First lady Melania Trump planted an Eisenhower oak sapling Monday afternoon on the White House’s South Lawn, along with two descendants of former presidents.

Mary Jean Eisenhower, the granddaughter of former President Dwight Eisenhower, and Richard Emory Gatchell, Jr., a fifth generation grandson of former President James Monroe, joined the first lady, who was wearing pink heels and a floral skirt.

“It’s a very special day. I want to thank the National Park Services for doing an amazing job in keeping the White House grounds in beautiful shape and the whole of America in good shape,” Trump said, according to a press pool report.

The planting coincides with the White House Historical Association’s Presidential Sites Summit and other descendants of former presidents were also present to watch the planting.

“I also want to thank the White House Historical Association for putting together the summit. … It’s the first day,” Trump added. “So good luck with the summit. Thank you all for coming. It’s a beautiful tree that we will plant today.”

The sapling, which was intended to take the place of a tree that had been damaged earlier this year, was uprooted from the Eisenhower oak near an East Wing garden, which was originally established by former first lady Jacqueline Kennedy.
