Tantalizing tiny tuff plant ID?
Last fall, I traveled I-65 to Minnesota with my daughter. We stopped just north of the Alabama/Tennessee line at a gas station. Beside it, there was a sloped area that might have been 18 wheeler parking at one time. Growing along the grass/weed line, there was a sedum-looking plant. I pulled a couple, but they did not survive the 6 day trip. They were about 4-6" tall with wiry red stems. The flowers were pink, and covered 5 "fingers" (like a star-fish) that branched out at the top of the stem. The few leaves were tear drop shaped and sized. The area recieved full morning and afternoon sun, but would have been shaded later in the day. The "soil" was sandy clay with a lot of blacktop and gravel mixed in. I have tried several times to research it with no success. Does anyone have an ideal what that very tuff small plant is?
