Commelina diffusa, commonly known as the climbing dayflower, is an annual or perennial herb native to tropical and subtropical regions of Africa, Asia and parts of the Pacific. It typically grows up to 1.5 feet (45 centimeters) in height and spreads diffusely, with stems that root at the nodes and form dense mats. The plant features bright blue, three-petaled flowers that bloom in the morning and close by afternoon, with a flowering season that lasts from late spring to early fall. The flowers are relatively showy and attract pollinators such as bees.

The climbing dayflower is valued for its rapid growth and attractive flowers, making it suitable for ground cover in tropical and subtropical gardens. It thrives in moist, well-drained soils and can tolerate a range of light conditions from full sun to partial shade. However, it requires consistent moisture and may not be drought-tolerant. In cultivation, it can be used to stabilize soil in wet areas or as a filler in garden beds. Due to its invasive potential, it should be managed carefully to prevent unwanted spread.CC BY-SA 4.0
