I don't often get a chance to eat many Farkleberries, the birds love them and know exactly when they're ripe for picking. I will say that once ripe, they're quite sweet and tasty. Last winter my grandson ran across some shriveled up berries and asked if they were edible. I told him yes and we discovered they were sweet like raisins, I would even say delicious!
Yes, Diospyros Texana grows wild here. I still haven't found the fruits but I know they're around here somewhere because many times I've run across coon scat with seeds. I think we still have several small trees growing from those seeds.
