Red-Whisker Clammyweed (Polanisia dodecandra)

Western Spiderwort (Tradescantia occidentalis)

Western spiderworts are low-lying plants with three large purple petals. Dayflowers are similar (they're in the same family), so be careful not to confuse the two.  One thing to look for is the western spiderwort's hairy stamens.
