Botanical: agapanthus cultivar
Discovered in the 17th century, and given the name "African Hyacinth", then later African Lily and finally Lily of the Nile, due not only to lack of geographic knowledge of the African continent at that time but also due to the keen marketing skills of nurserymen of the 19th century. Egyptology was all the rage.
Agapanthus is indeed from Africa but thousands of miles from the Nile, originating in southern Africa. It is not clear how or why it came to be named the "Flower of Love" (from the Greek Agape = love; and the greek Anthos = flower), but the name has stuck and remains with us to this day. Today there are several modern hybrids in deep Ultramarine, light blue, and white.
The "flowers" are actually umbels of many small flowers, or florets, displaced at the top of a long, robust yet slender stem. Agapanthus' also have very interesting green seed pods in late summer, early fall.
