Hi Miss_ee
@plantladylin Except for the seeds/flower this sure seems like you were right about Tree of Heaven. Penn State Extension lists every problem this tree causes which really seems very close. Sometimes on a very fast growing tree the leaves change even shape and placement branch to branch. Male trees do not produce seeds. Both male and female produce some kind of flower in spring. Pictures on different invasive web sight listings match these pictures better than NGA thumbnail. May everyone be blessed with extraordinary weekend!
