Coralberry

while trying to identify a wildflower, I ran upon this listed under "CAUTION INVASIVE SPECIES"
well, at least now I know what it is!

it's called coralberry, or christmas berry. (Arsidia crenata)
"Coral ardisia is listed by the Florida Exotic Pest Plant Council (a non-governmental organization) as a category I species, defined as an introduced species that is invading and disrupting native plant communities in Florida. In many areas, coral ardisia has become a significant pest. " - floridata

Fascinating. However I find no disruption present so, I am not going to interfere with this plant's life.
