A lecture and book-signing for “All the Presidents’ Gardens: Madison’s Cabbages to Kennedy’s Roses - How the White House Grounds Have Grown with America” by New York Times bestselling author Marta McDowell will be held at 1 p.m. Oct. 15, Lehigh Valley Heritage Museum, 432 W. Walnut St., Allentown.

The 18-acres surrounding the White House have been an unwitting witness to history. Kings and queens have dined there, bills and treaties have been signed, and presidents have arrived and departed.

Throughout it all, the grounds have remained not only beautiful, but also a powerful reflection of American trends.

In “All the Presidents’ Gardens,” McDowell relates the untold history of the White House Grounds, starting with plant-obsessed George Washington and ending with Michelle Obama’s kitchen garden.

McDowell reveals fascinating tidbits about Lincoln’s goats, Ike’s putting green, Jackie’s iconic roses, Amy Carter’s tree house, and much more.

McDowell teaches landscape history and horticulture at the New York Botanical Garden.

Copies of McDowell’s book will be available for purchase and the author will sign copies following the presentation.

This presentation is held in conjunction with the museum’s exhibit, “The American Presidency.”
