Which country does Maple Leaf Country refer to?

The leaves of maple, the national flower of Canada. There are many maple trees in Canada, which is called "the country of maple leaves". For a long time, the Canadian people have deep feelings for the maple leaf and regard it as the national emblem. There are three red maple leaves in the middle of the national flag. The national anthem is "Long live the maple leaf" and the national tree is maple. For hundreds of years, the Canadian people have been so attached to the maple leaf because it is beautiful. Every late autumn, orange-red, fiery red, bright red and crimson maple leaves are all over the mountains, magnificent and spectacular. Maple leaves not only have ornamental value, but also have economic value, especially sugar maple and black maple, which are good raw materials for boiling syrup. The sugar content of maple juice is 0.5% ~ 7%, as high as 10%. A maple tree with the age of 15 can continuously produce sugar for more than 50 years every year. Every March, Canada holds a traditional "Maple Sugar Festival", where people can taste sweet maple sugar. In this way, it is reasonable for Canada to designate the maple leaf as the national flower.
