Varieties: D. mosieri (Small); D. virginiana var. platycarpa Sargent; D. virginiana var. pubescens (Pursh) Nuttall; D. virginiana var. virginaiana[2]

The genus name Diospyros derives from the Greek name meaning fruit of the god Zeus.[3]

Description

D. virginiana is a perennial tree of the Ebenaceae family native to North America.[1] Its common name, persimmon, is of Algonquian origin.[3] The tree can reach heights of 5 to 21 meters tall, with mature bark that is thick, blocky, and dark grey in color. Leaves simple, deciduous, alternately arranged, ovate to elliptic or oblong in shape, and entire with an acuminate apex as well as a rounded base. The underside of the leaves are usually lighter-colored, more often on younger leaves. The leaves can change color to a yellow or reddish-purple in the fall. Flowers staminate or pistillate borne on separate trees located on the shoots of the current year's growth. Pistillate flowers are short-stalked or sessile, bell-shaped, fragrant, corolla greenish-yellow to creamy, and 4 lobes. Staminate flowers are borne in clusters of 2 to 3 flowers, tubularly shaped, and greenish-yellow in color. Fruit is a greenish-yellow berry that contains a highly astringent pulp before ripe, and turns a yellow-orange color when ripe with 1 to 8 flat seeds inside.[4] East from the Mississippi River, D. virginiana has cuneate to rounded leaves at the base that are glabrous or glabrescent, while D. virginiana west of the Mississippi River have subcordate leaves that are persistently pubescent. These differences could be worthy of varietal recognition.[5]

Distribution

D. virginiana is found throughout the east coast and southeastern United States as well as California and Nevada. [1] While it is sparingly in other areas, its dominant distribution is in the east-central and southeastern United States.[4]

Ecology

Habitat

D. virginiana is easily adaptable to a wide range of soils and climates; it prefers moist and well-drained soils, but can also tolerate dry, hot, and poor soils. Habitats include from dry, sterile, and sandy woodlands to rocky hillsides and river bottoms. However, best growth is usually on clay and heavy loam soil on terraces of large streams and river bottoms. In the Mississippi Delta, it grows on shallow sloughs, wet flats, and swamp margins. It is shade tolerant, but grows best in full sun. In disturbed sites, it is usually an early pioneer species, and can commonly be found along fencerows and roadsides. It can also be found to grow in thickets in pastures and open fields.[4] All soils it can grow on include sandy and sandy loam, medium loam, clay loam and clay, acid-based, and calcareous.[3] D. virginiana is considered one of the most common mid-story vegetation in the upper panhandle savanna and clayhill longleaf woodlands in Florida. [6] As well, a variety of habitats have been visited for samples of D. virginiana including mixed woodlands, pine wiregrass community, lowland woodlands, old field, dry sandy soils, edge of branch swamp, and sandy ridge near swamp. [7] It also grows in pine-oak-hickory forests.[8] While it can be commonly found in upland habitats, it prefers lowland habitats.[9]

D. virginiana has shown positive regrowth in reestablished longleaf pinelands that were disturbed by agriculture-based soil disturbance in South Carolina's coastal plains, making it an indicator species for post-agricultural woodlands.[10] However, it was found to not respond to soil disturbance by agriculture in North Carolina or to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[11][12] D. virginiana was found to increase in frequency and density in response to soil disturbance by roller chopping in northwest Florida sandhills. It has also shown regrowth in reestablished native sandhill habitats that were disturbed by this practice.[13]

Associated species: Quercus laevis, Quercus chapmannii, Quercus virginiana, Quercus geminata, Pinus palustris, Pinus elliottii var. densa, Aristida sp., Ximenia americana, Cyrilla parviflora, Nyssa sylvatica, Magnolia sp., and others.[7]

Diospyros virginiana is frequent and abundant in the Clayhill Longleaf Woodlands and Upper Panhandle Savannas community types as described in Carr et al. (2010).[14]

Phenology

General flowering time of D. virginiana is from May to June with fruiting occurring between September and December and persisting.[5] It has been observed flowering in April and May as well.[15] Preferred fruit-bearing age is between 25 to 50 years, even though fruit can start producing on 10 year old years.[4]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates.[16] These include being eaten by various birds as well as by various mammals.[17] One study found it to disperse great distances over a wide range of elevations.[17]

Seed bank and germination

D. virginiana can germinate easily from stratified seeds, even though scarification does not seem to improve germination rates. However, clipping the caps can bring more successful germination rates by encouraging radicle emergence instead. Seeds should be stratified in moist peat for 30 to 60 days at 36 to 41 degrees.[3]

Fire ecology

Populations of Diospyros virginiana have been known to persist through repeated annual burns.[18][19] It is a common species in many fire-disturbed habitats.[20] D. virginiana has been shown to increase in frequency in response to fire disturbance, where one study found it to increase by 63%.[21] Another study found this species to have highest density in burned bluestem (Andropogon sp.) dominant habitats in northwest Florida.[22] Prescribed burns can be used to control the species, but fire exclusion can decrease its likelihood of surviving. As well, the roots and rootstocks of the plant can be killed with severe fires that char the soil, but less severe fires only top-kill the plant. When top-killed by fire or even cutting/pruning, vigorous sprouts produce from the root collar.[4] A study on fire exclusion found the number of trees to increase over time since fire disturbance, but for basal area to decrease.[23] It seems to benefit from 3 year and 6 year burn cycles.[24] One study by Schafer and Just conducted coppicing of multi-stemmed trees, including D. virginiana, to find how they are affected by disturbances like fire. They found this species to not be positively correlated with the pre-coppicing number of stems to number of resprouts, and speculated that factors like proximity of buds to the soil surface, bud activation, and pre-fire stem size could have affected the number of resprouts.[25]

Pollination

This plant is dioecious, meaning that male and female plants are separate individuals.[5] It is commonly pollinated by various native bees, and is of significant importance to these pollinators.[4][3]

Herbivory and toxicology

Flies of the families Syrphidae and Tachinidae (Diptera) have been collected from D. virginiana and is identified as a floral host.[26] More specifically this species has been observed to host assassin bugs such as Zelus luridus (family Reduviidae) and ground-nesting bees from the family Andrenidae such as Perdita bradleyi and P. townesi.[27]

This species consists of approximately 50-10% of the diet for large mammals, small mammals, and various terrestrial birds.[28] Bees use the nectar from the flowers for honey. White-tailed deer eat the twigs and leaves as well as the sprouts after fire or other disturbances. The fruit of the tree is eaten by squirrel, fox, skunk, deer, bear, coyote, racoon, opossum, quail, wild turkey, catbird, cedar waxwing and other various birds. Various natural defoliators of D. virginiana include the webworm (Seiarctica echo) and the hickory horned devil (Citheronia regalis).[4] The fruit has low pulp quality for birds.[29] It is also seldom eaten by gopher tortoises (Gopherus polyphemus).[30] This species is also an adult food source for the Luna moth (Actia luna).[3]

Diseases and parasites

D. virginiana can be susceptible to a wilt fungus (Cephalosporium diospyri) that kills many of these trees in the southeastern United States. Individuals can become infected through small branches being severed by a twig girdler (Oncideres cingulata), where these wounds leave the plant vulnerable to infection of the wilt fungus.[4] It is also a host plant of the false spider mite Brevipalpus phoenicis.[31]

Conservation, cultivation, and restoration

D. virginiana is listed as a species for special concern by the Connecticut Department of Environmental Protection, and it is listed as endangered by the New York Department of Environmental Conservation, Division of Land and Forests.[1] It is an important species to conserve for it being one of the species that is fruit-bearing on sandhills that many species utilize.[32] This species, however, can be undesirable for growers of closely managed timber stands. For management, it can be mainly controlled by prescribed burns as well as various herbicides.[4] It is tolerant of the herbicides Dicamba, Hexazinone, and Triclopyr, and is susceptible to the herbicide Imazapyr.[33] A study found that managing areas for red cockaded woodpeckers brought an increase in frequency of D. virginiana.[34]

D. virginiana is a good species to utilize for erosion control due to its deep taproot. Various cultivars of this species are available, which were selected primarily for differentiating fruit taste, color, size, maturation time, and seedless cultivars.[4]

Cultural use

It is an edible fruit for humans as well, known for being sweet yet can be bitter if the fruit is not fully ripe.[5] The fruit can be used to make cookies, puddings, custard, cakes, and sherbet, and the seeds can be dried, roasted, and ground to make a substitute for coffee. The wood can be used for textile shuttles and heads for driver golf clubs due to it being smooth, hard, and even textured. The inner bark and unripe fruit can be used medicinally to treat fevers, diarrhea, and hemorrhage.[4] Native American tribes also used the species to make persimmon bread, and dried the fruit for storage. This fruit was the most prized by Native Americans in the southeastern United States.[3] The bark is an astringent, febrifuge, and anti-periodic, while the fruit is an astringent as well.[35] This species can also be diffused to make domestic liquors.[36]
