Blueberry in Botany
Linnaeus grouped all plants into the plant kingdom Plantae, to separate them from animals. The blueberry is further classed with all plant producing flowers and seeds into the division Spermatophyta. The flower has an ovary, thus placing it in the class Angiospermae, and its seedling has two leaves, putting it in the subclass Dicotyledonae.
It is member of the Ericaceae family of plants comprising mostly woody shrubs that grow naturally on acid soils. This is a large family and is found widely distributed throughout the world. It includes, among others, the rhododendrons, azaleas, heathers, heaths, and mountain laurels.
The blueberry belongs to the subfamily Vacciniaceae; the tribe Vaccinieae; the genus Vaccinium; and the subgenus Cyanococcus (from Greek cyano (‘blue”) and coccus (berry).
There are many species. The terms “genus’ (pl. genera) and “species” are most commonly used when discussing plants horticulturally. The first letter of the genus name is always capitalized; the first letter of the species name is lower case. Both are italicized or underlined. Among growers, species are rarely mentioned, but a more specific term, “cultivar,” is common.
The highbush blueberry ranges from 5 – 23 ft in height. The cultivated highbush blueberry was developed primarily from two species: V. corymbosum L. and V. australe Small, though other species have been utilized in modern breeding programs. The letter, name or abbreviated name following the species refers to the person who first named it (e.g., “L” is the abbreviation for Linnaeus).
Wild plants are distributed in sunny, acidic and swampy areas from Nova Scotia and southern Quebec west to Wisconsin and south to northern Florida and southeastern Alabama. Wild southern populations are comprised primarily of V. australe Small, whereas V. corymbosum L. occurs in more northerly areas. Because of rampant hybridization, these species have intermingled and crossed with a half dozen other economically minor species, thus giving rose to various intermediate forms.
