Title: Acer palmatum 'Sangokaku'
Post by: JRob on July 18, 2014, 10:51 AM
I have been so inspired looking at Bill Valavanis' "Classical Bonsai Art" i stopped at a local nursery and hunted for a Japanese Maple to attempt to duplicate his process and techniques. I picked up an Acer palmatum "Sangokaku"for $59.95. The tree I have is even loaded with seeds that I'll harvest and then sprout. When my son eventually takes over my collection this will be a nice tree for sure. If you are not familiar with this variety here are a few pic of the foliage and trunk. Striking color don't you think. JRob

This is quite an inspiring book that I find myself rereading every couple of weeks.

I like this variety as it displays the contrasting coral and lime colors.

You might be interested in the Sangu Kaku thread in on the Japanese Maple board here.  This twin trunk I have worked on for 20 yrs.  The coral color bark lessens with time, present on new growth, best in winter. Bark mostly light grey now, will whiten if I lime sulfur in winter.  Leaf color best is spring and fall, plain light green in summer.  Pleasant tree to work with, one of my first starts, also from nursery stock.  Nebari will bulk up nicely, if you get good radial root spread early, let it grow in shallow pot or ground.

Josh, I have viewed your tree many times since it was first posted several years ago. It first spiked my interest in this variety and was the reason I had added it to my bucket list of trees to acquire. It is a beautiful specimen and a fine bonsai. When my collection passes to my son, it is my hope after this spring air layering project, he will become the care taker of an equally fine specimen. I'd love to see more of your trees on this forum.

Look forward to posting more trees, second only to getting my twin 8 yr old twin boys interested in bonsai.  The maple in question is one of my son's favorite.  I've told him it is his to care for when he is ready.  Still working the picture thing, posting, etc.  Fun when it works!

Rob, we bought a garden size one about 10 yrs ago in Ca.  We brought with us to Chicago and planted it.  Did fantastic till this spring when it was leafing out, and we had a cold snap, and killed the entire tree exc. right above graft joint.  5" trunk and 7' tall.  Dead in just 2 wks.  We are pretty upset about loosing this, def would've thought having it in the ground would protect it, and it did for 3 yrs till last yrs awful winter.  I'm mentioning this to let you know this coral bark variety is very cold sensitive!  I too love them ;)

Random reading of info published on japanese maple nursery websites that specialize in maples for landscape (not bonsai centric). Sangokaku is noted for being a problem maple in the northern half of the JM range. There are other coral bark maples that perform better.

Rob, you have a resource near you, perhaps you have been there. I bought a what I think will prove to be a great maple for bonsai  - 'Hime Shojo' from Davidsan's Maples, New Berlin IL, I think it is just north & a little east of Edwardsville, IL. ( Only down side is he is landscape orientated, 95% of his trees are grafted. Though he does keep a stock of no name JM from seed. I browsed this pile in middle summer, looking for a seedling that had leaf color different than green in the middle of summer. No success, but will check every time I drop in there. If you are not familiar with this nursery, you should check it out. I enjoyed talking with them and visiting when I picked up my order.

Talk with David, he is incredibly knowledgeable about the traits of various JM. He steered me to Hime Shojo, and I could not be happier - it is a dwarf, in many ways like Koto Hime for growth habit, but it is a coral bark with a reticulated red pattern in the leaves that holds all summer long.
