  • Evergreen? Southern Live oaks are known as evergreen oaks, since they retain their leaves into winter.  However, some consider them not to be true evergreens. [Technically (Flora of North Amer.), subevergreen. Because typically in early spring as temperatures rise slightly, all the old leaves begin to yellow, senesce, and drop over a period of several weeks, these changes coincide with the emergence of new leaves. It can be successfully grown in Western Oregon, the old leaves may drop in especially cold winters, with the tree leafing out again in spring.

  • There about 21 Quercus species in the US that are designated as live oaks.  Most are in the southeastern and southwestern states as well as Texas and California (Wikipedia)
