Japanese Iris

Japanese iris thrives in full sun to part sun in NE Florida. Provide afternoon shade during the hottest months to reduce heat stress; consistent soil moisture is essential whenever grown in full sun.

Requires consistently high moisture and tolerates standing water up to 6 inches deep. In NE Florida, plant at pond edges or in reliably moist beds; do not allow soil to dry out, especially during the summer bloom period.

Plant in humus-rich, acidic, moist to wet soil. Fertilize with an acid-forming fertilizer in early spring before growth begins. Divide clumps every 3–4 years to maintain vigor in NE Florida's warm climate.
