This is all nonsense.>From a metaphysical philosophy perspective I agree.
The plant is not invasive, no plant represented in the genus Iris, is.You'll need to define invasive... all plants 'invade'. Some plants form monocultures in some environments due to their competative abilities. You could easily shape your definition of invasive to exclude the Genus Iris if you wanted to.
The potential historical origin of the Fleur-de-lis is a side track to making a level headed decision about plant selection.
See bottom of this links page...http://www.heraldica.org/topics/fdl.htm. and

This plant has demonstrated its usefulness for many centuries and if it isyes it has a history of human use over its range... WE HUMANS like it... the plant also provides goods and services to some other creatures. If it replaces a variety of vegetation accross a landscape it may change the composition of those goods and services... some creatures may be served less well, others served better. For example, The bulk of our native frogs appear to depend on thin leaved plants in sunny shallow water (Juncus effusus serves well...) for their egg laying. Iris does not offer that service, and may replace plants that do provide that service. Thus reducing opportunities for frog egg laying. Might not be a big deal, might be a really big deal if frogs are stressed by other factors. Don't think we really can tell. The services of a plant is not provided to "the environment" but rather to other components of the environment through beneficial or detrimental relationship (its not the number of components but the relationship between them). I think your invocation of the environment is a smokescreen.
growing well then it is
providing a service to the environment.
The above links demonstrate it's other values beyond it'sit has european cultural value... should we assist its spread?
biology.
Plants can survive each other better than they can survive our activitiesThis is likely true in many cases... and furthurmore many invasive/opportunistic plants follow in the footsteps of our wonton destruction, so turning about and then spraying the plant could be double the crime. Furthermore, in wetland environments our abuse of the land results in changing hydrology increasing the dynamism of the plant communities, forcing them to seek a new equilibrium.. we create the vacant niches. Kneejerk extermination of Iris is wrongheaded. I wasn't talking about Iris pseudoacorus extermination, but rather assisting in its dispersal.
placing
billions of tons of cides into the environment each year. What hubris to
legislate this, our
policies are truly the invasive.
