The moonflower
There is a plant called Ipomoea alba in Latin, but it also goes by the name of »Moonflower«, because its blossoms open in the evening and at night and because its round, white shape reminds of the full moon. It is native to tropical and subtropical regions, in particular Argentina, Mexico and Florida. The moonflower is a climbing plant and belongs to the genus ipomoea, incidentally, the same genus as a sweet potato (especially cultivated in China, Nigeria and Uganda).
