Flowering Trees Master Gardener Core Training Gerald Klingaman and Janet Carson Cooperative Extension Service
Flowering trees Are accent points in the landscape plan Massed plantings give most impact Usually produce more blooms if given at least six hours of sunlight Being smaller plants, can be planted within five feet of the foundation of a home without concern
Flowering Dogwood Cornus florida Height 20 feet Spread 25 feet Growth rate - slow to medium Hardy zones 5 to 9 Moist but well drained soil Some afternoon shade or high understory best
Pink Flowering Dogwood
Avoiding Dogwood Problems Plant in the right location and water as needed Avoid stress to reduce the chance of borers Dont wound the trunk to avoid borers Put dogwoods where the foliage will dry early in the morning to avoid powdery mildew
Cornus kousa the Japanese Dogwood
Cornus kousa x C. florida Stellar Dogwood
Eastern Redbud Cercis canadensis Height - 25 feet Spread - 25 feet Growth rate - fast Hardy zones Best in full sun. Transplants best from container grown plants. Seed pods unsightly in winter Trunks can split in ice storms
Golden Raintree Koelreuteria paniculata Height - 35 feet Spread - 30 feet Growth rate - medium Hardy zones 5 -9 Best transplanted from container grown plants in spring. Very drought tolerant.
Bradford Pear Pyrus calleryana Height - 40 feet Spread - 35 feet Growth rate - fast Hardy zones Very formal in appearance with many branches creating weak trees. Multiple seasons of beauty but overplanted.
Problems with Bradford Pear Formal shape limits their use to formal landscape settings Larger than most people realize Break because of limb structure - prune up and thin out excess limbs Fruiting can result in escaped seedlings Select more narrow clones to avoid problems with the broad-spreading crown getting too large.
Buying Time by Severe Pruning One year after severe pruning
Capitol Flowering Pear
Fastigiate European Hornbeam Carpinus betulus Height - 45 feet Spread - 15 feet Growth rate - slow Hardy zones Good substitute for Bradford pear. Very formal appearance.
Crapemyrtle Lagerstroemia indica Height - 5 to 35 feet Spread - 5 to 20 feet Growth rate - medium Hardy zones Beautiful summer flower- ing tree of the south. Blooms white, pink, purple and red. Transplant in spring. Winterkill once a decade in north Arkansas

Natchez L. x fauriei hybrid
Southern Magnolia Magnolia grandiflora Height ft Spread - 80 ft Growth rate - medium Beautiful specimen but needs lots of room. Long lived. Named selections available
Magnolia Little Gem
Saucer Magnolia Magnolia soulangiana Height - 35 feet Spread - 25 feet Growth rate - slow Hardy zones Blooms very early and flowers often destroyed by frost. Many hybrids and selections.
Saucer Magnolia Star Magnolia
Japanese Flowering Cherries Prunus yedoensis Height - 35 feet Spread - 35 feet Growth rate - medium Hardy zones Must have good drain- age. Susceptible to a host of insect and disease problems but among the most beautiful small trees when in bloom in the spring.

Select Disease Resistant Crabapples Major diseases of crabapples in Arkansas include apple scab, fire blight, and cedar apple rust Resistant selections include Prairie Fire, Callaway, Donald Wyman, Sparkler, and many others Spraying is not recommended for landscape plantings unless in really critical site. For apple scab spray with fruit fungicide at bloom drop and twice as new growth appears.
