Quick Overview:

Wow Factor’s flowers are pale yellow with brownish veining. Foliage is green and swordlike. More mild-mannered than invasive Yellow Flag Iris, it’s the perfect plant for adding some bright color to pond margins.


Louisiana irises prefer a rich, acidic soil with plenty of moisture. If summers are dry, provide supplemental water to encourage blooming or move to a wet site. Never let it dry out. Plant in full sun to partial afternoon shade (in hot climates and desert southwest). Benefits by heavy fertilization. Louisiana iris have rhizomes which are thick, fleshy stems that grow underground. To plant rhizomes, dig a shallow hole just below the soil surface. Place rhizomes with the growing tip pointed up and roots pointed down. Make sure the growing tip is oriented in the direction where you want it to go since the fan will grow from that point. If planting several rhizomes, space approximately one foot apart. Primarily propagated through division. Dig and divide only when plants have less vigorous flowering. Don’t let it dry out during transplanting. Can be divided in spring or fall. May have problems with iris borer, slugs or snails.
