'Porcelain Blue' is a cultivar offered by Annie's Annuals where in Richmond, California it bloomed spring thru fall. It is said to need mild summer temperatures and consistent moisture. Photos below by M. Gastil-Buhl are of a plant from that source: a close-up of the flower structure, a comparison of color to blue tape, and the shape of the plant. The leaf tips of this cultivar are more rounded and less dentate than the species.
