Japanese Sunrise

5 years ago

I was wondering if anyone has one and could show me pictures and tell me your experiences with this variety?

It sounds wonderful and beatiful but it always means more when I can hear from people who actually might be growing this variety.

Or! If you have a suggestion for a Japanese Maple that would be about 15-20 ft tall and vase shaped that they could recommend I would welcome those suggestions as well. (I want to stay away from the red/burgundy ones since I have one nearby where this new tree will be going.)

Japanese Sunrise, like all of the colored/red bark JM's, has an increased susceptibility to bacterial blight, Pseudomonas syringae. It seems there is something in the genetic make-up of the trees with colored bark that makes them more vulnerable to this pathogen. It is encouraged by cold winters and cool, wet springs so selecting a JM with this sort of coloration depends a lot on climate :-) It seems to be most prevalent on young trees.........once established and over 6-8 years of age, even the colored bark selections are less prone. It is typically identified by blackened tip dieback or black lesions on the bark and if not addressed and removed, can cause death.

'Japanese Sunrise', 'Sango Kaku', 'Bihou', 'Fjellheim', 'Beni Kawa', 'Winter Flame', 'Aka Kawa Hime' are all more susceptible to this issue than JM's with "normal" colored bark. So also is 'Corallinum', but that's another discussion :-)

Gardengal, that was my fear about the disease susceptibility. I would absolutely hate to lose it after a few years. My mom has a beautiful old coral bark maple that she lost a portion of to last year to disease.

Do you perhaps have any recommendations for something that has some of the characteristics of the one above? We do have the deep red maple nearby to where we plan to place the new one so would love something that would complement that. Right in front of the maple is also a dogwood tree.

Sorry about the woodpile. My husband cut down a few trees and is giving the wood away but the people haven’t come to pick it up yet. I told him it is messing with my aesthetic :/. But at least the sweetgum trees are gone!

I would consider 'Orange Dream', Katsura, 'Linearlobum' or Seiryu'.

I don't know how you feel about yellow fall color, but the green-barked maples Aoyagi and Ukon are not disease-prone and they make a great contrast to red-leafed trees. Aoyagi grows more vigorously than Ukon. The leaves may burn some if kept in full sun.

Mens, I love yellow colored maples as well and so does my husband. That could be a really nice pairing, I think. I will check them out and thank you for the suggestions!
