Narrowleaf Blue-eyed Grass (Sisyrinchium augustifolium)

Narrowleaf Blue-eyed Grass (Sisyrinchium augustifolium) 

Narrowleaf Blue-eyed Grass (Sisyrinchium augustifolium), sometimes called Pointed Blue-eyed Grass, is of the Iris Family (Iridaceae) and order Liliales (Lilies).  The small, blue flowers are near the top of a leaf-like twisted stalk as shown in the photograph above. The flowers are about ½ inch (1.3 centimeters) in diameter and have three petals and three sepals that resemble the petals. The center of the flower contains bright yellow stamen and pistils giving the center its characteristic color. It flowers from May through July. This plant was photographed on the eastern shore of French Hill Pond.

The leaves are linear, about four to 20 inches (10 to 50 centimeters) long, very narrow and resemble grass, whence the name. However, this plant is an Iris.

The fruit is a black seed.

The root system is a small bulb with shallow roots.

This plant helps filter water runoff. It makes a small contribution to stabilizing soil. Although nontoxic, it has little value as food for grazing animals.
