This short-lived long blooming herbaceous perennial is native to western North America where it is found on ridges and dry slopes as well as in mountain meadows and grasslands. It is upright, clump-forming, and has an abundance of blue, lavender, or white flowers from late spring through summer. Each cup-shaped flower is about 1 1/2″ across, has five petals with prominent veining and last for just a day, opening fully only on sunny days. The leaves are blue-green and needle-like giving the whole plant a delicate wispy look. Although it readily reseeds, plants do not transplant well. Suitable for beds and borders as well as wildflower gardens.
