WaterLily of the Nile, commonly known as Agapanthus 'Donau', should be watered regularly to keep the soil moist but not waterlogged. During the growing season in spring and summer, it typically requires watering once a week with about one gallon of water per plant. Reduce the frequency to every other week in fall and once a month in winter, depending on rainfall and temperature. Ensure proper drainage to prevent root rot, and water less often if the plant is in a cooler, shadier spot. During hot, dry spells, you may need to increase watering frequency.
LightLily of the Nile thrives in full sun to partial shade. For optimal growth, place the plant in a location where it receives at least six hours of direct sunlight daily. If you are growing the plant indoors, choose a bright, sunny window or supplement with grow lights if natural light is insufficient.
TemperatureLily of the Nile prefers moderate temperatures and grows best when daytime temperatures are between 70°F and 80°F. It can survive minimum temperatures down to 50°F. However, it is not frost-tolerant, and temperatures below freezing can damage or kill the plant. If you live in an area with cold winters, it's best to grow the plant in a container and bring it indoors or provide protection when temperatures drop.
PruningPrune Lily of the Nile after flowering by removing spent flower stalks to encourage new growth and maintain the plant's appearance. During late winter or early spring, cut away any damaged or dead foliage. Pruning is typically done annually, and it is also a good time to divide the rhizomes if the plant has become too crowded.
CleaningAs needed
SoilThe best soil mix for Agapanthus, commonly known as African Lily, should be well-draining and fertile, enriched with compost or peat moss. An ideal pH range for this plant is between 6.0 and 8.0. A mixture of two parts loam to one part perlite or sand and one part peat or compost will create an optimal growing environment.
RepottingAfrican Lilies should be repotted every two to four years or when they become root-bound. This is a crucial step to ensure the plant has enough room to grow and to refresh the nutrient content of the soil.
Humidity & MistingAfrican Lilies prefer moderate humidity levels but are quite adaptable and can tolerate conditions typical of most homes. There is no need for any special humidity considerations beyond normal indoor levels.
Suitable locationsIndoor
Ensure bright light, well-draining soil, and occasional watering for indoor African Lilies.
Outdoor
Plant in sunny spot, guard from frost, and use well-draining soil for African Lilies.

Life cycleThe African Lily 'Donau' begins its life cycle as a seed which, when sown in fertile, well-draining soil and given appropriate warmth and light, germinates to produce a small seedling. As the seedling grows, it develops into a clump-forming perennial, characterized by strap-shaped, glossy green leaves that form at the base of the plant. Over time, typically in the summer months, it produces tall, erect stems that bear rounded clusters of funnel-shaped, blue to violet flowers. After flowering, if pollination occurs, the flowers may develop into seed capsules which, upon maturity, release seeds to enable the cycle of reproduction. When growing conditions become less favorable, especially in cooler climates, the African Lily may enter a dormancy period where growth slows down or stops and the foliage may die back to conserve energy. With the return of favorable conditions, the plant resumes growth, completing its perennial cycle.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagating the Agapanthus 'Donau', commonly known as Lily of the Nile, is by division. This process is best performed in the spring or early summer, when the plant is coming out of its dormant period and beginning to grow actively. To propagate by division, carefully lift the entire plant from the ground using a spade, making sure to keep the root ball intact. Gently separate the clumps into smaller sections, each with a portion of the roots and at least one or two growing points or shoots. Replant these divisions immediately, ensuring they are placed at the same depth they were growing at previously. It's important to water the newly planted divisions thoroughly to help establish them. This method allows the plant to recover quickly and continue growing, producing blooms within the following seasons.
