WaterThe Lily of the Nile should be watered deeply once a week, allowing the soil to dry out slightly between watering sessions. In the warmer months, this may translate to about one inch of water per week, either through rainfall or manual watering. During the growth season, it's crucial to provide consistent moisture without oversaturating the soil. Cut back on watering in the winter when the plant goes dormant, reducing the amount to half a gallon every other week, preventing the soil from becoming waterlogged.
LightLily of the Nile thrives best in full sun to partial shade. An ideal spot would be where the plant can receive at least six hours of direct sunlight each day. If grown indoors, a south-facing window is a good location, but make sure to protect the plant from harsh midday sun during the peak of summer.
TemperatureLily of the Nile prefers a temperate climate and does well between 60°F and 80°F. It can survive minimum temperatures down to 50°F and maximum temperatures up to about 90°F. However, prolonged exposure to temperatures outside this range, either cold or hot, can damage or stress the plant.
PruningPruning the Lily of the Nile is important for removing spent blooms and encouraging new growth. Deadhead the faded flowers throughout the blooming season and cut back the stems to the base in late fall or early winter after the plant has finished flowering. Every few years, you may also need to divide the clumps to prevent overcrowding and stimulate renewed vigor, ideally in the spring before the growing season begins.
CleaningAs needed
SoilLily of the Nile prefers well-draining soil with a pH of 6.0 to 8.0. A mixture of loam, sand, and compost will ensure good growth. Amending the soil with organic matter improves nutrient availability.
RepottingLily of the Nile should be repotted every 2-4 years, best done in the spring. It enjoys being somewhat root-bound, so only repot when necessary.
Humidity & MistingLily of the Nile thrives in moderate humidity levels, but is quite adaptable and does not require any special humidity considerations for growth.
Suitable locationsIndoor
Place Lily of the Nile in bright, indirect light and room temperature.
Outdoor

Life cycleThe life cycle of the Agapanthus 'Streamline', commonly known as the African Lily, begins with seed germination, which occurs in warm, moist soil conditions. After germination, the seedling develops a root system and foliage leaves, progressing into a vegetative state where the focus is on growth and energy accumulation. As the plant matures, it enters the flowering stage, typically during the summer, producing tall stalks topped with clusters of trumpet-shaped flowers that attract pollinators. After pollination, the flowers give way to seed pods, which mature and eventually release seeds, completing the reproductive cycle. In regions with cold winters, the African Lily enters a dormancy period where growth slows or halts until favorable conditions return in the spring. Throughout its life, the plant will continue to expand by forming new clumps from the base, gradually increasing its size and floral display year after year if conditions are suitable.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagation for the Agapanthus 'Streamline', commonly known as the Lily of the Nile, is by division, which is best done in the spring or early fall. This involves carefully digging up the plant, ensuring a sizeable clump of roots and foliage remains intact for each division. It's recommended that each new section should have at least one fan of leaves and plenty of root to ensure a successful transplant. Using a sharp knife or a spade, the clump is divided into smaller sections, each with its own roots and shoots. These sections are then replanted at the same depth they were growing before, spaced about 18 inches (approximately 45.7 centimeters) apart to give them enough room to grow. After planting, it's essential to water the divisions thoroughly to help establish them in their new locations.
