Nerine sarniensis, commonly known as Guernsey lily or Jersey lily, is a species of flowering plant in the family Amaryllidaceae. It is the type species of the Nerine genus. It is widely cultivated in the temperate world and is particularly associated with the island of Guernsey, as reflected in both its Latin and common names (sarniensis means "from Guernsey"), though it does not originate there, nor is it a true lily (it is more closely related to Amaryllis and Sternbergia). It is native to the Northern and Western Cape Provinces of South Africa, though it is now naturalized in France, Madeira and the Azores.
