Oleander is the name of a flowering shrub belonging to the genus Nerium, which is poisonous to humans if ingested. The name comes from Late Latin lorandrum from Ancient Greek rhododendron meaning “rose tree” from Ancient Greek elements rhodon (rose) and dendron (tree). The spelling of the name may have been changed to resemble Latin olea meaning “olive tree” because it apparently resembles an olive tree.
