Photo at left shows the mother tree of ‘Cathedral’ Southern Live Oak, with it’s excellent upright growth habit.
At left, ‘Cathedral’ oak in late fall planted as a street tree in Dallas, TX. At right is another young ‘Cathedral’, this time in East Palo Alto, CA.
At right is the glossy green foliage of ‘Cathedral’. Below is a very nice seedling (non-cultivar) Southern Live Oak in Santa Barbara as a street tree.
Southern Live Oak is a semi-evergreen temperature, losing some of it’s leaves in the winter, but not all. Amount of leaf lost depends on minimum temperatures for that winter.
Above, comparison of Southern Live Oak, at right, and Coast Live Oak (Quercus agrifolia) in San Jose.
