No matter where you drive in southern Indiana or central Kentucky, the black locust, Robinia pseudoacacia, is in full bloom, and a glorious bloom it is. There is nothing like the fragrance of black locust blooms wafting in the air and the Orchard Oriole singing in the trees, or so my wife, Carole, says. I have to admit the blooms smell awesome. Although the tree is not much to look at otherwise, I believe it rivals the beauty of the common dogwood when it is in bloom. Its blooms are also a good source of nectar for honey bees.
