In this photo taken Monday, March 19, 2012, George Waters, an agricultural science research technician, gives a tour of a greenhouse at the National Arboretum where root cuttings of cherry trees have begun to flower, in Washington. The pink and white cherry blossoms that color the U.S. capital and draw a million visitors each spring began with trees that have survived for a century. It was 100 years ago this month when first lady Helen Taft and the Viscountess Chinda, wife of the Japanese Ambassador, planted two Yoshino cherry trees on the bank of Washington's Tidal Basin. They were the first of 3,000 planted as part of a gift from the city of Tokyo as a symbol of friendship. The original pair still stands, along with about 100 of the original trees transported from Japan. (AP Photo/Jacquelyn Martin) less
