Plant ID please

Got a pack of bedding plants last year to fill a bit of space in some tubs. They never flowered but over winter have gone wild and taken over the tubs! Any idea what they are?

Are they tall or flat? If flatter, might be dianthus

Agree, could be a perennial from last year, dianthus or wallflower or some form of Michaelmas daisy? (or could be a sneaky weed disguising itself as desirable. ) looks healthy, I would let it be and see what develops, unless you need the pots for something else.

It’s pretty flat. It can stay I was just curious. I’ll Google your suggestions. Thank you

Looks like sweet William.

I agree with Sweet William.

Sweet William was my first thought.

Should I thin them out or leave them be? They seem very crammed into the pot they are in but don’t want to damage them?

They look pretty happy to me - I'd leave them alone now. They are biennial so will flower this year and that will be that.

Lovely. Thank you. I will leave them
to do their thing

No, they’ll keep going as long as you let them. I’ve got a Sweet William that’s been flowering every year for years. Biennial is being used here to mean that it doesn’t flower until the second year, and that we usually choose to throw it out, not that it’s truly biennial, flowering second year and then dying, like foxglove or mullein.
