We took Dorothy to the airport today and she flew up to Boston. From the airport, we decided to pay a visit to Kenilworth Aquatic Gardens on the Anacostia River in northeast Washington. The lotus (Nelumbo nucifera) was past peak, according to the ranger on duty, but they were still blooming pretty freely. The water lilies were a little more past, but there were quite a few even of them. We also got a good view of a great blue heron (Ardea herodias) wading in one of the ponds. It was a beautiful day, not too hot and with a wonderful breeze.
