Hi Creativeslime, I understand that Eucalyptus is widely grown in forest plantations in your country, is that right?

It would help to see a picture of the entire plant or, at the least, a description of the entire plant. The 6th (I think) image -- darkish leaves -- may be a flowering crabapple. And consider posting in the Name that Plant Forum http://forums2.gardenweb.com/forums/namegal/ Here is a link that might be useful: images

If you still have access to the tree, a species level ID might be possible. It would help to know where the tree was (country, etc). Google 'Dombeya key' (those two words, not the quotes), and at least a few different keys (instructions for ID) will show in the results.

Impressive amount of thought and work going into this ... I will enjoy looking into what you are proposing; until I can, I wanted to throw another option to you just because of the general look of it (there are so many out there, that is part of the joy). I have a "Sherwood Frost" arborvitae that is very slow growing, and tops out at about ten feet. It is a wider pyramidal shape, but is definitely NOT deer-proof. Perhaps part of what you like about the aesthetics of the chamy obtusa is the architectural way that their fronds splay and twist a bit. It is definitely suited as a specimen focal point. I actually believe mine failed because I had them in very sandy soil. They became thinned out with interior browning instead of the full look that I was going for (as a hedge). However, few chamaecyparis will take soil that is too moist. I did have one in the blueish family that actually liked a wet soil (will have to look back to see what sub-species it was). If you continue to look hard enough, you will find what you want! http://woodyplants.nres.uiuc.edu/plant/thuocsf
