National Arboretum Azalea Walk

Admirers come to the U.S. National Arboretum's Azalea Collection every spring to witness one of Washington's premier spring attractions. Thousands of azaleas cover the flanks of Mount Hamilton in a blaze of color. The first warm days bring out the flowers, and the slopes take on a surreal, almost luminescent glow. Few shrubs have more impact on the spring landscape-azaleas are an enduring favorite in gardens throughout the country.
