Wikipedia Abstract

Robinia pseudoacacia, commonly known in its native territory as black locust, is a medium-sized deciduous tree native to the southeastern United States, but it 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. Another common name is false acacia, a literal translation of the specific name (pseudo meaning fake or false and acacia referring to the genus of plants with the same name.) It was introduced into Britain in 1636.

Usage [4]  A drying oil is obtained from the seed; An essential oil is obtained from the flowers. Highly valued, it is used in perfumery; A yellow dye is obtained from the bark; Robinetin is a strong dyestuff yielding with different mordants different shades similar to those obtained with fisetin, quercetin, and myricetin; with aluminum mordant, it dyes cotton to a brown-orange shade; The bark contains tannin, but not in sufficient quantity for utilization; On a 10% moisture basis, the bark contains 7.2% tannin and the heartwood of young trees 5.7%; The bark is used to make paper and is a substitute for silk and wool; Trees sucker freely, especially if coppiced, and they can be used for stabilizing banks etc; Wood - close-grained, exceedingly hard, heavy, very strong, resists shock and is very durable in contact with the soil. It weighs 45lb per cubic foot and is used in shipbuilding and for making fence posts, treenails, floors etc; A very good fuel; The wood of Robinia pseudoacacia var. rectissima, the so called 'Long Island' or 'Shipmast' locust, has a greater resistance to decay and wood borers, outlasting other locust posts and stakes by 50 - 100%;
