Detailed Information

Flower: Flower shape: 6-petals Cluster type: raceme

[photo of flowers] Flowers are ½ to ¾ inch across, pale blue to white with 6 tepals (3 petals and 3 sepals all similar), yellow at the base, with a column of yellow-tipped stamens protruding from the center. Tepals are mostly rounded at the tip with a small, needle-like projection at the very tip. A few flowers are clustered at the top of a stem, the flower stalks enclosed within 2 leaf-like bracts (spathe). The outer spathe is 1 to 2 inches long and about twice as long as the inner spathe. The edges of the outer spathe are typically separate all the way to the base. The spathe color is green to purplish brown.

Leaves and stem: Leaf attachment: basal Leaf type: simple

[photo of stem] Leaves are narrow, toothless, grass-like blades in a basal tuft, each 3 to 10 inches long, or about as long as the flower stems. The flower stems are distinctly winged, about 1/8 inch wide, and smooth along the edges. One or more stems arise from the base.

Fruit: Fruit type: capsule/pod

[photo of fruit] Fruit is a light to dark brown, globe-like capsule, 1/8 to 1/6 inch in diameter.

Notes:

Prairie Blue-eyed Grass can be distinguished from the other Sisyrinchium species in Minnesota primarily by its pale flowers, and dry, sandy habitat.

Chicory flowers last just a few hours, then a new bud opens each day. This is not common knowledge, most believing the flower closes at night to open again the next day. Not true. Does the Blue Eyed flower do the same? Yet not mentioned in the descriptions. We have our share and they are a staple.

Found this today in my small prairie. Just showed up after 5 years without planting it. Very nice surprise.

Several patches are in bloom on 5/6/2017 on the s-facing remnant prairie slope here. This is a larger amount blooming than I have ever noticed before.
