Sunflower? I don't think so

[Jebusfathead]

So I've been growing this 'sunflower' for about 2 months now, and one of them opened up to show pink petals, so I'm wondering what flower actually is this?

[!potatoes!]

definitely not a sunflower. can you get an in-focus pic of the leaves?

[rainbowgardener]

better pics would help, but possibly a cosmos? Definitely not sunflower.

[Jebusfathead]

Hopefully this is a bit better quality image of the flower.

[rainbowgardener]

Showing us the leaves also would still help.

That flower is quite distinctive, but I'm having trouble finding it.

The yellow sundrops look pretty much like that:



There is a pink version of those, but the pictures of them seem different, not so notched:



note thin leaves going all the way up the stem:



wild geranium also has five petalled pink flowers that are sometimes notched, but not as deeply as yours:


here's their leaves:

Here are some more photos of the leaves, couldn't get a good angle cause there are other leaves in the way.

OK, so this is starting to make me crazy. It isn't any of the things I have suggested so far.

I feel like I should know it and it is very distinctive.

I have PM'd on your behalf a couple of our members who are very good at plant ID's, maybe we can get some help here!

That certainly reminds me of Viscaria. I grew it a couple years ago and that is what comes to mind. Don't have a picture to share...sorry. Charlene

[rainbowgardener]

Good job! Thanks, I think you nailed it!

It's hard to find a good picture of it. This one is a slightly different species, silene carolina (also called sticky catchfly)



Silene viscaria, the sticky catchfly[2] or clammy campion,[3] is a flowering plant in the family Caryophyllaceae.

Silene coeli-rosa - Also known as Viscaria oculata.

[Jebusfathead]

Yeah, that's pretty much a 100% copy of the one I have, thanks for all your help

[Plantdoctor_IA]

You're welcome. I loved the Viscaria flower, but the next Spring I found thousands of them every where, so opted not to plant it again. Charlene

Well done @rainbowgardener my first thought was Lychnis, but it can be Silene too...
