Dietes iridioides

Common Name:
African Iris

Description:
Dietes iridioides is a hardy, clump-forming evergreen perennial known for its elegant, iris-like flowers and strappy green foliage. This versatile plant produces delicate white blooms marked with yellow and pale blue, appearing in flushes from spring through to autumn, often following warm weather or rainfall. Each flower is short-lived but quickly replaced, creating a prolonged display. Well suited to Melbourne conditions, it thrives in full sun to part shade and prefers well-drained soil, though it will tolerate a wide range of soil types and periods of dryness once established. It is also tolerant of coastal exposure, light frost, and urban conditions, making it a reliable, low-maintenance choice. Ideal for mass planting, borders, pathways, and contemporary landscapes, Dietes iridioides adds structure and movement while also being suitable for pots.
