Louisiana Iris The Louisiana Iris is perhaps the most magnificent of its species. Although it is adaptable to all climates, the iris is seen growing wild mainly in damp, marshy locations on Louisiana's coastal areas and for perhaps 100 miles inland. This graceful beauty grows to a height of 5 to 6 feet and has a wider color range than any other iris, ranging from pale blue to deep indigo.
