Prunus myrtifolia, when compared with P. caroliniana, has flowers more widely spaced on longer rachises and pedicels, and flowers in the winter rather than the spring. The leaves of P. myrtifolia are broader on average, and their apices are blunt at the tip; the fruits are more rounded at the apices with smaller apicula.
