Crabapples are versatile, small, ornamental trees used in the urban landscape. Crabapples bloom in spring, usually in May, bearing flowers that vary a great deal in color, size, fragrance, and visual appeal. It is common for flower buds to be red, opening to pink or white flowers. The fruit ripens between July and November, and varies in size from ¼”to 2” long or wide. Crabapples thrive in full sun and grow best in well drained, slightly acidic soils (pH 5.5-6.5); however, they will grow well in many soil types. Most crabapple selections tolerate the cold winters and hot, dry summers prevalent in the Midwest.
 
The fruits have a bitter taste. The leaves are dark green above and paler underneath, turning brown in the fall. The bark on crab apples is typically gray or brown furrowed into narrow scaly ridges, sometimes having a peeling appearance. 
Where it Grows:
Crab apple cultivars can grow in a variety of different site conditions such as valleys and lower slopes, borders of forests, fence rows, fields, and along streams in prairies. The main preference for all cultivars is that it needs moist, well-drained slightly acidic soils. They thrive in full sun.
How it's Used:
Crabapples are widely used under power lines as boulevard trees as well as landscape trees. Some cultivars' wood is used for tool handles. Preserves and cider can be made from the fruit. 
Ecosystem Services:
The fruit is a food source for a white variety of songbirds, migratory birds, and small mammals from squirrels to foxes.
