Orthrosanthus

Morning Flag, Morning Iris
Iridaceae
Evergreen, Perennials, Flowers

These Sisyrinchium relatives have dark green, grasslike leaves arising from short, woody rhizomes. Showy blooms of blue, lavender, or white open in succession on slim, erect stems in summer. Individual flowers look their best in the morning, then fade as the day progresses. Wonderful plants for sunny slopes, rock gardens, and containers. Tolerate poor, sandy soils but bloom better in fertile, well-drained soil.
