Reminds me of Silene sp like Silene flos-cuculi (Lychnis flos-cuculi) the Ragged Robin

Close up...

very pretty and its growing in both full sun and dense shade... the plants in shade are doing better than full sun.

I love seeing their flower petals, as if there are 5 little pinky person lay in circles, with their heads stuck in the center. The kind things I did with high school friends long2 time ago while hiking, lay on ground under trees and the sixth person climb the tree trying to take pictures from above,.... nowadays kids have the flying drone to get it even better.

That seems to be correct. It's so pretty
The base of the plant Is barely an inch tall, tons of tight Narrow sword shaped leaves, Maxing at an inch with foot tall flower stems.
I want this plant everywhere!

I read it's perennial... but not in which zones- so that means squat...
nothing is perennial in every zone.

I'm 6b, but that's not really reliable where I live. I could throw a rock out by bedroom window and nearly hit the Hudson River where it meets the Long Island sound at the head of manhattan. I also get a lot of deep hard cold blowing down from the Great Lakes and a lot of Caribbean warm water coming up from the Gulf Stream so every winter is different.

Hi Paula,

I have had home-hybrid zinnias that reminded me of your Ragged Robin Lychnis.

Actually, your Ragged Robins reminded me of those weird zinnias. Re-crossing zinnia specimens similar to those might get even closer. However, the zinnia plants would still differ a lot from the Lychnis.

It's a very common wildflower in the UK. Really beautiful plant.

Ragged Robin (Silene flos-cuculi)

Your zinnia are beautiful.
I'm sure it's Silene/ragged robin bc although the flowers are reminiscent the leaves/overall growth habit and size are very different.

ragged robin, perennial here.
