Identification:
Perennial herb; flowers May to October. Grows 1to 2 feet tall. Stems and leaves fleshy; overall plant is coarsely hairy. Basal leaves are narrowly oblong; mid leaves are progressively smaller up the stem, and the upper leaves are sessile (no petiole) or clasping. Blue to purple flowers with white throats. Petals are five equal lobes, forming an uncurved tube. Flowers found in coiled clusters at the end of stems. As the flowers open, coils unfold. Fruit is a four-chambered nutlet; each nutlet contains one seed.
Impacts:
This plant invades alfalfa fields, pastures, pine forests, rangeland, riparian and waste areas. The fleshy stalks can cause hay bales to mold. Large, very dense stands can occur, offering strong competition to native plant communities.
