Definition of false acacia in US English:

false acacia


  • A tree of the same family as the true acacias (Leguminosae), but of a different genus (Robinia), in particular the black locust of North America.

    • ‘Locust trees, or false acacias, also present imputrecible (rot-proof) characteristics and have the distinctive particularity to grow several shoots when they are cut to the stump, thus greatly facilitating their culture.’
    • ‘Beekeepers producing honey from the flowers of false acacias are panicking about the possibility that the trees may soon be regulated as an exotic species.’
    • ‘They both include a number of trees and mature shrubbery, including the protected false acacia.’
