Many plants in this country are sold as A. africanus.  That is interesting, but not surprising, that they are not likely to have anything to do with this species.

It is unlikely you have Agapanthus africanus or even an africanus 
hybrid. The plant is hardly in culture as it needs very hot and dry 
situations and is very difficult to grow. It has the highest amount of 
nuclear DNA ( 31.6 pg) and any hybrid with another species ( all 
other five have 22.3-25.5 pgram) is easeily spotted.  I did not found 
a single africanus hybrid among about 200 plants tested. Most if 
not all plants sold as africanus are A praecox
