Asiatic dayflower Overview
Commelina communis is a clumping, perennial species commonly known by the name Asiatic dayflower because of their short flower lifespan. They are often grown as annuals in temperate regions and are considered annual weeds, they are also considered annual or perennial weeds in tropical locations. They produce flowers one at a time and these last for a short time. The flowers are small, 3-petalled, blue, saucer-shaped and encased in a spathe-like modified leaf structure. Flower structure is only symmetrical in one plane, with the petals differing in size and shape across the flower, with two larger top petals and a reduced lower petal.
