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.[1] [2]
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.
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.[3] They are eaten by various wildlife.[4]
Because of its relative hardiness in comparison to other Vaccinium species, Vaccinium arboreum has been investigated as a potential rootstock for expanding the range of blueberry cultivation to less acidic soils(PH>6.0) and reducing the severity of bacterial leaf scorch[5] Cytology is 2n = 24.[6]
