Green Deane is great, I love his videos. As far as Vaccinium Arboreum aka Farkleberries goes they are edible but are best used in preserves or jams because they tend to be very acidic. Green Deane is based out of FL and Farkleberries are a TX native so chances are he don't and won't have a vid on them but if you want to learn more about them you can google Vaccinium Arboreum and they also go by the name Sparkleberry if that helps.
Speaking of wild edibles of TX have you ever seen Diospyros Texana aka black persimmons in your area? I'd like to cross D.Texana with a large fruiting Diospyros Virginiana someday. I love the thought of interspecific hybrids and would love to see more work done with them.
