[7] Chickasaw plum grows 3.7 to 6.1 meters (12 to 20 feet) tall and 4.6 to 6.1 m (15 to 20 ft) wide in an irregular shape.

In February, March, April and May, small white flowers blossom, 8–10 millimeters (5⁄16–3⁄8 inch) wide, along with red plums, up to 25 mm (1 in) long.

It requires low to medium amounts of water to grow, and dry, sandy or loose soil.

[citation needed] P. angustifolia is very difficult to distinguish from P. umbellata, with which it hybridizes easily.

[10] P. angustifolia is widespread across much of the eastern and central United States from Florida west as far as New Mexico and California, north to Nebraska, Illinois, and New Jersey, with a few isolated populations in northern Michigan.

[13] Because of its attractive bark, small leaves and thin branches, Chickasaw plum is also sometimes used for bonsai.
