Trees, Shrubs and Woody Vines
American bladdernut is a thicket-forming shrub or small tree that grows in moist soils. It produces clusters of bell-shaped white flowers in spring and unusual 3-parted air-filled capsules in late summer that turn papery and persist into winter.
About Trees, Shrubs and Woody Vines in Missouri
There are no sharp dividing lines between trees, shrubs, and woody vines, or even between woody and nonwoody plants. “Wood” is a type of tissue made of cellulose and lignin that many plants develop as they mature — whether they are “woody” or not. Trees are woody plants over 13 feet tall with a single trunk. Shrubs are less than 13 feet tall, with multiple stems. Vines require support or else sprawl over the ground.
