Comments

This is a pretty plant while in bloom, and it has neat foliage. Distinguishing different species of Blue-Eyed grass can be rather difficult. Stout Blue-Eyed Grass has leaves that are slightly broader than most species of Blue-Eyed Grass, and it occasionally produces flowers from long secondary stalks, as shown in the lower photograph. The flowers are consistently deep blue-violet, rather than pale blue or white. Only a single spathe with an umbel of flowers is produced from a flowering stalk, while Sisyrinchium albidum (White Blue-Eyed Grass) produces two spathes. If you find a Blue-Eyed Grass with blue-violet flowers in a wooded area, this is the species that you are probably looking at. Other Sisyrinchium spp. in Illinois prefer sunnier habitats in either prairies or moist sandy meadows. Return
