Agapanthus is commonly known as "Lily of the Nile", but it is not a lily and all of the species are native to South Africa from the cape to the Limpopo River.
It is a plant that requires little attention here in the south. The rhizomes only have to be divided from time to time. There is a fungus that can attack the leaves at the center of the plant, if they are left too damp. This results in curly, mis-shapen leaves which can easily be cut out and discarded to prevent the spreading of the fungus. Otherwise, these are dream plants to cultivate.
Even though there is a big emphasis on the AZUR of the blue coast, I think that the most significant blue in the south of France is this tantalizing hue that is so difficult to capture on film.
We find this deep blue in the sky at certain times of the year and just now I am surrounded by the king of the Limpopo River, the jaunty, generous, blossoms of the Agapanthus.
