My oldest daylily is called Gold Dust from 1905 by yeld. I purchased it from someone on Ebay who inherited it when she purchased her house. I have not seen it bloom yet as I just received it this spring. I also have the following:
Black Plush by Connell - 1955 (new this spring)
Little Rainbow by Reckamp - 1963 (new this spring)
Bold One by Lennington - 1964 (new this year)
Mary Todd by Fay - 1967 (this one I have attached the bloom from this year.)
Dixie Land Band by Fleishel - 1969 (new this year)
Little Grapette by Williamson - 1970 (new this year - about to bloom)
Butterpat by Kennedy - 1970 (1 year old - have not seen it bloom)
Ed Murray by Grovatt - 1971 (2 yr old plant - it is about to bloom)
