How to Plant Louisiana Iris


Named by James Audubon himself, Louisiana iris describes a series (Hexagonae) of beardless iris that contains five species. These irises are adaptable and grow in a wide variety of conditions, from the water to the garden. The most important element when growing the Louisiana iris is, in fact, water. While it will thrive planted directly in a pond or other water source, deep watering twice a week is recommended for those planted in pots or in the garden. Plant the Louisiana iris from mid-August to mid-September.

Step 1

Place the Louisiana iris bulb in a glass of water until you are ready to plant. Choose a location in full sun in which to plant the Louisiana iris.

Step 2

Add a 3-inch layer of rotted manure and a 2-inch layer of peat moss to the planting bed and til the materials to a depth of 6 inches. Add 8-8-8 fertilizer (10 lbs. per 100 square feet of flower bed) and mix that in to the same depth.

Step 3

Plant the iris bulbs so that the top of their rhizomes are just above the soil level, 12 inches apart, in a triangular pattern.

Step 4

Water the iris bed to a depth of 6 inches and keep the soil moist at all times.
