Can anyone ID this pink flower please?

madpenguin

My daughter grew this from a packet of 'Pink flower mixture' seeds.
Can anyone identify it please?

Campion, possibly

madpenguin

Not Campion,the notch in the petals is not deep enough for that.
Thanks anyway.
The seeds I think were 'garden' plants rather than 'wild' if that helps.

Might be Silene coeli-rosa. I think a Silene.

Common corn cockle maybe

Common Corncockle has pointy leaves around the flower

I think another poster was querying a very similar looking flower which I thought originally was the Great Willowherb, but it turns out the flower was a Silene Coeli-Rosa, and your one looks like that too.

Still not sure if it is any of these suggestions.
Silene Coeli-Rosa looks similar but the petals overlap,which my flower does not,the petals are separate. Possibly though a Silene of some sort.
The corncockle also looks similar but has pointy green sepals behind the petals,mine does not.

Nut knows her onions.

Pretty sure it's not an onion.  
I'm fairly confident re Silene because of the calyx but no further than that
