Nutgall tree, also known as Chinese sumac, is the tallest representative of the cashew family that will grow in the Midwest. It is a suckering shrub with an open habit that will reach 20 feet in height, with irregular spreading branches. The attractive leaves are compound, with a winged petiole. These large shrubs, located south of our picnic area, are unnoticed until September, when huge panicles of tiny creamy-white flowers appear. These attract pollinators, however, fruit is not produced without a male plant nearby.
