Description
A blue dye extracted from the petals of the Commelina communis lily plant native to Asia. Dayflower is a herbaceous annual plant that sprawls along the ground like a vine, often rooting at the nodes. The flowers bloom only for a day, emerging one at a time. The plant is considered invasive in the United States and it is resistant to many herbicides. The blue colorant in the dayflower blue dye is primarily commelinin.
