Summary

Dietes iridioides, commonly known as African Iris, is an evergreen perennial herb native to open woodlands, grasslands, and savannas of Southern and Eastern Africa. It can grow up to 60 cm in height and 30-60 cm in spread, forming dense clumps with a fan-like appearance. The African Iris is characterized by its stiff, sword-shaped leaves and attractive flowers, which are white with yellow and violet markings, and measure 6-8 cm across. The flowers bloom on branched stalks and are quite showy, though each blossom lasts only a few days. After flowering, the plant produces seedpods that can cause the stalks to bend toward the ground, aiding in seed dispersal.

This plant is valued for its drought tolerance and low maintenance requirements, making it a popular choice for water-wise gardens. It is often used in mass plantings, as a ground cover, or in borders. African Iris thrives in full sun to part shade and prefers well-drained soils. While it can tolerate a range of soil types, it performs best in soils with medium to fast drainage. Regular deadheading can encourage more blooms. It is generally pest and disease-free but can be affected by snails and slugs.CC BY-SA 4.0
