Broadleaf Weed – Dayflower

(Commelina communis)

Dayflower – also known as Asiatic Dayflower and Common Dayflower – is an annual monocot that resembles a dicot. Commelina communis prefers rich, moist soils and commonly occurs along the edges of lawns, gardens, fence rows, buildings and waste areas. Dayflower thrives in most of the southern, eastern and mid-western United States, and can also be found in Washington and Oregon.

Identifying Dayflower -

Dayflower initially grows erect but eventually takes on a creeping or somewhat ascending growth habit. Its stems and leaves are thick and fleshy with the leaves lacking petioles and featuring hairs on the upper and lower surfaces. The leaves also feature parallel running veins often found in monocots. Dayflower also features sheaths at the base of the blade, clasping the stem, and hairs at the base of the blade where the sheath opens.

Blooming from mid-summer to early fall, Dayflower features small blue flowers with three petals. The flowers only last for one day, hence the name “Dayflower.”

Dayflower Control -

In order to be effective, hand-pulling must be undertaken when the weed is small and considerable care must be taken to ensure all the stem fragments have been removed. Relying solely on cultural weed control methods for removing Dayflower typically results in re-establishment of the weed in your lawn.


Scotts LawnService recommends a selective systemic weed control program to fight Dayflower in your lawn, which ensures the herbicide is moved throughout the weed, killing it completely root and all.
