Native prairie wildlfower, pretty common to find these plants growing wild out on the prairie. Is not really a 'grass', rather is a member of the Iris family. Quite an adaptable plant - have seen this growing in shady moist conditions on the edge of woods, and in very dry, hot, sunny locations in the Grasslands National Park. Grows 4" - 12" in height. Will grow in full sun or part-shade. Space 12" apart. Hardy in zones 2-9. Blooms in May and June! Excellent for the front of the border or perhaps planted along a path.
