White Dogwood (Cornus Florida)

No matter the season, the white dogwood is ready to put on a show. "In spring, it produces white flowers," says Shah. The blooms, which are a mainstay from March through May, are actually "bracts" or modified leaves featuring small blooms at the center. These are a thick, creamy white with a golden-green bud; pink spots tend to appear on the tips of each petal.
