Mimosa Trees
Mimosa trees produce gorgeous leaves that make them very desirable. Native to the Middle East and China, they were brought Stateside and caused some trouble. They attract many types of insects like moths and webworms. Their seedling pods are quite large and fast to germinate, even in the winter, which means they can spread quickly.
Sweetgum Trees
Sweetgum trees are native to the southeastern area of the United States. These tall trees grow up to 75 feet and have beautifully colored leaves. However, their seedling pods are tough to remove, and their roots are invasive. Additionally, these trees attract many birds. If you have any other plants growing in your yard, avoid adding in Sweetgum trees.
