Gardeners and landscapre professionals create colorful displays and care for hundreds of acres of lawns and plantings. All of these efforts are directed at making the work of the Congress, the Supreme Court, and Library of Congress – and the experience of the millions of visitors annually – as smooth, efficient and enjoyable as possible.
