These trees are best adapted to our climate and water availability.
These trees require frequent summer irrigation, and will suffer from the drought cycle in our area. Do not plant unless you are aware of a water source such as high water table or creek proximity.
These trees are either invasive, do not perform well, or create infrastructure or other problems.
