Virused Narcissus "Tete a Tete" never seemsto die, whereas N cyclamineus (one of it's parents) seems to become virused very easily and die as a result. Tete a Tete seems to act as a source of infection to other daffodills and I havn't seen any without virus symptoms for over 20 years. I weed it out whenever I can, in gardens I work in, and wont have it near my own collections.
