The Cherry Blossom trees on the Tidal Basin were a gift from Japan in 1912. They signal the coming of spring with an explosion of life and color surrounding the Jefferson Memorial on the Tidal Basin in a sea of? pale pink and white. Exactly when the buds will open is not an easy question to answer, but the National Park Service Regional Horticulturalist provides updates on the expected blooms which have bee accurate in the past several years. See the NPS bloom schedule page for a detailed explanation of the bloom schedule and graphics explaining the stages of blooming of the trees. Annually with the expected peak of the blooms the Cherry Blossom Festival occurs with many associated events.
