Asian Dayflower
Commelina communis
Commelinaceae (Spiderwort) Family

Asian Dayflower is also known as Blue Dayflower and Asiatic Dayflower.

Plant is an upright to prostrate, mostly smooth, annual that roots at the nodes or stems. Its preferred habitat is woods, waste areas, yards and at roadside. Distribution is throughout the Escambia region.

The leaves are alternate on the stem; no teeth and no lobes. Leaf shape is oval with base portion clasping the stem.

Flowers are at the tip of the stem appearing either solitary or in clusters. Each flower is supported by a spathe; divided into two parts with one being the image of the other; three sepals, three petals (two blue, one smaller white). Flowers are bisexual in nature. Flowers occur in the spring and summer.

A related day flower, C. virginica (discussed in autumn wildflower), is similar but is hairy and has longer lance-like leaves. The species name “Commelina” refers to the Dutch botanists who first discovered and described the plant.

Handling the plant may cause skin irritation or allergic reaction

Legend has it that three brothers worked closely together in botanical studies. Two brothers distinguished themselves in the profession and were honored with the species name. A third brother who contributed little to the science was awarded the more insignificant white petal. The name “Day Flower” refers to the fact that the blossom remains on the stem for about 24 hours.
