Friendship Cemetery in Columbus, has been called “Where Flowers Healed A Nation”? On April 25, 1866 the ladies of Columbus, Mississippi decided to decorate both Confederate and Union soldiers’ graves with garlands and bouquets of beautiful flowers. As a direct result of this kind gesture, Americans celebrate what has come to be called MEMORIAL DAY each year.
Celebrated in Boalsburg, Pennsylvania in 1864.
