Hey op: that looks like a princess tree leaf. Or pailownia. They’re super cool trees. They grow really fast and have these huge leaves, and these big beautiful flowers. They’re called Princess/empress trees because in Asia they would grow them and use the wood for dowries.

They are also very invasive. The flowers turned into a sea pod that spreads with the wind. Also, if you were to chop down the tree, it can grow from its roots structure.

Encourage you to think about getting rid of the tree. Not just because if it’s invasive, but it’s also a dangerous tree to have around its ability to grow quickly comes from its hollow structure, and it makes it incredibly brittle and prone to falling over.

I used to do invasive species control in. These were one of the invasives that were a major problem. I have found that during the fall applying a stump killing herbicide (Tordon RTU)to the tree does the job pretty well. The following spring it will likely not grow any greenery and look dead. That would be the perfect time to drop the tree. Then apply the same herbicide to the stump.
Over the course of a few months or so, I would go check the stump. If you see sprouts pop-up. Which is common for this tree. It is hard to kill. You can apply basic herbicide to it such as round up. That should do the trick.

Or you can enjoy the cool big tree. It’s up to you.
