Robinia pseudoacacia, commonly known in its native territory as black locust,[1] 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[2] 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.
Description
Black locust reaches a typical height of 40–100 feet (12–30 m) with a diameter of 2–4 feet (0.61–1.22 m).[3] Exceptionally, it may grow up to 52 metres (171 ft) tall and 1.6 metres (5.2 ft) diameter in very old trees. It is a very upright tree with a straight trunk and narrow crown which grows scraggly with age. The dark blue-green compound leaves with a contrasting lighter underside give this tree a beautiful appearance in the wind and contribute to its grace.
Black locust is a shade intolerant species[4] and therefore is typical of young woodlands disturbed areas where sunlight is plentiful and soil is dry, in this sense, black locust can often grow as a weed tree. It also often spreads by underground shoots or suckers which contribute to the weedy character of this species. Young trees are often spiny, however, mature trees often lack spines. In the early summer black locust flowers; the flowers are large and appear in large, intensely fragrant (reminiscent of orange blossoms), clusters. The leaflets fold together in wet weather and at night (nyctinasty) as some change of position at night is a habit of the entire leguminous family.
Uses
- In traditional medicine of India, different parts of R. pseudoacacia are used as laxative, antispasmodic, and diuretic.[5]
- In Romania the flowers are sometimes used to produce a sweet and perfumed jam. This means manual harvesting of flowers, eliminating the seeds and boiling the petals with sugar, in certain proportions, to obtain a light sweet and delicate perfume jam.
- In France and in Italy, R. pseudoacacia flowers are eaten as beignets after being coated in batter and fried in oil; they are also eaten in Japan, largely as tempura.
- It is very resistant to rot, and durable, making it prized for furniture, flooring, paneling, fence posts, and small watercraft.
