Bellis perennis are your common or garden daisies, they are perennial. I think all those large flowered bedding daisies are cultivars of that and should be perennial as well.
However I don't grow them and it's possible they're hybrids.
If the leaves are spreading in the pot it's a perennial.
Don't let them seed as over time they will seed back to the species which some classify as a lawn weed.
