This perennial herb is variable in morphology, but usually forms a tight mat or loose clump on the ground. The short stems emerge from a woody taproot and caudex unit and the plant form is no more than tall. The abundant tiny, sharp-pointed leaves are oppositely arranged and barely exceed long. The herbage is hairy in texture, the hairs short to long, woolly to cobwebby. The appearance of the plant is almost mosslike until blooming.USGS Northern Prairie Wildlife Research Center The inflorescence is a solitary flower in shades of white, pink, or blue. It has a tubular throat about long spreading into a flat five-lobed corolla.
