Dayflowers have intensely blue flowers (from which the Japanese make an intensely blue dye) that open from a crescent-shaped spathe and are gone by the middle of the afternoon. Usually only one flower opens in the spathe at a time, but once in a while we see two or even three together.

For a description of the species, see the Commelina communis reference page.

A common weed imported from Asia, probably for its intensely blue flowers. These plants were growing by a wooden fence in Beechview.
