Suckers come from the root stock. Anything from stems is the grafted plant.
(if it is grafted, roses can be grown from cuttings and are then on their own roots and anything coming up will be the same as the plant.)
seven leaves doesn't mean sucker. that's a myth
Some plants flower on the growth they made in the previous year.
Don't cut them off, see what they do this year
