(DC) (Rock Creek Conservancy) This time of year in Washington, DC is all about the Cherry Blossoms, but before the cherry trees on the Tidal Basin were a thing, the roots of DC’s cherry blossom history got planted in the Rock Creek Valley. Come for a short ranger talk about the history of cherry trees in Washington away from the bustle of the Tidal Basin and then enjoy a walk up to 2 miles through some of our trails to see what’s blooming this spring in Rock Creek Park.
