The storied agarita berry plant of the Texas Hills has a small, yellowish berry that is highly favored by many but, alas, the time required to pick a gallon of these berries kinda takes the shine off the finished product. Although not native, blueberries are now being grown in Texas. They grow very large but to me, they are lacking in taste. We can't finish here without mentioning honey. Honey is nature's sweet gift from the honeybee.
Nothing is as good as a good helping of clover honey on a buttered biscuit.
We are going to have to start taking care of our honeybees, though, because they pollinate nearly every fruit and vegetable on our tables. Without them, we'll be on an all meat diet. Jams, jellies and their ilk go best with fresh butter. My favorite was always plum jelly. In those days, every garden had a plum tree or two.
