Malus ioensis, or the prairie crabapple, is a species of crabapple tree native to the United States. The most common variety, Malus ioensis var. ioensis, is found primarily in the prairie regions of the upper Mississippi Valley. Another variety, Malus ioensis var. texana, or the Texas crabapple, is found only in a small region of central Texas.
The prairie crabapple tree can grow up to 35 feet (10 m) in height. It bears white or pink flowers in the summer and small apple-like berries in the fall.
