Agapanthus africanus, commonly known as the African lily, is a herbaceous plant belonging to the Amaryllidaceae family. It has a bulbous stem and linear lanceolate or strap-shaped leaves that are leathery in texture.

The leaves emerge from rhizomes. The flowers are arranged in umbels and are funnel-shaped, with colors ranging from deep blue to white.

It produces capsules and blooms from July to August, with the fruits ripening in autumn. It is named “African lily” due to its abundant seed production after flowering.

The African lily is native to South Africa but is widely cultivated throughout China. It thrives in warm, humid, and sunny environments, preferring cool summers and warm winters.

Agapanthus africanus

It should be protected from strong direct sunlight during the summer and provided with ample sunlight in the winter, while avoiding waterlogging. Propagation of the African lily can be done through division or sowing.

The African lily has a warm nature and a pungent taste. It is believed to promote blood circulation, treat abscesses and swelling, disperse stasis, and have detoxifying properties.

It is named for its abundant flowers, which symbolize “visiting in love” and “communication in love.” With its lush green leaves, beautiful flower shape, and elegant colors, the African lily is an excellent choice for ground cover and floral arrangements.

I. Botanical History

Agapanthus africanus

The African lily is named for its abundant seed production after flowering.

II. Morphological Characteristics

Stem: Perennial herbaceous plant with a height of 50-70 centimeters. It has short rhizomes.

Leaves: Basal leaves arranged in two rows, strap-shaped, smooth, and dark green.

Flowers: Flower stalk emerges from the leaf rosette, reaching a height of 40-80 centimeters. The flowers are arranged in umbels and have six united tepals, forming a bell-shaped funnel. They are bright blue in color.

Fruit: Capsules containing numerous winged seeds. Natural flowering period is from July to September, with fruit ripening from August to October.

III. Growing Environment

The African lily is native to South Africa and is widely cultivated throughout China.

IV. Distribution Range

The African lily thrives in warm, humid, and sunny environments. It prefers cool summers and warm winters, with temperatures ranging from 20 to 25 degrees Celsius from May to October and 5 to 12 degrees Celsius from November to April.

If the soil humidity is high and the temperature exceeds 25 degrees Celsius during the winter, the stem and leaves will grow vigorously, hindering dormancy and affecting normal flowering the following year.

Light exposure also has an impact on growth and flowering. The African lily requires loose and fertile sandy loam soil with a pH level between 5.5 and 6.5.

V. Propagation Methods

The African lily can be propagated through division or sowing.

Division: It is best to divide overcrowded mature plants in spring, around March or April, during repotting. Each pot should have 2 to 3 clusters of plants. Plants divided in the autumn after flowering can also bloom the following year.

Sowing: Germination occurs around 15 days after sowing, and the seedlings grow slowly. It takes about 4 to 5 years of cultivation for them to bloom.

VI. Cultivation Techniques

Greenhouse cultivation: Proper drainage measures should be in place to prevent waterlogging. The African lily should receive at least 8 hours of direct sunlight per day, with shading facilities provided as necessary.

The ideal growing medium is sandy loam rich in organic matter, which should be sterilized by formaldehyde fumigation before use. The planting density is 6 to 8 plants per square meter, with equal spacing between seedlings.

Watering: The African lily prefers slightly moist soil conditions. Except for a thorough watering when the flower stalk is about to emerge, excessive watering should be avoided throughout the production process.

During the hot summer, it is recommended to mist the plants 1 to 2 times a day. In the cold winter, watering can be done approximately every 4 weeks.

Fertilization: Before planting, bone meal can be applied as a base fertilizer at a rate of 1 kilogram per square meter, which should be evenly incorporated into the soil.

In spring, before new leaves emerge, before flower bud differentiation in summer, and after harvesting cut flowers in autumn, a liquid fertilizer with a nitrogen, phosphorus, and potassium ratio of 1:1:2 should be applied as a top dressing.

Light exposure: The African lily should be shaded when the temperature exceeds 30 degrees Celsius. During the low-temperature periods of winter and spring, full-day exposure to sunlight is beneficial for increasing cut flower yield and improving quality.

Ventilation: During the peak growing season, it is recommended to open windows for 4 to 6 hours a day. During the slow growth stage, if the indoor air temperature is not too high, opening the windows for 1 to 2 hours every other day is sufficient.

Temperature: The temperature should be maintained between 15 and 28 degrees Celsius. If the temperature exceeds 30 degrees Celsius during the summer, misting the plants can help cool them down.

The African lily is not tolerant of low temperatures, and the overwintering temperature should not drop below 5 degrees Celsius.

Weeding: Cultivating the soil once a month promotes better plant growth.
Pruning: Regularly trim the yellowing leaves at the base of the plants.

Harvesting: It takes approximately 24 months from planting new seedlings to harvesting mature flowers. After that, mature flowers can be harvested once a year. After about 5 years, it is recommended to replace old plants by dividing clusters of African lilies.

The best time to harvest is when the flower buds on the inflorescence are fully colored. The harvested flowers should be sorted and bundled in groups of 10 stems.

VII. Pest and Disease Control

Common diseases of the African lily include leaf spot and red spot disease. Leaf spot can be controlled by spraying a 1000-fold dilution of 70% methyl thiophanate wettable powder.

For the prevention and control of red spot disease, care should be taken to prevent water droplets from falling on the leaves during watering. If infection occurs, spraying with a 600-fold dilution of Bordeaux mixture can be effective.

VIII. Main Values

Medicinal Value

The African lily has a warm nature and a pungent taste. It is believed to promote blood circulation, treat abscesses and swelling, disperse stasis, and have detoxifying properties.

Garden Value

With its lush green leaves, beautiful flower shape, and elegant colors, the African lily is an excellent choice for ground cover and floral arrangements.

Economic Value

The African lily can be used as a cut flower and is suitable for floral arrangements and vase displays. It is also a popular potted plant for indoor decoration, especially in semi-shaded areas in southern China.

It can be used as a decorative plant in rock gardens and flower beds. In northern China, it requires greenhouse cultivation for overwintering, while in warmer regions, it can be grown in courtyard gardens.

IX. Plant Culture

The African lily is named for its abundant flowers. It symbolizes “visiting in love” and “communication in love” in the language of flowers.
