Description:
Blue Flag is a native iris with attractive sword-shaped, blue-green leaves. Bluish-purple flowers with yellow markings bloom on tall, sturdy stalks, May-June. Blue Flag spreads by rhizomes (underground stems); the rhizomes can sometimes cause minor skin irritation when touched. It will tolerate a couple of inches of shallow standing water. Use in mass plantings in wet areas; good choice for rain gardens, water gardens, or pond borders.
