This photograph of one of the Obama family's pet dogs, Sunny, in the Rose Garden of the White House was taken by Matthew D'Agostino on May 20, 2015. The Rose Garden is located on the west side of the South Grounds, just outside the Oval Office. It has gone through several incarnations: a vegetable garden in the first part of the 19th century, a “colonial” garden in 1902, and then replaced with a rose garden in 1913. In 1961, President John F. Kennedy wanted to expand the garden for official functions and events. His idea became the Rose Garden, designed by horticulturist, gardener, and close friend of the Kennedy family, Rachel Lambert "Bunny" Mellon. The garden was installed the following year, becoming a green theater for official ceremonies and a special place for the first family’s private enjoyment.

This photograph by Harris & Ewing shows President Woodrow Wilson's sheep grazing on the South Lawn. Instead of using groundskeepers to cut the grass, the sheep grazed on the White House lawns. The flock grew to 48 at its peak. The wool sheared from the sheep was sold at auction to raise money for the Red Cross.
