I am ignorant about where your zone is (lack of knowledge). A specimen of a
tree biology workshop was a Gamble Oak. It thrives in the Desert near Salt
Lake City, Utah. You don't see a gamble oak you see gamble oaks. They
thrive in groups. I think they said they were a shorter tree. They are
ring porous and form tyloses in most vessels other than the current growth
increment. In other words, the sapwood, in a cross section reveals that the
tree has conducting and nonconducting sapwood. Sapwood, older than one
year, have their vessels plugged with tyloses. A balloon type structure.
The back cover on 100 TREE MYTHS by Dr. Shigo has a dissection picture.

Where is zone 12?

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

They are listed on google search site as a tree that grows to be only
20-30'. And is in zones 4-7.

Hi,
I live in a Sunset zone 12 (Intermediate Desert) and am looking to
plant some fast growing shade trees. Does anyone have any
suggestions? Thanks!
