Black Locust circa 1920
Robinia pseudoacacia
Established in much of southern Ontario, the black locust is native to the eastern United States. Able to withstand a variety of stressful conditions, the tree is often chosen for restoration programs. It is planted in wasteland areas or abandoned mine dwellings where other trees are unable to sustain the infertile environment. Fragrant white flowers cover the tree in drooping clusters during early summer. Pursued by small animals and birds, the fruit remain attached to the tree throughout the winter.
