Quercus agrifolia - Coast Live Oak 

I planted one in my back yard 35 years ago from a 6 inch seedling I pulled out of the ground up in the mountains of SoCal at 5000 ft elevation. We are at el. 650 ft. It is about 35 feet tall and about as broad. I suspect its shed leaves provide insulation that reduces ground water evaporation. It is evergreen. It regularly produces seedlings. I water it occasionally in the Summer. I love that tree.

Good info about how messy they are for so much of the year. Plant them where the mess will not be an issue.

california sisters use the tree as a host plant. Beautiful butterfly.

I want to try these in Louisiana but I don't think they would like the humidity. The temperatures would be similar to those you describe here.

How much do they grow each year
