Adding the right flowering trees and shrubs to your landscape will ensure an explosion of color in early spring. Here are some suggestions. Dogwood (Cornus). Ranging in height from 25 to 70 feet and producing white, pink, or pale yellow flowers, dogwood can fit almost every tree need. If anthracnose is a problem on flowering dogwoods (C. florida) in your locale (check with your local garden center), consider the more disease-resistant kousa dogwood (C. kousa). It blooms with showy white bracts a few weeks later than flowering dogwood. Magnolia (Magnolia). For hardiness, pest resistance, and tolerance to air pollution, choose a mag-nolia. Depending on the species, flowers can range in color from white to light pink, deep pink, cream, and yellow.
The saucer magnolia (M. x soulangiana) and the southern magnolia (M. grandiflora) tie as the most strongly scented. Goldenchain tree (Laburnum x watereri). When in bloom, this tree is a showstopper. The 24-inch-long yellow racemes grace the branches in late spring and early summer. Grow this 20-30-foot-tall tree upright, or draped wisteria-fashion over an arbor in a site screened from strong winds. Flowering cherry (Prunus). Flowering cherry is a favorite for year-round interest. In spring, trees are loaded with clouds of pink-and-white blossoms. Fall brings a whole new range of vivid leaf color, and the satiny bark is attractive all year. Japanese flowering cherry has a short to medium stature, with spreading branches. One outstanding cherry is 'Amanogawa' (Japanese for Milky Way), which displays bouquets of fragrant light pink blooms in spring.
