Louisiana State Wild Flower

Louisiana Iris

(Giganticaerulea)

Adopted in 1990

The Louisiana Iris (Giganticaerulea) is perhaps the most magnificent of its species. Although it is adaptable to all climates, it is seen growing wild mainly in damp, marshy locations in Louisiana's coastal areas and for perhaps 100 miles inland. This graceful beauty grows to a height of 5 or 6 feet and has a wider color range than any other iris, from pale blue to deep indigo. It became our official wildflower in 1990.

Louisiana Legislature Archives
§154.1.  State wildflower
There shall be an official state wildflower.  The official state wildflower shall be the Louisiana iris (Giganticaerulea).  Its use on official documents of the state and with the insignia of the state is hereby authorized.

Perhaps the most magnificent of its species. Although it is adaptable to all climates, it is seen growing wild mainly in damp, marshy locations in Louisiana's coastal areas and for perhaps 100 miles inland.

Mature plant size varies from 1 to 6 feet and flower sizes from 3 to 7 inches across. Flowers occur in March and April. Because all the primary colors are inherent in the various species that contributed to this group, there is no limit to the color range. The Louisianas, for example, include the purest form of red of any iris.
