Discussion

Prunus caroliniana is a popular ornamental for screens and trimmed hedges and is widely planted in the southeastern United States because of its lustrous, dark green foliage persistent through the seasons. The species was probably common as a native plant on the southeastern barrier islands; most inland occurrences represent escapes from cultivation. It rarely escapes from cultivation in California.
