At a plant nursery in Gresham, OR in 2007 I bought this tree after the nurseryman said it would grow in North Iowa. For almost 4 years it has been growing very well in a sheltered location between the house and garage. It is subject to afternoon sun which doesn't seem to bother it. ( Maybe just minor wilt.) In early October after a major frost the tree is covered with leaves until mid April when the temperature climbs to the 60's. After the leaf cover is removed, there is hardly any die back noticed. The only disappointment about growing the maple is not seeing the bright red color in Fall, because I cover it too early while the dark leaves remain on the branches. If I waited for the color to appear and the leaves to fall it might be too late to protect it from the cold. With this ... read more

This tree looks like a fountain growing in the shady wfront of our western facing home. From year to year we never know how deeply red the foliage will become, but we can count upon a bright crimson fall display. Spring of 2010 was the first time in the tree's 18 years in this spot when its leaves did not sprout in the spring. A local nursery told us this was true for this cultivar throughout the area because of the early and frequent frosts. However, it did come back into foliage by June. Once again this tree proved itself to be a survivor, growing as it does in our sandy landfill.

I planted a Acer palmatum var. dissectum on the north side of mine and my next door neighbor's house. We live in central New Jersey which is zone 6. The first year our trees thrived and supported full, lush leafage. We suffered through a couple of 24" snowstorms this winter. When our trees started to leaf out this spring, both our trees
presented with a bizarre leaf pattern. Only one half of the tree leafed out on both our trees. We both have suffered with vole problems in the past and was thinking could these creatures have gnawed the root system on exactly half of our trees or was the heavy winter snows to blame....Any ideas?

Have mine for five years. It sits atop the waterfall of my pond. it is a gorgeous tree and I have had no problems with it at all. Went from part shade to full sun after a tree was removed and it has done just fine.

On the color - it's a question of degree. While it does need sun to color up, I have had summers where it turned very green and others where it stayed mostly red. The spring and fall colors are spectacular.

A hardy cascading plant (to 10'...in 50 yrs!) whose finely dissected foliage opens deep crimson but changes to a drk-purple-red, which color it holds well through the summer until autumn's scarlet appears.PSh/Med

On the issue of leaf color, the more sun you give the tree, the deeper red or burgundy you will get. The leaves will get more and more green the shader it is.
