The 67-year-old wife of Prince Charles met with Floral Angels - who take the blooms from weddings and other events and recycle them for hospices, shelters and senior homes - in her London home, Clarence House yesterday (01.07.15), and crafted a bouquet from delphiniums and other native British plants to be taken to a London branch of Maggie's Centre, a cancer charity of which she is patron.

Camilla asked the team: "Do you ever put lemonade in your water? If you put it in then [the flowers] do keep longer and it helps keep the water clear."

The blooms that Camilla was using had been provided by the Duke and Duchess of Cambridge's royal wedding florist Shane Connolly and were being "recycled" from Tuesday evening's party for Elephant Family, a charity set up by Camilla's late brother, Mark Shand, that seeks to help the Asian Elephant.

Speaking to, Floral Angels' joint founder Frances Hunter, who joined her colleagues Julie Ritter, Amanda Romaine and Katrien McCarthy at Clarence House said: "(Camilla) is a very experienced flower arranger and she very much enjoys doing it herself. We deliver the bouquets in recycled jars and tins and Clarence House kindly gave us some of their jam jars."

It was very much a flower-filled day for the Duchess, as she later headed to Hampton Court Flower Show.
