer buergerianum on the West Coast for a
    number of years. This rootstock is not to be confused
    with Acer semenovii that was later used exclusively as
    a rootstock for the dwarf forms of Trident Maples in
    very select nurseries on the West Coast, most notably
    Maple Wood nursery in Placerville, California.

    The first two photos were taken 6 weeks earlier than the
    three other photos. As we can see the initial growth was
    rather vigorous, larger in size than usual in most years.
    Bear in mind our trees grown here are larger in size as
    well as our leaf sizes tend to be larger than anywhere
    in Oregon. The middle three photos show the newest
    growth scaling down in size but still a little larger in
    size and wider in the lobes than normal. If this Maple
    had been stressed a little the leaves will scale down to
    half the size of the newest growth as seen here. Each
    successive cycle of new growth will have smaller leaf
    sizes as the growing season progresses.

    This Trident grown here in lots of sun will turn a brilliant,
    almost illuminating deep scarlet red in the Fall with only
    the shaded interior leaves turning a golden orange color.
    Grown in morning sun here with afternoon shade the Fall
    colors generally will be an even shade of a light to strong
    golden orange with the exterior leaves turning scarlet. The
    more sunlight we give this Maple during the growing season
    the deeper and richer scarlet red we will see in the Fall.

    The last two images are of my 'Simonii' Trident. I realize
    there may be some confusion and doubt in the accuracy
    of the name but that is what Don Kleim called the Maple.
    No one I knew involved in Maples through discussions I
    attended with Don argued with him about the name either.
    They all seemed to know this Maple rather well.

    This Maple when allowed to grow was extremely popular
    for bonsai enthusiasts as the leaves will scale down to
    fingernail size and smaller in a bonsai pot rather soon in
    the plants age and development. These Maples just flew
    out of the nursery when they were offered for sale as
    bonsai plants but were only offered for sale to bonsai
    specialists through regional bonsai club and bonsai
    chapter affiliate meetings held at the nursery.

    As a matter of fact, my plant had been in bonsai pot for
    about 5 years. The leaves at the time I bought it were
    no larger than fingernail size then. I took the Maple out
    of the pot and placed it in a 5 gallon container for almost
    8 years and then planted it in the ground in 1990. The
    Maple now is over 35 feet tall.

    I am an avid grower of Bonsai trees in Florida. I participate in maintaining the large Bonsai tree collection at The Morikami Japanese Bonsai Garden in Delray Beach, Florida. There are several northern trees that grow successfully in Florida. One that I find rewarding is the Trident maple. Your article on the Mino Yatsabusa leads me to believe that this would be a fine addition to our collection and to mine, as well. Please tell me where I can obtain specimens of this tree. Thank you for your assistance. Ron Kessler

    Mino yatsubusa is an outstanding small tree for a garden and its fall color is even better.
