Chinese Evergreen Oak - Quercus myrsinifolia do well, here in the Tennessee Valley, zone 7. They can get as large as 40 feet or so but most of the few that I have seen are about 20' to 25'. It is truly evergreen and a relatively rare tree around these parts. In Michael A. Dirr's book, "Manual of Woody Landscape Plants", there is mention of sapsuckers wreaking havoc on this species in some areas and the fact that this could be a limiting factor in the use of this tree. The mature trees that I have found locally show no sign of sapsucker damage. Perhaps the TN Valley is inhabited with more refined, well mannered sapsuckers or could be their peckers don't work. Aside from sapsuckers and a brief mention of canker in Dirr's text, this species appears pest and disease free. I am growing a small number of them in containers. Locally, in the Tennessee Valley, I have only seen 3 mature specimens. One in Cullman, AL that is about 20' x 20'. A beauty. Another in Athens, AL that looks a lot like the Cullman tree and a huge specimen in Huntsville, AL that has got to be about 35 - 40 feet tall and 30-35 feet wide. Other evergreen oaks, if you can find them, are the Japanese Evergreen Oak, the Blue Japanese Oak, the Ubame Oak and Quercus salicina. All might be difficult to obtain but mysinifolia can be found in the Southeast. Attached are photos of the one tree that I know of in Cullman, AL.. Photos made 6-23-04. The story that I was told by a local nurseryman is that the lady who lives there bought it down along the gulf coast, South Alabama, as a Live Oak. I have also heard from a gentleman in Huntsville, AL, that many years ago a traveling tree salesman was selling these trees in that area.
