The Chelsea Flower Show played host to several members of the British Royal Family Monday. Queen Elizabeth, Prince Philip, Prince Charles, Camilla, the Duchess of Cornwall, and Prince Edward all took a stroll around impressive floral exhibits.

One garden designer, Isabelle van Groeningen, said Charles was "particularly interested in the grasses." While Camilla - wearing a patterned shawl over a two-piece lilac jacket and skirt - was taken with sculptures of flowering grass.

Queen Elizabeth was handed an orange and blue bird of paradise flower and a burgundy arum lily during her walk round the pavilion.

Britain's Princess Alexandra and the Prince and Princess Michael of Kent also took in some of the colorful attractions.

Meanwhile, Prince Charles has commissioned a piano concerto in honor of the late Queen Mother, his grandmother. Written by composer Nigel Hess, the 23-minute piece is in three movements said to reflect key traits of the Queen Mother's personality.

The piece will premiere in July at a concert organized by Music in Country Churches, of which Prince Charles is a patron.
