Description

This lovely, delicate iris is native to the United States and Canada, from the east coast to the middle states as far west as Texas. It can reach 2 to 2.5 feet with light blue to violet flowers borne on naked stems in late spring.  The falls are marked with white and can be crested with yellow frill.  The leaves which are strap-like and have a pronounced midrib in the center are not as upright; they may lay over or fall into the water.

It does best grown in very wet, humusy to sandy soil and in boggy acidic areas in full sun.  It should not be permitted to dry out in the growing season and is natural in wild areas with standing water.  These iris may be left in water over winter and can be used in pond borders of up to 6 inches deep.  It will tolerate light shade in the warmer regions of its range. Southern Flag Iris spreads slowly by rhizomes which can be divided for propagation as clumps form.

This iris is deer resistant and not susceptible to disease.
