Duckfoot Herb, Dew Herb
Asiatic Dayflower is a non-native plant from East and Southeast Asia. Although it is pretty when in bloom, it is considered an invasive weed in much of eastern North America. It is especially difficult to eradicate and can survive applications of glyphosate (Roundup and similar herbicides). Asiatic Dayflower is made into a dark blue dye in Japan, and is used as a traditional medicine in China.
