Fragrant snowbell (Styrax japonicus) is a small deciduous tree with extremely fragrant white spring flowers. "The flowers are little but cover every limb from head to toe," says Roethling. "It’ll make a wonderful statement as a stand-alone or in the back of a perennial bed." Its grey bark and gumdrop-like shape give the tree interest during winter months.

One of the best performers during hot, dry summers is crepe myrtle (Lagerstroemia spp.). "With so many to choose from, one can find the right color and size to best suit their garden," says Roethling. "It’s one of the last summer flowering trees to leaf out. In June, July, and August, large panicles burst—from white to many shades of red and purple." In fall, some leaves are orange, and the panicles go from flowers to small, rounded capsules. Crepe myrtle offers winter interest thanks to its cinnamon-brown bark that exfoliates and intensifies in color.

Often confused for a hydrangea, Chinese snowball viburnum (Viburnum macrocephalum) is a showstopper in the front yard. "In late spring, large white flowers cover the plants so long as they are not in too much shade," says Roethling. "Some re-flowering can occur in fall. The flowers come out green and, when fully open, brighten to a giant white, snowball-like inflorescence." This tree variety does well with pruning should it begin to outgrow its space.

Flowering dogwood (Cornus florida) boats beautiful white, yellow, or pink flowers in early spring. Native to eastern North America, the blooms on this understory tree will attract butterflies and bees to your yard, while songbirds come to snack on its red fruits, which appear from fall throughout winter. Commonly found in woodland margins, flowering dogwood can be challenging to grow in a landscape setting, but its beauty is well worth the extra effort.
