How did the red earth of PEI become a symbol of Canada?

The red earth of Prince Edward Island (PEI) became a symbol of Canada due to its unique, rich, iron-rich clay soil, which is not only visually striking but also crucial for agriculture, particularly potato farming. This distinctive landscape is often associated with the island’s cultural identity, as depicted in literature, such as L.M. Montgomery's "Anne of Green Gables." The vibrant red soil encapsulates the natural beauty and agricultural heritage of Canada, making it an enduring emblem of the nation.
