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.
This plant is present in at least 16 states/provinces in this country.
A miniature apple tree in most respects, prairie crabapple grows to 35 ft. with a dense, irregular form. A sometimes spiny shrub or small tree, with spreading branches and broad, open crown. Exfoliating bark reveals silvery-gray inner bark. The large, white or pink, flowers grow in clusters that cover the tree. A yellow-green, apple-like berry is not ornamental by crabapple standards. If the foliage has escaped premature defoliation from fungus disease, it can develop a deep crimson color in fall.
This is the crabapple of the eastern prairie region in the upper Mississippi Valley. A handsome double-flowered variety is grown as an ornamental.
