Iris ensata JAPANESE IRIS Prefer a moist to a very moist spot in fertile soil. They have large flowers and make fine, leafy clumps. One of the few U.S. native Iris, Iris cristata DWARF CRESTED IRIS, native to Eastern U.S., is an extremely desirable iris for its shade tolerance. Likes neutral humus rich soil, moist and well drained. Better on a slope than in flat or poorly drained areas. Splendid ground cover in shade, good in rock gardens, edging and borders. Iris germanica BEARDED IRIS, need free draining soil, particularly in the winter. Grows well in fertile loam with average moisture. Beautiful, intricate and complex flowers in a rainbow of colors with green sword shaped leaves. Should be planted with 1/3 to 1/2 of the horizontal rhizomes exposed. Iris pseudacorus YELLOW FLAG grow well in shallow water or water's edge, but will also grow well in the border in moist fertile soil. Leaves are green, coarse, luxuriant, and sword shaped. Iris sibirica SIBERIAN IRIS will grow best in soils that retain moisture, but tolerant of a wide range of soils. Leaves are light green, grassy and sword shaped. I. ensata and I. pseudacorus are best with constant moisture and are at home in or near water, but this is not necessary. Iris versicolor BLUE FLAG Native to Eastern U.S. wetland, this plant is suited to boggy areas and does well in borders with good amounts of humus and moisture. Vigorous with 1/2 to 1 in. wide gray green leaves growing upwards with an arch. Flower stalks reach above foliage and branch, each branch with two or three flowers, yellow blotched and purple veined, paler on top. Good cut flower. Best in sun, tolerating shade.
