Agapanto

Agapanthus is a genus of herbaceous perennials that mostly bloom in summer. The leaves are basal, curved, and linear, growing up to 60 cm (24 in) long. They are rather leathery and arranged in two opposite rows.
Some species of Agapanthus are commonly known as lily of the Nile, or African lily in the UK. However, they are not lilies and all of the species are native to Southern Africa (South Africa, Lesotho, Swaziland, Mozambique), though some have become naturalized in scattered places around the world (Australia, Great Britain, Mexico, Ethiopia, Jamaica, etc.).
