Blue-eyed Grass is a perennial under 1 foot high. It has small star-shaped flowers with soft blue petals and yellow centers on long, narrow leaves resembling grass. In the wild, the plants grow in open woody areas and clumps are small. When grown without competition and given better soil and more moisture, they thrive. This is a good wildflower alternative to Monkey Grass. Several plants can spread to form a border providing pretty blue flowers from March into June. Grow in full sun to partial shade.

I have not had good luck with this plant in my PNW garden. It may be that my soil is too wet - it likes damp but well draining soil. I have also read that it needs to be divided every couple years to maintain vigor. Pretty little plant when it blooms, so worth a try.
