Beardless iris can be used in moist soils and near water. They grow in full sun but prefer partial shade and are best planted in late summer or early autumn. Soil moisture is important in the spring when the plants are growing. Several types of beardless iris are listed.

Iris forrestii This iris grows to 1 and a half feet and has yellow flowers veined with brownish purple. It needs a rich soil with lots of humus and may be more difficult to grow than I. siberica.

Iris pseudacorus--Yellow Flag, Water Flag. The flowers are yellow and produced in May or June.

Iris siberica--Siberian Iris It produces light blue flowers and grows 2 to 3 feet tall. Varieties are available producing flowers of some color other than light blue.

Iris spuria--Seashore Iris This iris grows 2 to 4 feet tall and dislikes transplanting.

Iris versicolor--Blue Flag Blue flag grows 2 feet tall and produces purplish flowers.
