PLUMBAGINACEAE, The Leadwort family
Also called Leadwort, this ground cover has bright blue flowers in summer and autumn. It is deciduous, but the fall color is scarlet to burgundy. It grows 6-10 inches tall and slowly spreads to form masses. Dwarf plumbago can also look great in containers. I’ve been using it so much lately because there are few plants with a lovely blue in autumn, and many of the color themes in my designs have rich reds and purples that clash with lavenders that have any pink in them. The plant has both deep red shades and the strong cobalt that holds its own.
