Description:

Robinia pseudoacacia, commonly known as the Black Locust, is a tree in the subfamily Faboideae of the pea family Fabaceae. It is native to the southeastern United States, but has been widely planted and naturalized elsewhere in temperate North America, Europe, Southern Africa and Asia and is considered an invasive species in some areas. A less frequently used common name is False Acacia, which is a literal translation of the specific epithet. It was introduced into Britain in 1636.

With a trunk up to 0.8 m diameter (exceptionally up to 52 m tall and 1.6 m diameter in very old trees), with thick, deeply furrowed blackish bark. The leaves are 10-25 cm long, pinnate with 9-19 oval leaflets, 2-5 cm long and 1.5-3 cm broad. Each leaf usually has a pair of short thorns at the base, 1-2 mm long or absent on adult crown shoots, up to 2 cm long on vigorous young plants. The intensely fragrant (reminiscent of orange blossoms) flowers are white, borne in pendulous racemes 8-20 cm long, and are considered edible (dipped in batter; deep-fried). The fruit is a legume 5-10 cm long, containing 4-10 seeds.
