Taxonomic Notes

Synonyms: Prunus serotina ssp. serotina[1]

Varieties: Prunus serotina Ehrhart var. serotina; Prunus serotina Ehrhart var. eximia (Little) Small[1]

Description

P. serotina is a perennial shrub/tree of the Rosaceae family native to North America and Canada.[2]

Distribution

P. serotina is found in the eastern half of the United States excluding South Dakota, as well as the British Columbia, Ontario, and Quebec regions of Canada.[2]

Ecology

Habitat

P. serotina proliferates in rich coves, bottomlands, northern hardwood forests, and in a wide variety of lower elevation habitats from dry to mesic, and weedy in fencerows.[3] Specimens have been collected from habitats that include wet woods, sandpine woods, longleaf pine wiregrass scrub oak stand, dense swampy forest, open woodland, mesic mixed hardwoods, dry long leaf pine sandhills, hammock, thin stand of planted slash pine, dry mesic harwood forests, slope of narrow ravine, river bank, and semi shaded moist loamy sand in open woodland.[4]

P. serotina has shown regrowth in reestablished longleaf woodlands in South Carolina coastal plains communities, making it a post-agricultural woodland indicator species.[5] It exhibits no response to soil disturbance by improvement logging in Mississippi.[6]

Prunus serotina is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[7]

Phenology

P. serotina has been observed to flower February through April.[8] This tree sometimes reaches a height of 90 feet and a maximum trunk diameter of 4 feet. The trunk is straight and covered with rough black bark, but the young branches are smooth and reddish. The smooth shining leaves are about 2 to 5 inches long. The long drooping clusters of small white flowers are borne at the ends of the branches, usually during May. The cherries, which ripen about August or September, are round, black, or very dark purple, about the size of a pea, and have a sweet, slightly astringent taste.[9]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates.[10]

Fire ecology

Populations of Prunus serotina have been known to persist through repeated annual burns.[11][12][13]

Herbivory and toxicology

Prunus serotina has been observed to host spittle bugs such as Clastoptera proteus (family Clastopteridae), ground bees from the Andrenidae family such as Andrena crataegi, A. forbesii, A. neonana, and Perdita bradley, aphids from the Aphididae family such as Aphis sp. and Myzus sp., leafhoppers from the Cicadellidae family such as Eratoneura ardens, Erythroneura comes, E. elegans, E. tricincta and Graphocephala coccinea, sweat bees such as Lasioglossum cinctipes (family Halictidae), treehoppers from the Membracidae family such as Entylia carinata, Micrutalis calva, and Telamona monticola, plant bugs such as Psallus variabilis (family Miridae), moths such as Furcula borealis (family Notodontidae), and true bugs such as Zelus luridus (family Reduviidae).[14] P. serotina is a bird-dispersed species.[15] It also serves as the main host plant for the eastern tent caterpillar.[16] This species is a larval host for tiger swallowtail, mourning cloak, and white admiral butterflies.[17]

Diseases and parasites

P. serotina is susceptible to the black knot fungus.[16] The parasitic species Phoradendron leucarpum or American Mistletoe has been observed on the P. serotina branches.[17]

Conservation, cultivation, and restoration

Cultural use

A bark tea was used in Appalachia to treat coughs, colds, measles, and relieve pain and muscle soreness, treat fever, intestinal worms, indigestion, and tuberculosis. The berries were used in teas to treat diarrhea.[18]

The fruit was used in jellies or eaten fresh.[19]
