Malus, apple, is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple [Malus domestica]. The other species are generally known as crabapples, crab apples, crabs, or wild apples.
Crabapples are small to medium-sized, deciduous trees that are widely adapted and produce an abundance of flowers in spring. There are more than 500 varieties.
Crabapples bloom in early to mid-spring, producing masses of pink, red, or white flowers, depending on the variety. Some also have attractive purplish red leaves. Many types also produce small, red or yellow edible fruits that are tart but excellent for jelly. Most crabapples grow 15 to 25 feet tall and wide at maturity. Some weeping and dwarf forms grow less than 10 feet tall. The fruit remains on the branches into fall, providing food for wildlife, and the branch structures on many varieties provide interesting forms in winter.
