Iris hybrid (Louisiana)

Louisiana Hybrids
Bulbs and bulblike plants, Perennials


A large and remarkably diverse group of 200 to 300 species, varying in flower color and form, cultural needs, and blooming periods (although the majority flower in spring or early summer). Leaves are swordlike or grasslike. Flowers (fragrant, in many kinds) are showy and complex in structure.

Iris hybrid (Louisiana)

Graceful, flattish blossoms on stems 2–5 ft. tall, are carried above and among leaves that are long, narrow, and unribbed. The range of flower colors and patterns is extensive—nearly the equal of tall beardeds.

Plants thrive in well-watered, rich garden soil as well as at pond margins; soil and water should be neutral to acid. Locate in full sun where summer is cool to mild; choose light afternoon shade where summer heat is intense. Plant in late summer; set rhizomes 1 in. deep, 1 1/2–2 ft. apart. Mulch for winter where the ground freezes.
