Washington has been the national epicenter of spring ever since the planting of the original 3,000 cherry trees gifted to the city by Tokyo Mayor Yukio Ozaki, so you probably already have the National Cherry Blossom Festival on your spring calendar. Less-well-known is the Flower Mart that has adorned the grounds of the National Cathedral on the first Friday and Saturday of May for every year since 1939.
For culture buffs, the annual embassy tour is a can’t miss event spread over the first two weekends in May. First is the Around the World Embassy Tour, where you can wander down Embassy row sampling cocktails and music from around the world. The following weekend is the EU Open House, where the European Embassies host free performances and sell food and wares from their home countries.
