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
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
Eastern Redbud Cercis canadensis Height - 25 feet Spread - 25 feet Growth rate - fast Hardy zones 3 - 9 Best in full sun. Transplants best from container grown plants. Seed pods unsightly in winter Trunks can split in ice storms
Bradford Pear Pyrus calleryana Height - 40 feet Spread - 35 feet Growth rate - fast Hardy zones 4 - 9 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.
