Is there a more biodiverse place in North America?

I swear, every spring I am complety astounded by the variety of plant life here. Bursting out of every crack in the earth it seems, blooming and climbing up and around structures. Enormous Redwoods and Sequoias just hanging out in neighborhoods. Evergreens and decidious all mixed together. I feel like every time I go on a walk I see a new species of tree or plant. Its insane really. Im wondering if there are other places in NA that have a similar level of biodiversity and such dramatic springtime blooms. Or are we just super duper special…
