Agapanthus orientalis: Agapanthus, African Lily, Lily of the Nile1

Edward F. Gilman, Ryan W. Klein, and Gail Hansen2


Clusters of large, blue, funnel-shaped flowers appear atop long stalks in summer and early fall, rising above the coarse, strap-like, green leaves. Flowers make a wonderful display in mass plantings. They can also be used as accents in a small garden or by the patio.

Use and Management

Growing in full sun or partial shade, Agapanthus is usually left undisturbed for several years and will form a large clump, making an attractive groundcover or accent plant. Agapanthus prefers moist, organic soil conditions but can endure drought once established. Plant about 18 to 24 inches apart for a thick groundcover effect.

Available cultivars include: 'Albus,' white flowers; 'Flore Pleno,' double flowers; 'Variegatus,' with striped leaves; and 'Nanus,' a dwarf, compact form.

Propagation is by division or seed.

Disease-resistant selections are available for humid climates.

Problems include chewing insects, maggots, and borers.

Design Considerations

The strap-like leaves and large blue flowers of the agapanthus make it perfect for highly visible spaces in the landscape. Use with plants that are softer with small foliage and mounding or spreading forms. Dark green and/or burgundy foliage in the companion plants will highlight the clusters of blue flowers and soft green of the leaves. New agapanthus cultivars also have white, dark blue, and violet-blue flowers. When pairing with other flowering plants use white, and warm colors such as pinks and corals and soft yellows and light orange with the blue-flowered agapanthus. The white-flowered variety can be used with any other color to brighten the space.

Pests and Diseases

Botrytis can devastate a planting, especially in humid climates in the eastern US. Try the disease-resistant selections in the East.
