Select These Ornamental Crabapples

For those gardeners tired of Bradford pear problems, go shopping for ornamental crabapples (Malus spp.). Selected cultivars mature into lovely small spring flowering trees. Most fit under utility lines. Be careful which cultivars you choose.

Worldwide, there are over 400 cultivars of crabapples in nursery commerce. Most are susceptibility to one or more serious foliar diseases that include fire blight, cedar apple rust, apple scab, powdery mildew and frog-eye.  All 19 listed below are rated with above average disease resistance.

Ornamental crabapple fruits add ornamental beauty in fall and winter seasons. Fruit size is small, less than 5/8 inches in diameter. An extra bonus is that small birds are attracted to the fruits from late fall thru winter.  There is no mess on lawns, walkways or cars.

Consult experts at your state's land grant university for an updated listing which may also additional cultivars. Varieties 'Prairifire', 'Sugartyme', Japanese flowering crabapple (M. floribunda) and M. x sargentii are popular at garden centers nationwide.
