Baby plant wiki

Something I’d love to see built but don’t currently have time for is a wiki of baby plant pictures. I often can’t tell what plants are until they’re larger with adult leaves and characteristics. That often leads me to pull plants out of the garden that turn out later to be something I wanted. I’ve tried using a few different apps on the phone but they’re often wrong.
I haven’t found any resources on the Internet for this so I’m posting here to see what others think.

This seems like a worthwhile enough post to revive it. Anyone have any resources like this? I do image searches online for young plants of a given type but I mostly don't get good results. My PictureThis phone-app seems to know juvenile plants, but it's not perfect and unfortunately doesn't do much to tell me what level of confidence it has.
