Thousands of volunteers placed approximately 230,000 evergreen wreaths at Arlington National Cemetery as part of the Wreaths Across America program on Dec. 13, 2015. The holiday tradition began in 1992 with 5,000 wreaths, and now has expanded to more than 1,000 fundraising groups in all 50 states, who place wreaths at hundreds of cemeteries and other military memorial sites across the country.
