The Louisiana Iris Group

Louisiana irises are a unique American hybrid race, combining five native southeastern U.S. species. They offer: an incredible color range (including true reds, coppers, yellows, blues, purples, browns), vigorous growth in wet conditions, evergreen foliage in mild climates, and late spring bloom (often after TBs). 'Easter Tide' (1979) comes from a golden age of Louisiana breeding.

Garden Culture

Louisiana irises want: Water: Consistent moisture; thrive in bog gardens, pond margins, irrigated beds. Sun: Full sun (6+ hours) for best bloom. Soil: Rich, acidic to neutral, high organic matter. Planting: Rhizomes 2–3 inches deep (deeper than bearded). Hardiness: Zones 6–9 (mulch in 6). Fertilizer: Heavy feeders—regular fertilizer during growth. 'Easter Tide' likely displays the group's vigor and color range.
