We have a couple of GCs round here, but at least 4 "nurseries." 3 definitely grow a lot of their plants, the others I think grow-on some. None is specialised & sell a good variety of things, but at least if something's grown there then I know it's suitable for my conditions. So if you're growing your own plants then it's a good selling point for the local market, as people will know that they're suitable.
Knowledgeable & friendly staff would certainly make me come back - I'd rather pay a little bit more & be treated in a friendly manner than go to somewhere cheap & just be regarded as another "punter." Also if a proprietor treats their customers well, then they probably look after their plants too!
I'm 100% with fidget re what to sell or not!
One local nursery has started grouping their plants into their suitability, eg windy, seaside, boggy, etc. I suppose it's good for people who don't have much gardening knowledge, or time to read labels, but I prefer things in alphabetical order - having done some research first. I found it most confusing.
