African lily 'Midnight Blue'


Agapanthus 'Midnight Blue', commonly known as Lily of the Nile, is an ornamental plant noted for its striking deep blue, almost purple flowers. The plant features lush green, strap-like foliage that forms a dense clump, elegantly arching and providing a rich backdrop for the bloom display. These leaves are deciduous or evergreen depending on the climate, contributing texture and color to the garden year-round. The flowers of the 'Midnight Blue' emerge on tall, upright stems that rise gracefully above the foliage. The blooms themselves are arranged in large, round clusters known as umbels, which have a globular and captivating appearance similar to fireworks when viewed from a distance. Each individual flower within the cluster is trumpet-shaped, featuring a dark blue to purple hue that is rich and eye-catching. The contrast of the dark blooms against the bright green leaves makes this particular variety of Agapanthus a sought-after plant for gardeners looking to add a splash of vibrant color to their landscape. In addition to its aesthetic appeal, the flowers of the Lily of the Nile hold a certain allure for pollinators such as bees and butterflies, making it not only a visual highlight but also an ecologically beneficial addition to any garden.

  • water dropWater

    Lily of the Nile, commonly known as Agapanthus 'Midnight Blue', should be watered generously during its active growth season in spring and summer. Providing water once a week, amounting to about one to one and a half gallons per plant, will ensure adequate moisture. As the plant enters dormancy in the fall, reduce watering to every other week. Throughout the winter months, minimize watering to just enough to prevent the soil from completely drying out, perhaps as little as half a gallon every couple of weeks. Always check the top inch of the soil before watering; if it feels dry, it’s time to water.

  • sunLight

    Lily of the Nile thrives in full sun to partial shade. The ideal spot offers at least 6 hours of direct sunlight daily. Although they can tolerate some shade, the best flowering is achieved in a location where the plant is exposed to ample sunlight. Avoid deep shade, as it can lead to reduced blooms and weaker growth.

  • thermometerTemperature

    Lily of the Nile prefers temperate climates and can survive in temperatures as low as 20°F, but it thrives in areas where the temperature ranges between 50°F and 80°F. Frost can damage the foliage and blooms, so in regions with severe winters, it is best to provide some protection or move potted plants indoors.

  • scissorsPruning

    Prune Lily of the Nile to remove spent flower stalks and encourage a tidy plant appearance. This task is typically done in late summer or fall, after the blooming period is over. Lightly shaping the plant by trimming away any dead leaves or old foliage can be done in late winter or early spring before new growth starts. It is not necessary to prune regularly, but tidying up the plant can promote better blooms the following season.

  • circleLife cycle

    The life of the Agapanthus 'Midnight Blue', commonly known as the African Lily, begins with seed germination, which occurs in warm, well-drained soil with ample sunlight. After germination, seedlings develop into juvenile plants with elongated strap-like leaves. As the plant matures, it forms an evergreen perennial clump that grows larger each year. The African Lily produces tall flower stalks in the summer, bearing deep blue to purple globular flower clusters at their tips. Following pollination by insects, the flowers develop into seed capsules, which when dry, release seeds to propagate the next generation. In colder climates, the plant may die back to the ground in winter but will resprout from its rhizomatous root system when warm temperatures return.

    • Propogation time

      Spring to early summer

    • The Agapanthus 'Midnight Blue', often known as the African Lily, is commonly propagated through division. The best time for this is in the spring after the threat of frost has passed but before new growth begins in earnest. To propagate through division, the grower should carefully lift the plant from the ground, making sure to keep a generous amount of soil around the roots to minimize shock. Using a sharp knife or spade, the clump is then divided into smaller sections, each with a portion of the roots and at least one or two growing points. These divisions are then replanted at the same depth they were growing previously, ensuring they are spaced about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow for adequate growth and airflow. Watering the new divisions thoroughly after planting is crucial to help reestablish the plants. This method is favored for its simplicity and the speed with which new plants can become established.
