Care essentials
Light
Giant Apostle's Iris grows in full sun to part shade; it tolerates more sun than commonly assumed when soil stays consistently moist. In NE Florida, a spot with morning sun and afternoon shade in summer prevents leaf scorch.
Water
Prefers consistently moist, moisture-rich soil; water regularly, especially during dry spells. Established clumps in NE Florida handle brief drought but perform best with even moisture and mulched root zones.
Soil & Fertilizer
Plant in moist, fertile loamy or sandy soil amended with compost. Fertilize lightly in spring and fall with a balanced slow-release fertilizer to support vigorous clumping growth in NE Florida's nutrient-poor sandy soils.
