American blue-eyed-grass forms neat, grass-like clumps with delicate blue flowers that bloom in late spring and early summer. Despite its name, it's actually a member of the iris family and creates an orderly, low-maintenance groundcover. The small star-shaped flowers add subtle color without being overwhelming.
