1937
The Legislature adopted the White Trillium (Trillium grandiflorum) as Ontario’s official flower in 1937. The move to select a provincial floral emblem was influenced by an interest to find a national flower suitable for planting on the graves of World War I Canadian service men overseas, although a national flower was never chosen.
