Not sure of the name of this small little flower - have seen it before but did not notice the different tones of pink/red. They remind me of pretty little shells. Still raining here - had tornado warnings last night, but they stayed 15 miles south of us and didn't do much damage.
Were they on a vine @milaniet? It looks like Groundnut, which is a perennial vine that grows in wet areas. Take a look here https://uswildflowers.com/detail.php?SName=Apios%20americana
