Invasive plants are a serious concern ecologically and economically yet nurseries continue to sell them within Virginia likely because they are cheap to propagate. While labeling is likely insufficient to address the issue in full it would at least help raise awareness on the issue. I support Margret Fisher's comment on how to make sure such labels are of value in raising awareness and suggesting alternatives as commenter Sheryl Smith  suggested would also be a good idea if space can be found.  The consequences of these plants need to be made more widely available to people who generally rely on "expert" opinions of sales people to make their purchases or the suggestions of friends and family who have been referred to these plants by said "experts". Finding ways to address both the peer pressure/industry standard one size fits all solutions will likely bee needed in addition to taking efforts to raise awareness of the issue, but for a first step this proposed regulatory action is progress.
