Norway Maple Tree
The Norway Maple tree can grow up to 60 feet tall along with a trunk that can up to 7 feet in diameter. It was brought to the United States in the 1700s as a tree meant for parks and streets. However, it has since invaded forests and competes with native sugar maples. This tree also causes less wildflower diversity in areas where it thrives as compared to sugar maples.

Princess Tree
The princess tree, which is sometimes called the Empress tree, is absolutely beautiful but also very aggressive. Not only can it grow up to 60 feet high, once it reaches 8 to 10 years, the tree is capable of producing even up to 20 million seeds, which are then dispersed by wind and water. This tree is also quite fire resistant and also has the ability to grow from bugs on stems and also roots. That means that it can quickly trample over native species in its way.
