In 1960, Squires of the Knights of Columbus in Mexico, the United States, and Canada came up with the idea of honoring Mary with a rose. Mary used the rose as a sign of her appearance at Guadalupe.
They started at London in Ontario, Canada, and ended at the Basilica of Our Lady of Guadalupe in Monterrey, Mexico, presenting Mary with a live rose.
The following year, both a bronze rose and a silver rose were used. The decision was made to use a silver rose in the future. The silver rose is crafted from a real rose.
