How to Care for Agapanthus (African Lily) Plants

Agapanthus, also known as African Lily or Lily of the Nile, is a stunning, low-maintenance plant that adds a touch of elegance and color to any garden. Its striking, blue or white flowers bloom atop tall, slender stems, making it a popular choice for garden borders, containers, and mass plantings. This versatile perennial is not only easy to grow but also attracts a variety of wildlife, including birds, butterflies, and hummingbirds. In this article, we’ll explore the best ways to care for Agapanthus, its ideal growing conditions, and how to incorporate it into your garden design.

Main Caring Considerations


Agapanthus requires average watering, meaning it needs to be watered regularly, especially during the growing season. However, it’s important not to overwater, as this can lead to root rot. Ensure the soil is moist but well-drained, and allow the top inch of soil to dry slightly between waterings.

Light Care

These plants thrive in full sun to partial sun exposure. For the best flowering results, provide your Agapanthus with at least 6 hours of direct sunlight per day. If you live in an area with extreme summer heat, some afternoon shade can help protect the plant from scorching.

Soil Care

Agapanthus prefers moist but well-drained soil with a pH level that can be acidic, alkaline, or neutral. It can grow in different soil types, including chalk, clay, loam, and sand. To improve drainage, you can add organic matter such as compost or well-rotted manure to the planting area.

Growing Region

Agapanthus can be grown in USDA hardiness zones 1 through 12, making it a suitable plant for a wide range of climates. In colder climates, it may require winter protection or can be grown in containers and brought indoors during the winter months.

Growth Rate, Height, Size, and Spread

Depending on the variety, Agapanthus can reach heights of 1 to 4 feet (30cm – 120cm) tall and have a spread of 1 to 3 feet (30cm – 90cm). It has a moderate growth rate and will typically reach its full size within 2 to 3 years.

Season and Temperature

Agapanthus blooms during the summer months, with flowers lasting for several weeks. It can tolerate a wide range of temperatures and is hardy in USDA zones 1 through 12. In colder climates, it may require winter protection, such as a thick layer of mulch or being brought indoors if grown in containers.


Pruning is generally not required for Agapanthus, but it can help maintain its shape and encourage more vigorous blooming. After the flowers have faded, you can remove the spent flower stalks to prevent the plant from producing seeds and encourage more blooms in the following year.


Agapanthus produces eye-catching, blue or white flowers that bloom in clusters atop tall, slender stems from mid to late summer. The flowers are long-lasting and make excellent cut flowers for arrangements.


Agapanthus is relatively pest-resistant, but it can occasionally be affected by common garden pests such as slugs, snails, and aphids. Regularly inspect your plants and treat any infestations with appropriate methods, such as hand-picking, using organic pesticides, or introducing beneficial insects to your garden.

Attracts and Tolerance

Agapanthus is a favorite among pollinators, attracting birds, butterflies, and hummingbirds to your garden. It also has a high tolerance for deer, rabbits, drought, and salt, making it a great choice for gardens in coastal areas or with challenging conditions.

Garden Styles

This versatile plant can be incorporated into various garden styles, including city and courtyard gardens, coastal gardens, gravel and rock gardens, and Mediterranean gardens. Its tall, slender stems and striking flowers make it an excellent choice for garden borders, mass plantings, or container gardening.

Companion Plants

Agapanthus pairs well with a variety of plants, including ornamental grasses, lavender, salvia, and echinacea. Choose companion plants with similar growing requirements, such as similar light and water needs, to create a harmonious and visually appealing garden design.
