Butterfly African Iris (Dietes grandiflora) is a striking perennial with tall, upright spikes that produce large white blossoms adorned with yellow and purple centers. Blooming from spring through fall, this iris variety brings long-lasting color and elegance to the garden. Its graceful, sword-like foliage provides year-round interest, making it ideal for borders, mixed perennial beds, mass plantings, or containers. The Butterfly African Iris also makes an excellent patio plant and can be overwintered indoors in colder climates.

Native to South Africa, this iris is valued for its hardiness, repeat flowering, and versatility in both formal and naturalized garden settings. Its blooms are attractive to pollinators, adding ecological benefits along with beauty to your landscape.

Butterfly African Iris Care

Plant in organically enriched, well-drained soil for the best performance. Water regularly until established, then reduce to occasional deep watering as this plant is more drought-tolerant than many other iris varieties. Apply a layer of organic mulch in colder regions if extended freezes are expected. This is a vigorous grower and can be divided every few years to refresh growth and expand plantings.

Butterfly African Iris Growth & Spacing

Mature plants reach 2 to 4 feet tall with a spread of about 2 to 3 feet. For perennial borders or mass plantings, space 3 feet apart, center to center. In containers, choose a large pot to allow for root development and long-term growth.
