Lower Rio Grande Valley Flowers
Trailing Windmills (Allionia incarnata) are one of two Allionia species in the Four o'clock family (Nyctaginaceae), a mostly tropical plant family.
They are native perennial herbs that grow in the Southwest, from California to Texas.
The notched pink petals are a good field identification clue.
