how big were they when you planted them ..

if you want them denser.. i dont know how dividing them would accomplish that.. seems to me.. it would just set them back ...

in my experience.. peony are slo motion plants ... they just dont grow like some of the more exuberant perennials ... i dont really see anything wrong with the plant above.. 2 years after planting ... unless of course.. you bought huge plants to start with.. but you dont say they have reduced crowns.. you just say there arent as many as you would like ... patience

as to buying more .. well.. you have the sapce.. buy away ... but i wouldnt necessarily jump to replacing these .. unless that makes you happy.. and if so.. be gone ..

btw: did you bare root them at planting.. if not.. then you really dont know if what you planted were equivalent ... perhaps the slower ones.. need to grow a bigger root mass to catch up ... so.. on some level it might be comparing apples to oranges ... if you get my fruity drift ...

I bought them already established in pots at a nursery. I didn’t really pay attention to how many eyes were in each pot as they were already growing and I was a novice, still am. I’m pretty sure the 6 that are there now is what I planted. I guess my question is as they grow older do they grow more eyes?

This is how one of the denser plants looks. Maybe the one I’m questioning is a slow grower.
