Silene virginica (fire pink)

Fire pinks are striking spring-flowering plants--their red petals really stand out in the forest at this time of year.  The common name of this species confuses many people as the flowers aren't actually pink, but they are pinked.  This plant belongs to a family (Caryophyllaceae) in which most species have notched petals, as you can see in the photo above.  They look like they were cut with pinking shears (scissors that make a zig-zag cut)...sort of.
