The Black Cherry, also known as wild black cherry, rum cherry, or mountain black cherry (Prunus serotina), is a deciduous tree or shrub in the rose family (Rosaceae). Unlike commonly cultivated cherries like sweet cherry or sour cherry, it belongs to a different subgenus (Padus), making it more closely related to the chokecherry and Eurasian bird cherry. Native to North and South America, it is widespread and commonly found in forests, old fields, and along forest margins. Identification Features: Black Cherry trees are medium-sized and fast-growing, typically reaching heights of 49–79 feet. The leaves are 2–5 inches long, ovate-lanceolate, with finely toothed edges and a shiny surface, resembling those of a sourwood. In fall, the leaves turn yellow to red. The bark of young trees is thin and smooth, but matures to a dark gray or black with a broken, rough texture. When a twig is scratched, it releases an almond-like odor due to cyanide compounds, a natural defense against herbivores. The flowers are small, white, and arranged in racemes that are 4–6 inches long. These flowers develop into reddish-black drupes ("berries") that are 1/4 to 3/8 inch in diameter, which are readily eaten and dispersed by birds. Toxicity and Ecological Role: Black Cherry contains cyanogenic glycosides in its seeds, foliage, and bark, which release hydrogen cyanide when crushed or wilted, posing a risk to livestock and other animals. Farmers often remove fallen trees or branches from grazing fields to prevent poisoning. Despite its toxicity, the tree plays an essential role in the ecosystem, serving as a host for various caterpillars and providing food for birds and mammals. Growth and Uses: As a pioneer species, Black Cherry is found in old fields and roadsides, often alongside other sun-loving trees like black walnut and hackberry. It is a long-lived tree, sometimes reaching up to 258 years of age, and starts producing fruit around 10 years, with heavy production continuing for decades. The wood of the Black Cherry is highly valued for cabinetry and furniture, known for its rich orange hues and tight grain. It has also been introduced to Europe as an ornamental tree, where it has become invasive in some areas, impacting local biodiversity.
