Weed??? - Daisy. :D

Got these popping up in greenhouse . 
Hoping that they could be Erigeron karvinskianus.
Husband reckons they’re weeds.
They’re definitely not what was originally in the pot - which was a very leggy lavender!

It looks so familiar! But I haven’t got a clue what it is.

Thanks SC
Just don’t want to waste time and compost pricking them out if it’s just a weed.
And don’t want to throw them away if they’re something worth having.
I guess I play a waiting game!

I don't think its Erigeron as their leaves are much smaller and thinner. Tomorrow, if the rain stops, I'll look for some in the garden to check.
Is it an ordinary garden daisy?

Could well be!

My 'Picture this' plant identifier app says common daisy
