National flower, national bird, national tree

I am teaching some young adults, and they have raised some interesting questions . . . . .

(1) What is the national flower of the USA? If there is no national flower, are there state flowers? What about Puerto Rico, Guam, Virgin Islands, etc. those “overseas territories” . . . . . do they have their own territorial flowers?

(2) The national bird of the USA is the bald eagle. What is the national bird of Canada?

(3) Is “maple” the national tree of Canada? What is the national tree of the USA?

Thanks in advance.

I am not sure about the national trees or flowers… I Know each individual state has their own State bird, tree, flower, etc…

you can go to this website to find each one:

Not sure about overseas territories though…

The common loon…I kid you not.

The rose is the national flower of the United States. It is the official flower of New York State.

…and the original bird for the US was to have been the turkey:

Benjamin Franklin, 1784 arguing for the turkey
