Howdy from the Piney woods of East Texas....they don't call this the Piney woods for nothing.
I notice you show zone 8b and that happens to be my zone also.
The longleaf pine (Pinus palustris Miller) has properties than many folks have used for generations in these woods.
The pollen, a yellowish powdery substance works as a flour substitute and/or stew thickener...but is only available in spring. It accumulates on everything such as windshields overnight and is readily collected. The long needles for which it is named are often used to make tea...very tasty and I hear nutritious. The longleaf I have produces very large pinecones from which excellent pine nuts can be gathered. The inner bark is edible, I'm told, and nutritious (tender white meat between the outer bark and the inner trunk).
The mighty longleaf has a life expectancy of 300 years and grows to great heights...but is relatively slow growing. It has been harvested out of most of East Texas and is not generally replanted except as conservation measures because it isn't economical like the other soft pines like loblolly.
