Iris planifolia, commonly known as the flat-leaved iris, is a bulbous geophyte native to the Mediterranean region. It belongs to the family Iridaceae and the genus Iris. This plant thrives in subtropical climates and is known for its striking blue or violet flowers. It undergoes a dormancy period during the summer months.
Iris planifolia requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and moderate humidity levels. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. This plant is best suited for outdoor growth in subtropical climates.

伝搬
Propagate Iris planifolia by dividing the bulbs during the dormant period. Carefully separate the bulbs and replant them in well-draining soil. Ensure each bulb has enough space to grow.
剪定
Pruning is not typically required for Iris planifolia. Remove any dead or damaged leaves to maintain the plant's appearance and health.
