The trend for a good number of years has been to research into finding Liliums and others that show no symptoms. SELF EXPLAINING. 'Tete a Tete' has been so heavily virused that they cleaned stock and this is incomparably better than the infected ones. Another one they cleaned by tissue culture is Hippeastrum papilio and this is also extra robust: evidently the original offset propagated papilio had a symptomless weakening virus.
