Agapanthus is a genus of herbaceous perennial bulbs that mostly bloom in summer. Agapanthus is collectively commonly known as “Lily of the Nile”, but it is not a lily, and all the species are indigenous to South Africa from the Cape to the Limpopo River. Species boundaries are not clear in the genus, and despite having been intensively studied, the number of species recognized by different authorities varies from 6 to 10. A great many hybrids and cultivars have been produced and they are cultivated throughout warm areas of the world. Agapanthus can be grown within plant hardiness zones 9 to 11. In lower-numbered zones, the bulbs should be placed deeper in the soil and mulched well in autumn. Agapanthus can be propagated by dividing the bulbs or by seeds. The seeds of most varieties are fertile. Agapanthus is one of South Africa’s best known garden plants and is grown in most countries in the world. Their strap-like leaves and striking blue or white flowers make them favorites in plant borders as well as in containers.

Agapanthus inapertus ssp pendulous is the most striking Agapanthus of all the true Agapanthus species. With its compact head of drooping, dark violet blue flowers it is always commented on when first seen. The buds as they emerge seem almost black and are held erect, slowly elongating and finally becoming pendulous as they open. It is a deciduous species which has narrow light green leaves. Plants stand about 60cm tall, and the flower stems reach a height of 90cm. They flower in January and February in the Southern Hemisphere. The plants need abundant water during the growing season and should be planted in well-drained soil in full sunlight. They make good container plants and are best appreciated in the landscape as specimen plants or in small groups. They can also be mixed with other plants but must not be overcrowded or they will not flower well. Although deciduous, they do tolerate rain during their dormant period. They can withstand sub-zero temperatures for short periods. In the Northern Hemisphere plants in containers can be moved into a glasshouse during winter while plants outdoors should be covered with straw or similar material to help protect them.
