A 1966 reference states the parentage as 'Magenta' x unnamed seedling. Ludwig Tashner in writing an article on Blue Roses for Roseweb http://roseweb.co.za/wiki/rosewiki/index.php?title=Blue_Roses states "Messrs Kordes crossed ‘Sterling Silver’ with ‘Magenta’ and released ‘Silver Star’, ‘Cologne Carnival’ and ‘Lavendula’"
