They are invasive trees that severely impact native biodiversity. They are fast growing, producing soft wood that breaks in storms. They are messy because they drop branches all over, and often.Originally Posted by catherine
These trees are on my state’s list of invasive species:
Purus Calleryana (Gallery Pear)—until recent years, widely used in landscaping
Ailanthus alrissima called Tree of Heaven amoung other names. These grow in 3” of soil taking root in roofs and brick walls in my city.
Honey Locusts sprout all over my gardens in Hermann.
My dad used to consider Chinese elms to be junk trees. I don’t see many of those anymore so I think people are not planning them and they’re pulling them up when they show up.
Some of the maple trees around here are pretty awful as far as being fast growing and dirty, but I don’t know which species they are.
These are just a few examples.
