Mexican Plum - Prunus mexicana
With an extended range from the Midwest to southern Texas and Mexico, this is a small plum that occupies habitats varying from rich woodlands and bottomlands to rocky hillsides. It is most easily distinguised by its hairy flower stalks, leaf stalks, and flowers. The crown is open and irregular, the trunk straight, and the very dark bark furrowed on old trees. The leaves have a long tip, are rounded, double-toothed, and sometimes have glands. They are shiny above and hairy along the veins below. The flowers are in small clusters and are white and rounded; the fruit is purple with a thick flesh.
