(Stiff Blue Eyed Grass)


Family: Iridaceae

Sisyrinchium demissum looks very much like a grass until it flowers. It forms clumps with erect stems. The flowers have 6 tepals (petals and sepals that look alike), and are blue purple with yellow centers. The tepals are veined with dark purple. The leaves look like grass blades. The fruit is a 10-15mm ovoid capsule. Sisyrinchium demissum is found in upper elevation meadows.
