I'm in central Ohio. Unfortunately, I forgot to take photos of what was planted in this area last year, so I don't know what this is coming up. Right now they are about 10 inches high. The leaves are opposite and smooth. They are ovate in shape and both the stems and the leaves are somewhat fleshy, but not like succulents.

Sedum?

Hey, Pirl! No, not a sedum.

Silene armeria - catchfly?

Hi!

I don't grow that one so can't help with an ID, sorry!

Looks like Lychnis is a possibility. Lychnis chalcedonica? Or similar?

Hmm, the foliage resembles Lychnis chalcedonica; I've never grown it, though, so it would be odd for it to show up in such profusion.

Looks a lot like my soapwort.

It looks so darn familiar to me! I can't put my finger on it.

Could it be Jupiter's Beard, Centranthus ruber?

Today in my garden

Your plant
Looks like catchfly to me

The Lychnis genus no longer exists. Its species have been reclassified as species of Silene.

Instant extinction!

Silene armeria or Sweet William Catchfly is in the database. I've never heard the reference to Sweet William before. When it flowers, if you grasp the stem just below the flower base, you'll find a sticky bit. Thus the name Catchfly. My father got a free packet of flower seeds in the early 1950's. From then on we knew it as "Dad's Surprise Package Flower." It followed us in all of our moves, not that we ever intentionally took a plant with us. I finally identified it a few years ago. I find it to be biennial - it will seed and start it's plants in the fall, and continue coming up all spring.
They settle themselves in wherever they can. But they are easily removed, if not wanted.

Hey, everyone! Sorry I didn't come back sooner, but I was traveling for work. You are correct that it is catchfly/silene. I think I grew it years ago, and maybe had one solitary plant come up in that bed last year with some other plants. That's all it would have taken.

We had water line repair work done, so it's possible that when the trench was dug and everything was upset, some seed managed to find its way over to that area. I don't know how long it remains viable.

Kimberly , nice to 'see' you here!

Great to see you, too!
