Allionia incarnata, commonly known as trailing windmills or trailing four o'clock, is widespread in the Western Hemisphere. It has unusual blooms, which consist of three separate flowers appearing to be a single flower.

The plants are finely pubescent annuals or short-lived perennials, with trailing, recumbent stems up to one meter in length, often threading through other vegetation. The leaves range from oval to oblong, under 4 cm long. The inflorescences are axillary, consisting of three flowers with petals varying in color from red to purple, symmetrically arranged, and superficially appearing to be a single flower 3–15 mm across. The individual flowers are bisexual and bilaterally symmetric with a distinct oblique funnel. The 5–7 stamens may be somewhat exserted, along with the style. The fruits have five ribs.

The range of Allionia incarnata includes North America, the West Indies, Central America.  Carl Linnaeus named the genus after Italian botanist Carlo Allioni (1725–1804).
