This is an excellent hybrid of blue-eyed grass, an iris relative that goes underused in the garden. Mound of grass-like foliage are contrasted by bright blue to violet star-shaped flowers with a yellow eye in early summer. A great plant for relatively dry, sunny or partially shaded areas or a rock garden. Most hybrids and the species S. montanum are hardy to zone 2 or 3; S. idahoense is more tender.
