    The Asiatic Dayflower is native to most of East Asia and the Northern parts of Southeast Asia but has been introduced to other areas of the world. It is considered a noxious weed in many areas and has become common in disturbed sites, lawns and other areas of moist soil. The plant can be erect or spreading and has smooth, hairless stems. The flowers are borne from summer through fall on 1" to 2" stalks; blooms have two large bright blue upper petals and one lower pale white petal.
