The few species within the genus were hybridized intensively, yielding thousands of attention-grabbing and dramatic cultivars. regardless of their large reputation between gardeners, notwithstanding, there hasn't ever been a very finished booklet at the genus, an oversight that has ultimately been corrected through writer Wim Snoeijer, operating in live performance with Holland's Royal Boskoop Horticultural Society.

Extra info for Agapanthus: A Revision of the Genus
The best known genera belonging to this family are Agapanthus, Allium, Brodiaea, Dichellostemma, Ipheion, Leucocoryne, Nothoscordum, and Tulbaghia. The family can be divided further into subfamilies. To the subfamily Agapanthoideae belong only Agapanthus and Tulbaghia. Taxonomists still do not agree in which family Agapanthus should be placed. It is also considered to belong to the family Amaryllidaceae. Fortunately, in 1985 a revision of the monocotyledons was published by Dahlgren, Clifford, and Yeo, but, as you can guess, not all that was written is accepted.
Africanus ‘Albus’, A. inapertus ‘Albus’, and A. praecox ‘Albiflorus’—Agapanthus cultivars are no longer linked to a species name. According to ICNCP-1995 art. 3, cultivar groups should be demarcated by round or square brackets (I chose round). The choice of cultivar group for a particular cultivar is either supplied by the contributors mentioned or based on personal observation or on illustrations in combination with other details. Typography The ICNCP-1995 also advises on the typography of the cultivar and cultivar-group names in art.
Clearly the wild plants of Agapanthus are very variable. Because of this variation it is difficult to recognize species and/or subspecies, as Leighton stated in her monograph. In cultivation too nomenclature is still very confusing, especially given A. umbellatus, an incorrect name that has been used for different species and cultivars. Chapter 4 Classification of the Cultivars The classification of the cultivars proposed by Gillissen (1980) in his little-known report is simple and practical, but sadly no later references use it.
