Looks like Moss Rose to me....

Portulaca pilosa, common name Kiss me Quick. Couild be a named variety, seeing the special coloring. =)

I think it's a Portulaca grandiflora. P. pilosa has TINY flowers, about 100x smaller than that.

Yes, purpleinopp is correct! =) I wasn't thinking...size of bloom. Portulaca grandiflora is a better fit!

You're welcome, but Nancy's comment was what pointed *me* in the right direction. I just knew it wasn't P. pilosa because after admiring that tiny plant in the cracks of parking lots and in the gravel at the side of the road for years, I was finally able to get a good picture and ID it on the NTP forum. It's a native, kind of unusual when it comes to tiny but still showy, noticeable flowers.

A few little pieces of P. pilosa I rescued from the parking lot across the street before it was repaved are struggling (or maybe just going dormant,) but hopefully they dropped seeds in their pot if the mamas don't make it. I adore tiny plants and this is probably the cutest one I've ever seen. I hope to use some in a fairy garden pot next spring.
