Tree of Heaven (Ailanthus altissima) on Aug 23, 2026

Description of specimen

Submitter does not have a specimen

I just moved into this home and have around 5 to 10 tree of heaven clones popping up around my house and driveway. There is one tree that is more established which may be the primary tree but I'm not certain and would appreciate any help that may be available.
