Are these weeds or Viola seedlings?

During the winter my violas produced loads of seed pods which I left in the soil until spring. Now primarily around the villas but also in some of the other pots I'm getting these small seedlings. I can't tell if they are weeds or Viola seedlings though. Does anyone know?

 

Hello, they look like Violas to me. You're going to be busy pricking that lot out

 

Thanks Noisette47! Should I be picking them out if they are Violas? That's what I'm trying to grow there, but maybe they'll be overcrowded?

 

Yes, they'll need thinning out. If you don't do it, they'll do it themselves. You could pot some up into seed trays or small pots to grow on and plant elsewhere?

 

Ok thanks. I'll try that.
