Chickasaw Plum - Prunus angustifolia
Distinguished by leaves that tend to fold upward along the midvein, this is a southern plum that prefers open habitats, such as alongside fields, stream banks, and in sand dunes. Widely naturalized in the Southeast, it is a small tree with a narrow trunk, and tends to form thickets. The reddish-brown bark is marked the horizontal bands; young branches are bright red. The leaves are lance-shaped and pointed at the tip. This plum has small, thorn-like branches. The flowers have a lobed calyx and 5 white petals; the half-inch fruits are red to yellow and somewhat acidic.
