Four o'clock
(a.k.a. trailing windmills, guapile)

Allionia incarnata var. incarnata's bright pink blossoms and distinctive foliage with wavy leaf margins.

Four o'clock is a prostrate perennial herb which is glandularly pubescent. The flowers are pink and notched. The leaves are wedge shaped. The three flowers of four o'clock in each whorl all flower at the same time and are very close together, giving the illusion of one large completely symmetrical flower. Actually, the three flowers are each individually bilaterally symmetrical. The complicated fruit of four o'clock has two incurved wings that are frequently triangularly toothed, and it has two rows of glands on its surface. Four o'clock is found in low, dry, rocky areas.
