Floral Fighters?

'Rebel' Botanists, armed with chalk, are reportedly putting names to the plants emerging between pavement slabs and at roadsides in the Covid-19 lockdown over Europe (https://www.theguardian.com/environment/2020/may/01/not-just-weeds-how-rebel-botanists-are-using-graffiti-to-name-forgotten-flora-aoe). One such campaign, More than weeds, is fronted by a French Botanist living in London (who, naturally, uses the English names for the vegetation). She  reportedly hopes to remind people than these growths are part of our natural world re-emerging with reductions in the urban spraying of herbicides. It has been suggested, however, that these educational activists might well be prosecuted for their graffiti.
