When Cheval Opp retired from IBM, she knew exactly what she would do with her time.
"My whole life at IBM, whenever they would send me anywhere, I would take an extra day or a weekend and visit gardens," she said. "When I realized I'd be retiring and I could do anything I wanted, I knew what it would be."
Now Opp helps travelers and day trippers arrange tours of the many public gardens in the Mid-Atlantic area. She helps choose which gardens to see and how to time the visits.
"This is my second act," said the woman who calls her garden tour company (of course) Cheval's Second Act.
National Public Gardens Day is Friday, when America celebrates the role of these public gardens in promoting environmental concerns. But public gardens have an impact on visitors that goes beyond plant or water conservation and reaches into the spirit.
"Studies show us that even the plant on the window sill is calming," said Opp, who lives in Dunn Loring, Va., and also writes and lectures about public gardens.
"We know that these things are alive, and we are part of their life cycle. And we know if they are alive, we are alive," she said.
The Mid-Atlantic has an abundance of stunning public gardens not only because of the industrial wealth that was once centered in this part of the East Coast but because the climate is moderate enough to support a vast range of plant life.
Choosing the best of them to visit isn't easy. There are dozens in Pennsylvania, Delaware, Maryland, Virginia and the District of Columbia that are worth a day trip.
If you want to see a garden that is beautiful every season of the year, go to Dumbarton Oaks in Washington.
"It is a work of art," she says.

Three generations of the du Pont family lived and gardened on Winterthur's 1,000 acres, and all preferred a garden that made the most of the natural landscape. The last du Pont to live here, Henry Francis, selected the choicest plants from around the world to enhance the natural setting, carefully orchestrating a succession of bloom from late January to November. Even after he turned his former home into a museum in 1951, he kept his garden in private ownership until his death in 1969.

The Chanticleer estate, called the most romantic public garden in the United States, dates from the early 20th century, when land along the Main Line of the Pennsylvania Railroad was developed for those wanting to escape the summer heat of Philadelphia.

Chanticleer is synonymous with "rooster," and the Rosengartens used rooster motifs throughout the estate.

On this site more than 250 years ago, John Bartram, a Quaker farmer, was stopped in his tracks by a daisy while plowing his fields. The plant's simplicity and beauty inspired Bartram and his son, William, to spend the rest of their lives exploring, collecting and seeking to understand all forms of nature. In 1783, the Bartrams issued the first printed plant catalog in America and supplied plants for Independence Hall, George Washington's Mount Vernon, Thomas Jefferson's Monticello, and E.I. du Pont's Nemours.
What's blooming: the Wetlands. Thousands of native wetland plants, including bulrushes, marsh grasses, irises, hibiscuses and marsh roses, have been planted along the lower Schuylkill River.
