Vaccinium arboreum (sparkleberry or farkleberry) is a species of Vaccinium native to the southeastern and south-central United States, from southern Virginia west to southeastern Nebraska, south to Florida, and eastern Texas, and north to Illinois.[rx][rx]
Vaccinium arboreum is a shrub (rarely a small tree) growing to 3–5 m (7.5-12.5 feet) rarely 9 m) (22.5 feet) tall, with a diameter at breast height of up to 35 cm (14 inches). The leaves are evergreen in the south of the range, but deciduous further north where winters are colder; they are oval-elliptic with an acute apex, 3–7 cm long and 2–4 cm broad, with a smooth or very finely toothed margin. Sparkleberry grows on sand dunes, hammocks, dry hillsides, meadows, and in rocky woods. It also grows on a variety of moist sites such as wet bottomlands and along creek banks.[rx]
The flowers are white, bell-shaped, and 3–4 mm (0.12-0.16 inches) in diameter with a five-lobed corolla, produced in racemes up to 5 cm (2 inches) long. The fruit is a round dry berry about 6 mm (0.24 inches) in diameter, green at first, black when ripe, edible but bitter and tough.[rx] They are eaten by various wildlife.[rx]

Vaccinium arboretum commonly known as Farkleberry is a large, much-branched tree belonging to Ericaceae (Heath family). Historically Farkleberries cousins include blueberry, bilberry, huckleberries, and more distantly cranberries. Other medicinal plants in this family include uva ursi and madrone. All of these plants tend to have astringency. The plant is native to central Florida westward to central Oklahoma, southeastern Missouri, southeastern Kansas, and the Edwards Plateau of Texas. It extends northward to southern Illinois, southern Indiana, and Virginia. Farkleberry, Sparkleberry, Winter huckleberry, Tree sparkleberry, Tree-huckleberry, tree whortleberry, winter whortleberry, and Missouri farkleberry are a few of the well-known common names of the plant. The plant is harvested from the wild for local use as food, medicine, and a source of materials. The tree usually flowers abundantly and is sometimes grown as ornamental.
The species name, arboretum, stems from the Latin root “arbor,” meaning “a tree,” because it is the only North American member of the Vaccinium genus that reaches a size comparable to that of a tree. The common name sparkleberry began to show up in the literature by 1891 and was given to the plant because of its rather shiny berries. The common name farkleberry is supposed to be a misinterpretation of the word sparkleberry.

Plant Description
Farkleberry is a large, stiff-branched, evergreen, or persistent-leaved, upright shrub or small tree that normally grows about 3–5 m (7.5-12.5 feet) tall, with a diameter at breast height of up to 35 cm (14 inches). However, on favorable sites, plants may grow to 33 feet (10 m) with a d.b.h. of up to 14 inches (35 cm). Record trees have been measured at 64 feet (19 m) in height with circumferences of up to 116 inches (45.9 cm). Farkleberry is the only member of the Vaccinium genus to reach tree size. The plant is found growing on sand dunes, hammocks, granitic outcrops, dry sterile hillsides, rocky woods, abandoned fields, meadows, wet bottomlands, along creek banks, coastal plain, in piedmont, moist sandy soils by ponds and streams, stream banks, bluffs, rocky ledges, rocky canyons, rocky ravines, rocky bluffs, sandstone glades, barren upland savannas, sand dunes, sandy savannas, pinelands, thickets, clearings, fields, coastal scrub forests and wooded streams. The plant prefers moist, acid, sandy, and well-drained soils.
Trunk
The trunk bark is brown, gray, or red, or some combination of these colors; it is thin and susceptible to shredding. Branches and older twigs are gray and relatively smooth, while young twigs are reddish-brown. Branches and twigs of this shrub are often bent. Young shoots are light green to reddish-green and usually pubescent, otherwise, they are glabrous. The wood is brown to reddish-brown, fine-grained, tough, and hard. Wood weighs an average of 48 pounds per cubic foot (112 kg/cu m). It was previously used to make various tool handles and craft items.
Leaves
Leaves are deciduous but can exhibit more evergreen characteristics in the warmer climates of its southern range. Leaves of farkleberry are variable in size, shape, and persistence. The simple, alternate leaves occur along with the young twigs and shoots. These leaves are 1-3 inches in length and ½-1½ inches across, and somewhat leathery in texture. They are ovate, obovate, or broadly elliptic in shape, while their margins are smooth (entire) or minutely serrated. The leaf tips are either rounded or taper abruptly to blunt points, while the leaf bases are usually wedge-shaped. Leaf venation is pinnate; the secondary veins are widely separated and relatively sparse across the leaf surface. The upper leaf surface is medium green, glabrous, and somewhat shiny, while the lower leaf surface is pale green and glabrous to finely pubescent (fine hairs are most likely to occur along the central veins of the leaves). The leaves often become red or purplish-red during the winter.

Flowers
The showy, white to pinkish flowers of farkleberry grow in abundance. The perfect flowers are borne in leafy-bracted racemes or panicles that average 0.8 to 2.7 inches (2-7 cm) in length. Inflorescences typically occur on second-year growth. The central stalks of these racemes are light green and finely pubescent, while the pedicels are about ½ inches long, light green, and glabrous. Each flower is about ¼ inches long and similarly across, consisting of a short calyx with 5 broad teeth. Bell-shaped corolla is nearly globoid in shape, 10 inserted stamens, and a pistol with a single style. The calyx is light green and glabrous, while the corolla is usually white (less often pinkish white). The corolla also has 5 small lobes along its outer rim that are recurved. In addition to the flowers, the racemes have leafy to scale-like bracts that are less than 1 inch in length. The blooming period occurs from July to August for about 3 weeks.

Fruits
Later, fertile flowers are replaced by lustrous, globoid berries about 0.2 to 0.4 inches (5-9 mm) in diameter at maturity during the late summer or fall. Fruits are initially green turning to black and shiny berries when ripe, often persisting into the winter. The interior of the berries is mealy and dry, varying in flavor from bitter to sweet. Each berry consists of 8- 10 seeds. The seeds are stony, shiny, and black to golden brown colored. The variously-shaped, deeply pitted seeds average 0.08 inches (2 mm) in length.
