African lily 'Oslo'


Agapanthus 'Oslo' is a perennial plant known for its striking blooms and attractive foliage. Commonly referred to as African Lily or Lily of the Nile, it showcases lush, strap-like green leaves that gracefully arch outwards, forming a lush, dense mound of foliage at the base. The greenery provides a beautiful contrast to the flowers that emerge atop long, slender stalks. The most captivating feature of Agapanthus 'Oslo' are its flower clusters. Each stalk is crowned by a large, rounded umbel composed of multiple individual trumpet-shaped flowers. These flowers are typically a deep blue or violet color, though some cultivated varieties may exhibit different hues such as white or lighter shades of blue. The petals are soft and slightly recurved, lending a delicate appearance to the otherwise hardy plant. Once in bloom, the African Lily becomes a focal point in any garden, drawing attention with its vivid color and bold, globe-like floral displays. The blooms are not only visually stunning but are also known to attract pollinators such as bees and butterflies, adding to the plant's allure and its role in the garden ecosystem. The overall appearance of Agapanthus 'Oslo' exudes a tropical appeal, though the plant is quite versatile and can thrive in a variety of climates, provided it is cared for properly. With its lush greenery and captivating flowers, the African Lily makes an excellent addition to borders, beds, and as a striking container plant, where its exceptional beauty can be fully admired.

  • water dropWater

    African Lily, commonly known as Agapanthus 'Oslo', prefers regular watering to maintain evenly moist soil, especially during its active growing season in spring and summer. It should be watered thoroughly once the top inch of soil feels dry, typically about once a week, with adjustments made for rainfall and temperature. Provide the plant with approximately one-inch of water each week, which equates to about 0.62 gallons for a medium-sized pot. In the winter, reduce watering to every other week or less, depending on indoor air humidity and temperature, ensuring the soil does not dry out completely.

  • sunLight

    African Lily thrives in full sun to partial shade conditions. The best spot for the plant is where it can receive at least six hours of sunlight a day, though dappled afternoon shade can help protect it during the hottest part of the day in warmer climates. A south-facing garden or a west or east-facing window for potted indoor plants are good locations to provide the light conditions it needs for optimal growth.

  • thermometerTemperature

    African Lily does best in temperatures ranging between 50°F and 80°F. The plant can tolerate brief periods of cold down to about 28°F but should be protected from frost to prevent damage. Ideal growth is seen when nighttime temperatures are cooler, around 50°F to 60°F, and daytime temperatures are warmer.

  • scissorsPruning

    Prune African Lily to remove spent flower stalks and encourage the plant to produce more flowers. Deadheading, or cutting off the faded flowers, should be done as soon as the blooms fade. In late fall or early winter, after flowering has finished, cut back foliage that has died back to tidy up the plant and direct energy to new growth.

  • circleLife cycle

    The life of Agapanthus 'Oslo', commonly known as Lily of the Nile, begins with seed germination, which occurs when conditions are warm and moist. The seedlings develop into juvenile plants, forming fleshy roots and strap-like leaves. As it matures, the plant forms a clump of evergreen or deciduous leaves, depending on the climate. Once mature, usually within a few years, it produces tall stalks topped with clusters of trumpet-shaped flowers during summer. After flowering, the plant sets seed capsules if pollinators have been active, and these seeds can be dispersed to grow new plants. In colder climates, Agapanthus 'Oslo' dies back to the ground in winter but re-emerges in spring, continuing its perennial cycle.

    • Propogation time

      Spring to Summer

    • The Agapanthus 'Oslo', commonly known as Lily of the Nile, is typically propagated by dividing its clumps. The best time for propagation is in the early spring or late summer when the plant is not actively flowering. To propagate by division, carefully unearth the plant, ensuring as much root as possible is intact. Gently separate the clumps into smaller sections, each with a portion of roots and foliage. These newly divided plants should then be immediately replanted in well-draining soil and watered thoroughly. Within a few weeks, the divisions will establish themselves and start to grow into new, independent plants. This method is favored due to its simplicity and the high success rate of the resulting plants.
