Stout Blue-Eyed Grass (Sisyrinchium angustifolium)
If you have a well drained site in your yard that receives lots of sun, these are the plants for you. This beautiful plant blooms a star-shaped flower that opens in the morning to reveal six pale blueish-purple petals and a yellow center, and then will close in the afternoon or evening. Despite their common name, the Blue-eyed Grasses are not grasses at all but rather members of the Iris family. They handle competition quite well and readily spread via underground rhizomes.
