Malus ioensis
Once commonly found in the prairies and savannas in the Midwest, Prairie Crabapple is one of three crabapple trees native to North America. Showy spring blooms, that are popular among pollinators, give way to small, yellow-green fruits that are fed on by a range of birds and mammals. Being densely branched, Prairie Crabapple provides good nesting habitat for birds, and its tendency towards making thickets provides good cover for many mammals. The fruits, while edible, are very sour and bitter and best consumed cooked.
