What are the differences among bitternut, bladdernut, and butternut?
These are the common names of three different species of woody plants. Bitternut, Carya cordiformis, is a hickory whose fruit is a bitter nut that even squirrels ignore. Bladdernut, Staphylea trifolia, is a large shrub that bears an inflated capsule containing several inedible hard, yellowish-brown seeds. Butternut, Juglans cinerea, is a large tree that bears sweet, edible nuts.
