This past weekend was the annual Water Lily Festival at the Kenilworth Aquatic Gardens. I had no idea D.C. even had water lilies! They were absolutely stunning and the prettiest color of pink. I would highly recommend checking them out if you are in the area. You can find location and more details on their website.
