Tracey, what's your favorite?
My Father (who also was a lily hobbyist) favored Casa Blanca for it's beauty and purity of white colour. When Stargazer was created, he thought that was "the most beautiful lily ever created and destined to be of universal appeal". Guess his forecast was right. When he passed, Friends and Family decorated the parlor with lilies and six dozen or more Casa Blancas and Stargazers drapped his casket.
Besides Seafarer, I have about five or six others that I have high regards for because aside from well balanced beauty, they represent either a high level of achievement or have survived in the marketplace for a long time. Of course, the first to open in the Spring each year is always pretty (prettiest), right?
