Robinia pseudo-acacia /Pea Family
April 24, 2005
Black Locust is in the Pea Family. These trees make a beautiful showing in Roane County along Interstate 40 in early May. Black Locust has small thorns and short (6"-8") pods; Honey Locust has long, wicked thorns and long (8"-18") seed pods. I remember the difference between the two trees by thinking that bees make honey and they have wicked stingers! Black Locust contains poisons in the seeds, bark and leaves, it is poisonous to sheep, horses, cattle, goats, poultry, and people if eaten.
