Help Choosing a Coral Bark Japanese Maple

18 years ago

Last week while at a nursery I ran into a coral bark japanese maple. I'd never seen one before and boy was it STRIKING. The specimen I saw was the Sango Kaku variety with bright red bark all the way to the ground and neon green leaves with blood red fringes.

Being the japanese maple lover I am, I MUST have one of these coral bark maples, but I can't decide which one I want. I know what I am looking for visually but am unsure which one to go with to achieve the effect. I'm looking for these qualities:

1) reasonably tall (at least 10', preferably more)

2) at least moderate growth rate

3) can be placed in part-full sun area (I have shadier spots available if needed)

4) the showiest and brightest red bark that continues over as much of the plant as possible

5) preferably non-red leaves to contrast with the bark

My concern with the Sango Kaku variety is that I've read only the new growth is red, then turns brown the next year. I would like all of the woody growth to be red if possible.

These are the varieties of coral bark I've been recommended so far:

Beni Kawa

Japanese Sunrise

Pacific Fire

Sango Kaku

I would love input on how these varieties fit what I'm looking for and even suggestions on varieties you think would be better.

Personally, I don't think you can go too far wrong with Sango Kaku. I'd just want to make sure I obtained mine from a very reputable source, as I fear there are some inferior growing operations out there that are mass producing this tree, perhaps not from the choicest stock and the end result is some rather inconsistant, ill-formed and disease-prone trees.

I bought mine 10 years ago. It has matured into a gorgeous, naturally perfectly shaped specimen (never taken pruners to it) about 18' tall. I've yet to see much redness on the leaves, even when first emerging and I'd describe the foliage color as a bright, grassy green. Fall color is a peachy gold.

The tree is stunning in winter. The entire crown glows red with only the trunk and the largest and oldest portions of the major branches more of a greeny-brown. It certainly is not obvious to me that second year growth looses color, in fact quite the opposite. It is the canopy and branching structure you notice when not in leaf, not the trunk, and this has retained its coral red color extremely well.

I know you said japanese maple, but you might also want to look into an American maple/German cultivar: acer pensylvanicum erythrocladum - the bark is stunning (red in winter, red with white stripes during the year, then turning slightly like sango kaku for a while) the leaves a great green throughout the year, and a luminous yellow in the fall.

Coral Bark Japanese Maple-Phytophthora root rot(?) -Please help!
Q

It was suggested "Exact diagnosis can be made by taking a sample to your local extension office but if it is Phytophthora (or another root invading fungus), there is little you can do now." If such a sample is brought to the Extension Service office, please call ahead so that the Master Gardeners have time to locate information as to how to sample the soil & the affected root tips. Also know that a fee is charged, the precise amount depending upon the test to be done -- fees for the OSU Plant Disease Clinic begin at $40.00. Beyond that, I doubt this will be an easy diagnosis. I'd consider multiple factors potentially contributing to the problem: 1. Because OP said s/he "paid quite a bit of money" I suspect it is a sizable specimen. If so, post-plant irrigation is a critical factor in survival. All transplants should go into evenly moist soil, then the rootball should be supplied with more water than the surrounding area during the following months. Failures of recent transplants typically are due to water -- either too much or too little. 2. The sudden very cold weather in December, without snow cover, damaged & even killed many plants hereabouts, including those which survived 10 years or more. 3. The tree is a recent transplant. As such it is more likely to be damaged by cold than an established tree of the same kind. 4. Dormant roots are less susceptible to water damage than are actively growing roots. 5. In general -- and yes, exceptions exist -- root rot results in entire tree failure. 6. It's nigh to impossible to diagnose root rot by looking at dead branches and/or browning leaves. 7. And perhaps most critical, multiple nearby specimen maples are in potential jeopardy if the problem is indeed soil-borne, such as Phytophthora root rot or verticillium wilt. So, I suggest pinkswine consider having a certified arborist or two come for an on-site evaluation. To locate a certified arborist, look in the Yellow Pages under the heading of Trees or something similar. Ads for companies with a certified aroborist will either have a statement or small rectangular logo stating such.

Coral Bark Japanese Maple - has strange shooters?

I looked at your pics. Cut that off. Every time you see a branch "whip" out like that, cut it back to the origin. Your tree is grafted. The long dark green leafed branches are growing from the bottom part of the tree, the "base" and not the grafted portion you want to grow. Normally, good grafts don't do this. Sometimes this happens, roses too. Congrats on your tree, it looks nice. I have a baby coral bark that I planted last September that has grown a little this year, I love the red barks in winter.

I obviously don't live in Toronto so can't comment about the suitability of this tree for that area. But I will let you know that colored bark Japanese maples are extremely prone to bacterial blight, Psuedomonas syringae. And this pathogen is encouraged by winter cold damage and cold, wet springs. Even in my very mild winter area, pseudomonas is common on these selections because of spring weather. And it can be fatal. I would site the tree so that it receives maximum winter wind protection and in whatever microclimate you can manage........any "L" formed by the house or other structure, reflected heat from a south facing wall or paved area or in the shelter of other larger growing (and preferably evergreen) trees or shrubs.

Coral bark Japanese Maple -where to plant it to avoid cold winter wind
Q

I don't think Japanese Maples are in the category of fussy garden plants, but are instead in the category of tough landscape plants. Neither can I imagine that there is any scientific study of wind tolerance applicable to this plant. Most of the information about that kind of thing comes from anecdotal stories which can be highly inaccurate or flat wrong. Usually one tries to satisfy a plant's known general cultural requirements (water, light, soil) but other than that, it's usually pay your money and take your chances. With landscape plants, the chances of success are usually very high. Of course one plant is never going to solve all of the problems in a yard. It's a matter of placing it where it will solve one problem. Other plants can go in other places and solve other problems. Of the options you've presented, I like position 1 because it has the potential to block the view of the sides between the neighboring buildings and because it is not overwhelmed by neighbor's plants. (BTW, if you picked a position where neighboring plants hang over into your yard, you'd probably need to cut off the overhanging portion in order that your tree would have a chance to grow without developing a profound lean to it. You have the right to remove what is encroaching from the neighbor's into your yard ... but only to the lot line.)

I have an A.p. 'Sango Kaku', which I do love. My only complaint with this tree is twig die-back in the winter. It seems very sensitive to cold winds. Color is wonderful, however!

Don't forget the green-barked compliment to coral-bark maples. These trees display brilliant lime-green bark in the winter: A.p. 'Aoyagi' (gets big like "Sang Kaku') and A.p. 'Aocha Nishiki' (smaller - 8 to 9 feet). Planted close to a coral bark, they will create quite a show together!

Don't forget 'Fjellheim', I have heard that the color retention on this cultivar is better than 'Sango kaku'. It is more compact although reaching 7-12 feet at maturity.

hi. i'm sorry if i brought up an old thread but i sure would appreciate some help. i am interesting in replacing a JM (died) with a JM Sango Kaku. what is the deal with the red/coral bark? does it stay red/coral? i visited a nursery last week and thought i had picked out a great one with the shape i liked and it's main stem/branch/bark was red/coral color. when i visited today, i noticed that the main stem of the tree was no longer red and more of a gray/greenish color.

does the red/coral bark lose its color in the main stem at specific times of the year or with age? or something. if i get one with a red main stem, will it remain red/coral?

thanks so much for any input.

Pretty much any of the "coral barks" (Sango Kaku is the original - the name means 'coral tower') will have the brightest bark coloration on the newest growth and in the winter. Oldest bark (trunk and eventually major limbs) will turn a duller greenish brown.

During summer or through the primary growing season, even newest stem color is not very pronounced, but hard to see anyway when tree is fully leafed. It is the colder weather of winter that really intensifies the color.
