Geisha Obi is wine-red with white rays and styles. These iris are native to the Gulf Coast. The blooms are very wide-petaled and brightly colored. Louisiana iris need at least a half day of sun, a neutral or acidic soil, and plenty of fertilizer and water. Sandy or heavy clay soils should be amended with organic matter.
New growth appears in fall, and in mild winters the foliage remains erect and green.
Louisiana iris rhizomes should be planted deeper than other iris, at least 1 inch under the soil, then mulched with 2 to 4 inches of compost. Cajun Sunrise features brownish-red petals edged in yellow. Delta Star is a dark purple cartwheel-shaped flower with narrow yellow signals. It grows especially well in water. Dixie Deb is tall with medium-sized yellow blooms.
