I've not seen T. fruticosum in person, only paniculatum, but the pics I can find show a bigger flower and many less blooms per inflorescence on fruticosum.
T. paniculatum is native in SE US. T. fruticosum/triangulare is not, though is reportedly present in FL, on USDA.
Hi & welcome @Steve923
! T. paniculatum can be vigorous and exuberant in ideal conditions, but can't invade its' native territory. In the case of the asked-about plant, assuming it is T. paniculatum, it is growing in a native location. Your profile does not say where you are, but if your location is one where this plant is not native and it is taking over an area, that would be invasive, as a technical term.
