Next Tuesday, take an extended lunch break to see the first lady herself grace Politics & Prose. Michelle Obama will be signing her best-selling book, American Grown: The Story of the White House Kitchen Garden and Gardens Across America (Crown, $30), at the Chevy Chase bookstore on May 7 between 11:15 a.m. and 12:30 p.m.

In American Grown, Obama describes how she has turned her love of gardening into a White House project, revamping the “first garden” into an exemplar of healthy home-grown foods that can be used for cooking and teaching. She worked with young students, regional gardeners, chefs, and members of the military to make the garden what it is today. She also writes about inspiring gardens across the country, remarkable not just for their beauty, but for their rich background stories and the people who brought the healing quality of gardens to their communities. The New York Times Book Review called Obama’s book “a warm and personable record of her very public garden’s changing seasons.”

A wristband is required to attend the signing. They will be available with purchase of the book at Politics & Prose (5015 Connecticut Avenue NW) starting tomorrow at 9 a.m. Additional restrictions to note are that only one wristband may be purchased per customer, only one copy of American Grown may be signed per customer, no other items may be brought in for signing, and a security screening form must be completed at the time of purchase.

Obama did not take an advance on American Grown; all author proceeds will go to National Park Foundation and be put toward programs that promote gardening and healthy eating, including the continued success of the White House Kitchen Garden. The above restrictions may change, so questions should be directed to the store by calling (202) 364-1919.
