This Iris grows best in very wet conditions, and is often common in wetlands, where it tolerates submersion. The plant spreads quickly, by both rhizome and seed. While it is primarily an aquatic plant, the rhizomes can survive prolonged dry conditions. The Yellow Iris has been used as a form of water treatment since it has the ability to take up heavy metals through its roots.

The Yellow Flag Iris. It is the only yellow-flowered iris and reaches 28 to 38" in pots and up to 48" in the wild. It may be grown in up to 12" of water.
The Yellow Iris has bold, deep green to gray-green vertical foliage and 4 to 12 brilliant yellow flowers per stem. The number of blooms is directly related to the amount of dampness the iris is grown in and how close each plant is to the next. The blooms may have brown to purplish veining on the petals. Normally blooms from May into June. Planting in clumps produces lush, thick stands, but will also reduce the number of blooms per stem. Seeds germinate freely, so clip off seed heads before fully mature to reduce unwanted spreading. A very hardy plant, the Yellow Iris should be wintered outside in the pond. In northern climates, cut back the dead foliage to just above the water line, southern grown plants may remain green all year. Divide and repot this iris in the fall or after the bloom season. Zones 4-11.
This will grow in boggy water.
