Florida’s natural environment is filled with beautiful flowers, shrubs, and trees. Take advantage of Florida’s warm weather by enhancing your lawn with plants that thrive in this climate. Among the many options, African lilies, also known as Lily of the Nile (Agapanthus), are an excellent choice. These perennial herbaceous plants from the amaryllis family are common ornamentals in warm climates and are grown for their large, spherical flower clusters.
Agapanthus heralds spring in South Florida with blue flowers that sway above handsome, strappy leaves in a glossy deep green. The spring flowers that pop up in a ball-shaped cluster add a lovely and unusual touch of blue to the garden.
Characteristics of Agapanthus
African lilies (Agapanthus africanus and hybrids) are blue-flowered perennials that grow from rhizomes, which are fleshy roots. Each rhizome sends up several shoots, and over time, a one-gallon plant of a vigorous cultivar like ‘Blue Storm’ can form a clump 2.5 feet wide.
The flowers are funnel-shaped and typically purple, blue, or white. Individual plants can reach up to 4 feet tall and 2 feet wide, but dwarf forms are available.
Ideal Growing Conditions in Florida
Agapanthus grows best in USDA hardiness zones 9-11. It performs well in partial shade or full sun, drought, and even sandy loam soil. It will tolerate occasionally wet, slightly alkaline, acidic soil, and clay soil.

Sunlight
Gardeners in Florida should plant their agapanthus in full sun for the best blooms. It takes full sun in the northern part of the state, but in South Florida, part sun to part shade is ideal.
Soil
Agapanthus is well-suited for loamy or clay soils. Add composted organic matter to clay soil before planting.
Water
Water on a regular basis but allow time between waterings for the soil to dry out. Make sure the area drains well, as this plant doesn't like wet conditions. Light irrigation between spring and fall is ideal. In most of Florida, agapanthus is dormant during the winter months, so avoid watering during this period.
Fertilizing
To bloom regularly, fertilize agapanthus twice a year, either after blooming, in early fall (September in the Upstate, October in the Lowcountry), or in early spring (early March in the Lowcountry and April Upstate). Fertilize in spring and fall with a good granular fertilizer. Add composted cow manure to the hole when you plant.
Planting and Spacing
Plant about 2 to 2-1/2 feet apart. Come out from the house and in from walks and drives about 2 feet. When planting, space individuals 18-24 inches apart.

Maintenance Tips
Trimming is unnecessary, though after flowering, it's a good idea to cut the dead flower stalks back near to the ground.
Agapanthus may take two to three years to establish and reach peak bloom.
Other factors that boost blooming are improved soil and high “stand” density (agapanthus blooms best in dense, undisturbed clumps of plants called stands).
It’s time to divide and transplant lily of the Nile when clumps don’t flower even after fertilizing. Since agapanthus flowers in June (Lowcountry) to July (Upstate), early fall is the best time to disturb clumps.

The 'clumps' are easily divided by digging up the rhizomes, separating them, and creating new individual plants that multiply more rhizomes.
To move a portion of a clump, dig as large a root ball as possible. Don’t cut off bare roots that stick out beyond the root ball; carry them along to the new site.
Potential Problems
Although insect pests are not usually a major concern, gardeners occasionally find some chewing and boring on the leaves.
As for disease, botrytis fungus can be damaging to plantings of agapanthus.
Versatile Uses in Landscaping
Agapanthus is a versatile plant that can be used as an accent, border, foundation plant beneath low windows, or even as a groundcover. It is especially striking when grown en masse, transforming a landscape with its blossoms.
This plant works in a tropical setting or formal landscape, creating a cottage garden or English garden look.
Popular Cultivars
Available cultivars include:
- ‘Albus’: with white flowers
- ‘Flore Pleno’: double flowers
