Ask-a-Dave's-Gardener: Canterbury bell or weed, 1 by Allofhisbeauty

I sowed Canterbury bell seeds last spring and they have survived the winter. I’m looking forward to seeing what color they will be! However, there are a lot of plants around the ones I’ve identified that look like Canterbury bell foliage but the base of them aren’t the same. I don’t want weeds smothering the new Canterbury bell plants and don’t want to pull them up if they are the same. Please help🙂
