Yellow Flag Iris / Water Iris - Iris pseudacorus - 30 seeds

Yellow flag iris, Iris pseudacorus, is a vigorous water iris, typically found growing at the edges of large, sunny ponds. It bears large clumps of green leaves from which elegant, yellow flowers appear in late-spring.
Iris pseudacorus is ideal for wildlife gardens, and looks particularly good if planted in naturalised drifts among other moisture-loving plants. It also associates well with dark blue flowered plants. If you don't have room for a pond  garden, try growing it in a large container filled with water. Divide rhizomes every three to five years to keep it under control.
