Dolgo aka Dalgo crab apple serves well as an ornamental and edible fruit producing tree. It is fairly large as crab apple trees go reaching over 30 feet in height at times. Good resistance to scab and fire-blight. It is frequently paired with other fruits in preserves and sauces.

Spring Flowers are rosy pink and appear earlier than most varieties. Purplish red fruit is ripe by early September into October. The foliage is perhaps the reason this cultivar is so popular in the spring it has Leaves have a purple tinge that offsets the rosy pink blooms. The fruit is very small, sometimes berry sized and will hang on the tree into midwinter if left unharvested. Edible fresh or for preserving.
7. Prairie Fire is another relatively new variety that can reach up to 20 feet in height but averages around 12 -15. It's foliage is strikingly maroon to dark lavender, come Autumn it morphs to variant shades of auburn, orange and red.

It is also suitable for the deep south, in essence it is a very adaptable and versatile tree. Produces attractive white flowers prolifically in the spring which give way to clusters of sweet crab apples. This hybrid does not have the acidity or tartness associated with most crab apples. The only drawback I noticed so far as taste is concerned is that they are not as crisp as you would expect with a fresh apple. In fact once they hit tehir peak they degrade quickly, so harvesting just before they ripen fully is best in my opinion.
