Camilla spent the day at the Garden Museum and met volunteers from Floral Angels, a charity that recycles donated flowers from events and arranges them for use in hospices, shelters and care homes throughout London. During the outing, she remembered both Prince Philip and her father, Major Bruce Shand, who died 15 years ago on Friday.

"I'm very honored to be here, to be doing something I know they both would have appreciated," she said.

Prince Philip's grandson Prince William and granddaughter-in-law Kate Middleton also remembered him, sharing a new photo of the Queen in the gardens of Windsor Castle. It was announced Wednesday that the monarch, 95, was recently presented with a pink rose that was specially created to mark the Duke of Edinburgh's centenary.
