African Iris – An Elegant, Easy-Care Landscape Favorite
Add lasting greenery and beautiful white blooms with touches of yellow and blue. Perfect for walkways, garden beds, and Southwest Florida landscapes.
African Iris, also known as Fortnight Lily, is an evergreen perennial with upright, narrow green leaves and white flowers marked with yellow and blue. It grows in clumps and provides consistent foliage height throughout the year in Southwest Florida. Its manageable size makes it useful for walkway borders, foundation beds, and larger landscape plantings. This plant typically grows 2–4 feet tall and 2–3 feet wide, depending on the variety and growing conditions. It forms clumps that gradually expand, making it suitable for borders and grouped plantings without the height of larger shrubs.
This plant grows in full sun to partial shade and adapts to Southwest Florida's sandy soils. It performs best with good drainage but can also tolerate occasional periods of wet soil. Its moderate growth rate and limited pruning needs make it useful for landscapes requiring a consistent planting height. Older leaves and finished flower stalks can be removed as needed.
For borders and mass plantings, space African Iris approximately 2–3 feet apart, depending on the size of the plants and how quickly continuous coverage is desired. African Iris requires regular watering during establishment. Once established, it tolerates short dry periods, although consistent moisture helps support healthy foliage and repeated flowering.
