cultivar of a Shantung
maple is called Fire Dragon® Maple and
was discovered and introduced by Metro Maples.
A medium-sized shade tree that only grows to 25-35 feet after many years
and can take the hot Texas sun. Regular Shantung are
also great maples that are very similar and explained below.
Fire Dragon® is the most consistent
and reddest Shantung maple (and perhaps the reddest fall color of
any maple) that I have ever seen, and was
selected from among the twenty-two thousand seedlings I have grown. It
also has a near perfect leaf shape that makes a more elegant and
cleaner looking tree.
Shantung maples are in high demand and are gaining
popularity in 49 states. This tree will prove to be "tougher and just as beautiful as
any maple growing back east". Hardy and heat tolerant, it
just about anywhere in acidic or alkaline soils. Over 6,000
Fire Dragons sold since the 2006 introduction!
In 2008 in Tokyo I met a Chinese botanist, professor and author and had
him pronounce Shantung. He pronounced it Shan-doon. The
second syllable rhymes with moon and is slightly higher in pitch.
This is a
close-up of a Fire Dragon® leaf
in the fall. I have it patented (PP #17367) because of its superior fall
color and great leaf shape. It's full name is: Acer
truncatum 'Fire Dragon®'.
METRO MAPLES INTRODUCTION - FIRE DRAGON®
MAPLE, PP #17367.
THREE HUGE FACTS: (1) 3 days of
freeze, each down to 24 degrees and not above freezing in NW Arkansas, in mid-April, did
damage to 'Fire Dragon'® but defoliated
all the oaks and other maples. This event killed 3 years of growth
all the way to North Carolina. (2) 2011 was the hottest, driest,
windiest, worst Texas summer of all time and yet 9 for 9 'Fire Dragons'® survived
and colored up normally in the fall without irrigation in my dry sandy soil. (3)
Shantung maples were top performers with the least damage from the
terrible ice storms in Oklahoma.

The leaf is so distinctive, even when solid green, that I am always able
to pick out this tree from regular Shantung maples.
The new growth colors are from pigments that might help protect the new leaves
from ultra-violet rays or from insects, until the leaf has a chance to photosynthesize
or produce tannins to ward-off insects. Spring colors are awesome

Japanese Maple in 2003. First grafts of Fire
Dragon® were done in 2002, but when I saw this color I
decided to patent this tree. Perhaps the reddest fall color of any
maple in the world.

Reports have come in saying that Fire Dragon® turns red from Oregon, New York, Virginia,
to Arkansas and Oklahoma, and even

consistent red for hot, sunny climates has never been achieved until
now. Here is 'Fire Dragon'® Shantung in the fall of 2007 with Ginkgo
I call this color red-red and it makes all
other maples look purple-red or orange-red. Most shade
trees that turn red in the northern parts of the USA never
produce red in Texas. Do not confuse a Shantung with Sugar maple, Red, Silver or any other maple you have heard
about. This maple is totally different and you'll be amazed at
its beauty and toughness and other great qualities.
In 2009 I saw a new fall color for 'Fire
Dragon®'. After 27 inches of
rain in just the last 10 weeks, and endless clouds, and the first actual
fall feeling temperatures in many years, some turned a brilliant orange,

with red color in 30mph winds.
There are at least 3 different red anthocyanin compounds
that can form in the fall based mostly on temperatures and length of
chilling, and soil pH does not seem to affect the color. I have
seen bright cardinal red, currant red with Chinese yellow margins, and
reddish-orange, but never yellow unless it turns fall color early
due to stress.
Another cool thing about this tree is that fall colors
are consistent on every branch and leaf, and color
is not much affected by clouds or shade or high/low temperatures or soil
pH. I get this same color even underneath the native post

A dark, glossy-green summer color. To me when they shine in the sun
they look like
green diamonds. Shantung maples have a very efficient root system that
is not aggressive, a waxy and thick leaf, and low transpiration rates to
help them through hot summers.
Shantung maples might grow to 35 feet tall and wide with age in the
lower midwest. They grow faster and get a little bigger in warm
climates than those grown farther north.
They are hardy
to at least 25 degrees below zero.
Shantungs were one of the
very few trees that had no damage
from the huge late freeze in April
2007 across the midwest to North Carolina that destroyed 2 to 3 years
worth of tree crops.
Shantungs are not messy and will drop all leaves and cover the
ground with color. They are easy clean-up compared to other trees
and decompose quickly. Here are regular and Fire Dragon®
leaves after leaf drop.
Acer truncatum has been used as a street tree in Shanghai for
many years, tolerating the pollution, limited root space, and compacted
soils. In the difficult DF/W climate you should give your Shantung

expected to live 250 years or more.

Here is a
picture of an Acer truncatum, Shantung Maple that I photographed at the Morris
Arboretum, PA. It is a beautiful tree, grown with its natural low trunk shape. It
was at the Arboretum at least by 1916 but probably there in 1906, making
it 100 years old when I took this picture.
Somewhere in its history a low branch was removed from the right-hand
side to allow clear passage on the road. Pictures taken from the left
side did not reveal branching, only foliage.
The tree was 35 foot tall and 35 foot wide. Main branching occurred at 2
feet. Trunk diameter is about 2 1/2 feet. No surface roots or decay
In 2011 after the 4th International Maple Symposium in Belgium I
traveled to Kew Gardens in London and photographed this Acer truncatum.
Most likely this is the tree in Maples of the World that stated
was the first A. truncatum
out of China and went to Kew in1871, making this tree 140 years old.
The top of the first branch crotch is 6 foot off the ground!
Estimated height and width is 38 x 50 feet. The trunk at ground
level was 3 feet thick.
Here is a
variegated Acer truncatum that I found. I have many other test plants and hope to
introduce more cultivars as soon as possible. Some of the most
likely prospects are pictured in 'More Maples'.
spring blooms are bright and very nice on Shantung maples and
this picture does not do it justice. Most
observed flowers are male flowers so seedlings have not been a big weed problem.
When you compare a Shantung maple to other shade trees it will always
come out on top. It takes the heat, cold, wind, ice, bad soils, doesn't
get too big, doesn't have surface roots, is long-lived, nice blooms,
nice looking bark, nice leaf, doesn't produce many seeds, and has brilliant fall

of a Shantung maple can be affected by its location but will eventually
become rounded when given the room to spread.

managed to produce very nice color on November 22.
They were red-red in Oklahoma, Arkansas, and

There are several garden centers and especially home improvement garden
centers that are selling inferior maples that are labeled as Shantung
maples. The two top left leaves are Shantung maples. The top right is a
Norway maple that had a Shantung tag. The lower left leaf is probably a
sugar maple that had a Shantung tag. Neither the Norway or Sugar maple
are good trees for alkaline soils and will grow for only a short while
and will not produce much fall color. Both the Norway and Sugar maple
have smooth gray bark, whereas even a small Shantung will show some
fissured bark and should be brown. If you purchased one of these
mislabeled trees I recommend you return it immediately.

Shantung I have personally grown over 20 years: 23,750)
This Shantung (ten years old as shown) was grown from seed in 1995 and planted in the year 2000
as a test. It proved to be drought tolerant through that record-breaking
hot and dry summer without irrigation (110 consecutive days without
rain), even though it was planted in the dryest possible place, the top of a pure sugar-sand hill.
Texas A&M has designated the Shantung maple a Texas Superstar®.
Kansas State University has performed trials and declared it one of the
best ornamental urban trees. The United States Department of Agriculture
is currently researching Shantung maples and my Fire Dragon®
Shantung to introduce tough, reliable, and beautiful trees that will not
out-grow small urban yards. Oklahoma, Missouri, Utah and Minnesota and others have given their
approval. Nobody has ever rejected this species as
unsuitable. The future looks very bright for Shantung
"Growing the Shantung Maple in Texas Conditions"
written by Keith Johansson for The Maple Society newsletter,
published Summer, 2006.
Acer truncatum, Shantung maple, is thriving and gaining
popularity in difficult situations, like the Dallas/Fort Worth, Texas
area. I began commercially growing fifty plus varieties of Japanese,
Shantung, and other maples in Fort Worth in 1994 under the name Metro
Maples, but now I love the Shantung maple because of its toughness, good
growth, and year-round beauty. Dr. John Pair, Director of Research,
Kansas State University, told me back then at an American Rhododendron
Society meeting that I should grow Shantung maples. He was one of the
most respected horticulturists in the country and did the initial
research on the tree in Wichita, Kansas from seed sent from the Morris
Arboretum. Not only does Wichita get hot but it also receives severe
cold snaps and strong winds. Many reports on the Internet claim the
Shantung maple is cold hardy to at least minus 25 degrees Fahrenheit. In
early December 2005 none were damaged by a sudden change from 90 degrees
to 14 degrees, while many Japanese maples were damaged or killed.
Initially, Shantung maples were hard to sell, as nobody knew what they
were. To me it seemed like a tough and beautiful tree but many thought
it might be another Silver maple that falls apart quickly in my area. By
year 2000 the Shantung maple and only two other trees were on the Texas
A&M University Superstar list and sales took-off.
I have grown approximately 9,000 Shantung maples, which seed comes from
China with a climate similar to New York. They are easy to grow from
seed. Shantung seedlings have grown fast in the first year but lately
they have grown slowly. I believe recent seed was harvested too soon.
The average person with an established tree will get growth of 2 to 5
feet per year even in the alkaline black gumbo soils of Dallas or the
white caliche soil of Fort Worth.
They are extremely drought tolerant as I have watched several survive
without water during my very long and hot summers in my sandy soil. In
my area they do require irrigation for the best growth. In summer 2000 I
went 110 days without any rain. Last year was the worst drought in fifty
years and I began watering my larger trees in summer, once a month to
maintain good health. I have grown thousands in full sun in black pots
on black plastic and can get new growth, which does not burn, from April
until the first of September. Shantung maples must like it hot and
somewhat dry as my extremely sandy soil never holds any water and
dries-out very quickly and because for me they reach over 20 feet in 7
The only native maple in my area is Acer negundo but is not a tree for
most people. To the east and southeast where soils are acidic and
rainfall more abundant is Acer rubrum and Acer saccharum spp.
floridanum. To the south is Acer saccharum ssp. grandidentatum. In
western Oklahoma there is a sugar maple that has survived the
millenniums in a small canyon that is called the Caddo Maple. These all
grow for me but are slower and are not quite as showy or as tough as the
Shantung maple branches are flexible but old wood is very hard, much
like an oak. They can grow in windy sites. Kansas State University
proclaims them also as one of the best performing trees in ice storms.
The bark is two-tone brown, heavily fissured and very attractive. The
root system reminds me of a Japanese maple and is not overly aggressive
or shallow rooted. They tolerate pollution and fit the typical urban
landscape. About the only thing they cannot tolerate is poor drainage.
The bright lemon yellow flowers are produced in corymbs and this year
one large tree had flowers for 10 days before the leaves emerged.
Usually the flowers appear only a couple of days before the leaves. So
far it appears that most seeds do not develop for me but this means that
the tree is also not weedy.
Spring and summer new growth is usually a reddish-purple, but reds and
oranges are also seen. Fall color is a very bright yellow on about 90
percent of the trees. Sometimes reds and oranges are mixed with the
yellow. Sometimes they are all red or orange but return to yellow the
next year except for a new introduction I call Acer truncatum ‘Fire
Dragon’™. This tree has always had red fall color. The other reason
I choose to patent and propagate this variety is the beautiful leaf
shape (see photo). ‘Fire Dragon’™ has smaller leaves that are
seldom truncate and have backward angled basal lobes, lobes with
prominent teeth, and do not have the larger central lobe that is typical
of most Acer truncatum. The size and shape of the leaves give the tree a
cleaner look. Summer growth can be a burnt orange or pink or bright red
depending on the nutrients and the amount of water. Fall color is a
cardinal red (RHS 822/3), or when I don’t have cool temperatures it is
a currant red (RHS 821/3) with striking Chinese yellow (RHS 606/1)
around the margins. ‘Fire Dragon’™ also appears more heat tolerant
as it has a good ability to keep healthy new growth without wilting
under extreme heat conditions. What seems so amazing is that 4 years ago
I had just one small mother tree, and now I have over 3,000 of them!
One of my first Shantung seedlings I grew is now 12 years old and turned
out to be a nice little dwarf. It is always growing, trying to be big,
but is only 3 feet tall by 3 feet wide. Its leaves are only 1 inch wide
and new growth is a very attractive orange-red all summer. I call this
tree, ‘Baby Dragon’. I have no plans for production but I do have
some safely tucked away in another location in case a tornado takes mine
I am also testing two yellow fall color cultivars. One has very narrow
and wavy leaf lobes giving the tree a delicate appearance. This one is
called ‘Skinny Dragon’. The second tree produces a high percentage
of beautifully shaped leaves with backward angled basal lobes and teeth
on all the lobes, which is known as ‘Golden Dragon’. All Shantung
maples have polymorphic leaves in varying percentages. These two are not
any better or worse for fall color its just the beautiful leaf that is
desired. There are also several other interesting leaves that I have
found including one that has deeply cut lobes with side lobes that curl
downward, (see photo). My seeds produce leaves that are similar in shape
to ‘Golden Dragon’ about 30 percent of the time. Hopefully, soon I
will find a dissected leaf. I have two new variegated seedlings under
review. One does not grow much at all and we’ll see what the other
does. Recently I grafted an Acer platanoides ‘Crimson King’ onto a
Shantung rootstock to see if this tree will then grow in our area.
I’ve thought about what I could hybridize a Shantung maple with but
there aren’t many improvements needed.
Texans love fall color. Unfortunately the native trees, mostly oaks,
hackberries, cottonwoods and pecans have poor fall color. They love
Japanese maples but they must be shaded and carefully watered. Shantung
maples act like a native and turn brilliant colors every fall. I am now
planting Shantung maples all over the farm so when I retire they’ll be
ready to put on a really big show that you’ll have to see to believe.
"New Acer truncatum Cultivars"
written by Keith Johansson for
The Maple Society newsletter - published Winter 2011
dreamed that the range in sizes and colors of Acer truncatum would be so
vast, and in the beginning never went looking for new cultivars but they
came looking for me. I have
been growing Shantung maples for 17 years and now have 17 distinct
Shantung maples that are grouped into categories:
red or unusual fall color, dwarfs, mid size less than 15
feet (5m), columnar, yellow leaves, and variegated.
Here are two new cultivars to compliment ‘Fire Dragon’®
Shantung (PP #17367) that I introduced in 2006.
Acer truncatum ‘Baby Dragon’ (PPAF)
was discovered in 1994 and despite its fast growth is only 5 feet tall
and a little over 6 feet wide (147.3 cm x 185.4 cm). This
dwarf has a weeping habit as the thin branches are unable to hold up the
vigorous and dense leaf growth. Caliper
is just 2 inches (5.1 cm) and the bark is not heavily fissured.
Bark color is light gray, almost white, due to its slow caliper
growth rate. Average leaf
size is less than 1 inch (20.2mm x 23.1 mm) and a light green on both
sides. It is never a dark
shiny green like most Shantungs. The
veins on the underside are more prominent than usual, in part due to
their relative size compared to the leaf size.
The 5 lobes are slightly wavy with margins entire and triangular
ovate lobes broader at the bottom and deeply cut two thirds of the way
to the leaf base. Some bases
are truncate but the majority is shallowly heart shaped.
The petioles are slender and a short .7 inch (17.7 mm), and
maintain a light pink color on the upper side.
Milky sap is produced when broken.
Flowers or fruit have never occurred on ‘Baby Dragon’ but I
expect the faster growing grafts to eventually produce seed.
A 4 year old graft is already 4 feet by 5 feet.
New growth colors are easily
produced and are rusty deep pink to vivid strong pink. (Ed. - Photograph
of 18 month old grafted plant in July).
Fall colors are a very bright yellow and red.
This maple is heat and sun tolerant, and like ‘Fire Dragon’®
has shown an exceptional ability to avoid damage from early or late hard
freezes when in full leaf.
Acer truncatum ‘Super Dragon’ (PPAF)
was discovered in 2006 and has a brilliant yellow green leaf with light
yellow green veins that appear white.
Each spring the leaves unfold a moderate red orange with light
orange yellow veins. Summer
growth colors are bright pink, orange, or red, all with light yellow
green veins. The
yellow color never fades but deepens a little into summer (Ed. – photo
of July mature leaf detail over new growth).
Unlike other yellow leaf trees it does not easily burn, even in
the hot Texas sun. Fall
colors are a bright yellow with red.
‘Super Dragon’ has a slightly
smaller than average leaf size with truncate bases and wavy margins.
The central lobe usually produces large, broad triangular teeth
that also can occur on one or both neighboring lobes.
This cultivar has identical leaf colors on both sides.
Current year wood and petioles also display the leaf colors.
Winter shoots and buds may have yellow and red color but of a
darker tone. Like other
Shantung maples it is a low branched, shrubby tree but is easily trained
into a straight trunk. The
growth rate on this cultivar is a little below average so I expect this
cultivar to have a smaller mature height of about 25 feet (8 m).
‘Super Dragon’ should be hardy like other Shantung
maples, and along with ‘Baby Dragon’ will be important parents in my
hybridizing program of straight Shantung maples.

Chaos With Acer truncatum"
written by Keith Johansson for
The Maple Society newsletter - published Summer 2013
Creativity is a chaotic process.
There was chaos in Beethoven’s life, which included deafness
and was revealed in his moving 52 times and still never finding the
right place. We also see
chaos in Alexander Flemming’s discovery of penicillin in a pile of
dirty lab dishes. Acer
truncatum, Shantung maple, can also be creative when exposed to chaos.
In Texas I have frequently seen unusually hot summers the last 12
years. I try to grow most
Acer truncatum in containers in full sun on a west facing slope.
The soil is sugar sand and when the air temperature is hot I have
recorded the temperature of the sand just below the surface at 147
degrees Fahrenheit (63.90C).
Checking the inside of the black plastic containers halfway down
it can be 125 degrees F (51.70C).
These are not exactly ideal growing conditions.
In studying the growth of seedlings in response to this weather I
believe that I am now seeing Acer truncatum trying to adapt.
There is always something good that comes out of every bad and in
my case the good is true dwarf Shantung seedlings, now by the hundreds.
I first noticed in 2010 that 10 percent of my Shantung seeds were
dwarfs, which I thought to be more than just a chance occurrence.
Then the year 2011 was the longest, windiest, and hottest summer
ever in Texas. This
spring the seeds produced after that terrible heat wave have germinated
and now nearly all the seedlings look like dwarfs.
This substantiates my thinking that the trees are adapting by
producing offspring with very small leaves and miniature mature sizes to
save water and better survive the heat.
Most of these dwarfs have small 1 inch to 2 inch leaves that
resemble English ivy. The
branches are very thin and difficult to graft, and the buds are so small
they are hard to see with the naked eye.
There are various growth habits including cascading, spreading,
upright, or bushy upright to bushy with curving branches.
They are similar to the dwarf Shantung maple ‘Baby Dragon’ (PPAF)
that I found in 1994 but these have different shapes and they have red
fall colors. I plan on
introducing several of these in the future as they will be useful for
foundation plantings or rock gardens in hot sunny locations.
While we wait on the new dwarfs there are ‘Green Dragon’ and
‘Sugar Dragon’ Shantung maple cultivars to add to the ever growing
list of diversity I have found from growing over 22,000 of these
beautiful, adaptable, and heat tolerant trees.
‘Green Dragon’ is a slow growing, smaller Acer truncatum that
develops very heavily fissured bark, more so than any other I have seen.
Current year shoots are thick and show the beginnings of the
corky bark near the end of the first year.
The original tree is 12 years old and very upright and only 12
feet tall when some Shantung can be 25 feet tall in that amount of time.
Most leaves have truncated bases but about 10 percent show
backward facing basal lobes, which I discovered to be an indication of a
tree’s size. ‘Green
Dragon’ is usually bright yellow in the fall, sometimes mixed with
orange and red but the main features are its very corky bark, small
size, and heat tolerance.
There are several more Shantung maples under review that only
grow to 15 feet and can take the hot sun that I have grouped into a
‘Shorty Shantung’ class of test plants.
They all have various amounts of backward facing basal lobes.
The correlation of the basal lobes to slower growth was first
noticed on a true dwarf named ‘Hubble’s Dragon’, after Scott
Hubble who works with me. He
wanted to take this tree home to use in bonsai but I wouldn’t let him,
so instead I named it after him. ‘Hubble’s
Dragon’ grows 6 inches a year and is also very upright.
Leaves are much smaller and different than normal, and are
5-lobed with two over-lapping, backward facing basal lobes, and 2 lobes
that are usually at a 90 degree angle from a broader central lobe.
‘Sugar Dragon’ is a variegated cultivar that is yellowish
pink and creamy yellow in early spring.
This changes to various intricate patterns of green and white on
every leaf. The variegation
is stable all year and so far has never reverted.
This, like all Shantung I have grown, can take the hot Texas sun
without burn. It is expected
to be a mid-sized tree up to 15 feet.
Acer truncatum appears to be a thinking tree, even without having
a brain. You can see their
thoughts that are expressed in their growth.
Under chaotic weather conditions it also seems they can produce
lots of better adapted offspring and in a very short amount of time.
I am currently introducing a yellow leaf Shantung maple
cultivar, and since I already have a columnar form and various other
forms and dwarfs, all I need now is a red Ieaf and a dissected leaf to
complete the full range. Now
if only somebody can tell me how to get the dwarfs and the yellow
cultivar to bloom I will get busy with spreading some pollen.
