Just about the purest blue in the floral kingdom, and indeed the flowers make a prized blue dye in Japan. These flowers are common weeds in city yards and vacant lots, but old Pa Pitt loves them and loves to photograph them. These were part of a big patch blooming in Beechview in the morning. By the middle of the afternoon, the flowers are withered, so you must look for them early in the day.
For a description of the species, see the Commelina communis reference page.
