I do not actively propagate Tier 1 invasive plants on my site and take action to control their spread. Five top offenders are Chinese tallow tree (chicken tree), Chinese privet, Japanese honeysuckle, Elephant ear, Yellow flag iris. (For a complete listing of Tier 1 invasives, go to https://www.wlf.louisiana.gov/assets/Conservation/SWG/Files/15_WAP_2017_Ch_6.pdf).
