Clary or weed

Have had very poor germination with my commercial clary seed. However have noticed loads of self sown seedlings in the patch of garden where I had clary last year. Have put quite a few of these in multipacks ready for planting out later. BUT, now I’m not sure if they are clary seedlings, the leaves look a bit rounded. What do you think? And if not clary, what weed could it be?
The garden ones are on the left and the commercial ones are on the right 
Thanks.
