Dietes vegeta (D. grandiflora)(D. iridioides)(Moraea iridioides) is a vigorous evergreen with clumps of long, upright, narrow, dark green leaves. Small, Iris-like white flowers with gold markings on the outer petals and three inner petals of violet appear spring-fall in flushes of nearly two-week intervals resulting in the common name of fortnight lily. Drought tolerant in shady gardens, and tolerates coastal conditions. Blooms best with regular watering. Attractive in mass plantings, in patio containers, or as a solitary accent plant.
How large does it grow and what is its growth habit?
It typically grows about 2 to 4 feet tall and spreads about 2 to 3 feet wide, with fan-like leaves and flower stalks rising above the foliage.
What light and soil/site conditions does it prefer?
Preferably full sun to part-shade; best in well-drained soil (can tolerate sandy or modest soils) and benefits from regular moisture while establishing.
What about watering, maintenance and general care requirements?
Water regularly when first planted; once established the plant is drought-tolerant. Avoid overly rich or water-logged soils. Divide clumps every few years and remove old foliage for a tidy appearance.
What pests, diseases or caution notes apply?
Generally low-maintenance. However, avoid poorly drained sites to prevent root/crown rot, and note that parts may be poisonous if ingested.
