This year's Chelsea Flower Show at London's Royal Hospital opens today with a particularly stunning exhibit: a lawn filled with more than 300,000 crocheted poppies from volunteers around the world. Part of the 5,000 Poppies project started three years ago, which recognizes those who have served in war, the poppies were first created by Australians Lynn Berry and Margaret Knight to honor their fathers, who fought in World War II. Slowly, as word spread of their crochet tribute, volunteers from age 2 to 100 began to donate their own handmade poppies made of yarn and buttons in honor of their own friends and family who had served their respective countries. Now, with the help of award-winning designer Phillip Johnson, the exhibit has been set up at the famed flower show, which runs through May 28.

In addition to the carpet of 300,000 poppies that extends over the central lawn, 26,000 stemmed poppies were created specifically for the Chelsea Flower Show exhibit. The more than 160,000 visitors expected this week at the show will experience over 100 floral exhibits from the world's top horticulturists, including a floral arch to celebrate the 90th birthday of the Queen.
