Many Crabapple trees can be found wild in our area. The crabapple is actually the only "native" apple tree in North America. Most crabapple trees in our region bear green fruits, like the one pictured here. They can be wormy but they do have an excellent tart flavor and crispness similar to the Granny Smith.
Often found in Suburbia for it decorative traits, this fruit can be useful to foragers, homesteaders, and locavores (those who try to eat a local diet.)
