African Lily Agapanthus caulescens subsp. angustifolius
ABOUT
Agapanthus caulescens subsp. angustifolius, commonly known as the Narrow-leaved Agapanthus, is a visually striking plant primarily recognized for its lush foliage and captivating floral displays. The plant forms a clump of long, slender leaves that are deep green in color. These leaves provide an appealing backdrop throughout the growing season. The most distinguishing feature of the Narrow-leaved Agapanthus is its stunning flowers. These blossoms are borne on tall, sturdy stalks that rise prominently above the foliage. The flowers are arranged in a large, rounded cluster known as an umbel, which is akin to a globe of star-shaped blooms that create a fireworks-like display. Each individual flower is funnel-shaped, drawing attention with its delicate structure and often appearing in a beautiful shade of blue or purple. These blossoms can also come in hues of white or pale pink, depending on the variety. The flowers are not only visually pleasing but are also known to attract various pollinators such as bees and butterflies, adding dynamic life to the garden. This ornamental plant is appreciated for its ability to bring height and color to garden borders, beds, and container plantings. Its floral display usually takes place during the warmer months, offering a long season of interest when many other plants have finished blooming. The Narrow-leaved Agapanthus is a popular choice for gardeners looking to add a touch of elegance and vertical interest to their landscapes.

WaterThe Lily of the Nile should be watered deeply once a week to ensure a good soak, especially during the growing season from spring through early fall. In the absence of rain, provide about one gallon of water per plant to saturate the ground around the root zone. Reduce watering during the dormant winter months, allowing the soil to dry out slightly between waterings. Overwatering or poor drainage can lead to root rot, so ensure proper soil drainage.
LightLily of the Nile prefers full sun to partial shade, with the best flowering typically occurring in full sun. An ideal spot is one where the plant receives at least six to eight hours of direct sunlight each day. They can tolerate light shade, particularly in hotter climates, but too much shade may reduce blooming.
TemperatureLily of the Nile thrives in temperatures between 50°F and 80°F, making it suitable for growing in USDA hardiness zones 8 through 11. It can endure occasional dips down to 20°F but sustained cold may damage or kill the plant. Protect from frost to prevent damage to foliage and roots.
PruningPrune Lily of the Nile after flowering to remove spent bloom stalks and encourage additional blooms. Annual pruning in late winter or early spring can help maintain plant shape and health, removing any damaged or dead leaves. Cut back foliage by about one-third to invigorate the plant for the upcoming growing season.
CleaningAs needed
SoilThe best soil mix for Agapanthus, commonly known as African Lily, is a well-draining, loamy or sandy soil enriched with organic matter. A soil pH that ranges from slightly acidic to neutral, about 6.0 to 7.5, is ideal for the African Lily. The incorporation of compost or aged manure can provide the necessary nutrients for optimal growth.
RepottingAfrican Lilies should be repotted every 2-3 years, or when the root system has filled the pot and is starting to become root-bound. Repotting in spring allows the plant to establish in the new pot before the growing season.
Humidity & MistingAfrican Lilies prefer moderate humidity levels but are quite adaptable to different humidity conditions as long as proper soil moisture is maintained. They do not require high humidity environments and can thrive in average home humidity levels.
Suitable locationsIndoor

Life cycleAgapanthus caulescens subsp. angustifolius, commonly known as Agapanthus or Lily of the Nile, begins its life cycle as a seed, which germinates in moist, well-drained soil. After germination, it develops a root system and shoots that grow into strap-like leaves. As the plant matures, it forms thick rhizomes or clumps, characteristic of perennial life. During its flowering stage in the summer, it produces tall stalks topped with clusters of funnel-shaped flowers, usually blue or purple. After pollination, typically by insects, the flowers develop into capsule-like fruits containing seeds, which are dispersed to start a new life cycle. During winter, the leaves may die back, especially in colder climates, but the rhizomes remain dormant underground, ready to regrow in the spring.
PropogationPropogation time
Spring to summer
Propogation: The most popular method of propagating Agapanthus, commonly known as Lily of the Nile, involves division of the plant's clumps. This is typically done in the spring or early summer when the plant is coming out of dormancy and beginning active growth. To propagate by division, carefully dig up the parent plant and gently separate the clump into smaller sections, ensuring that each piece has at least one or two growing points or shoots. Replant these divisions immediately at the same soil depth they were growing at originally, spacing them about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow room for growth. Water the new plants thoroughly after planting to help settle the soil around the roots. This method of propagation allows for quick establishment and flowering within the next growing season.
