Howdy folks,
In regards to this message:

James
www.treefolks.com has a list of trees that are suitable, with a chart
to compare size and other characteristics. Yaupon holly is one
year-round green shrub/tree that springs to mind. Wax myrtle is also
recomended, but I don't know if it drops its leaves over winter or
not.

My impression was that Treefolks was closing it's doors due to loss
of funding. ( I hope I'm wrong )
The city of Austin Grow Green program has a plant guide that is good
and lists small trees for Travis county. Check them out at:

take care,
