In the NGA database is a daylily called Lady Elizabeth. The plant info is for the AHS registered 'Lady Elizabeth'. Unfortunately there is a trade-named Lady Elizabeth, patented cultivar name 'Robbobeli', see patent here:

The registered 'Lady Elizabeth' is yellow. The pictures in the NGA database are of a white daylily, presumably the trademarked Lady Elizabeth ('Robbobeli').
That would make the NGA plant info from the registered AHS daylily but the pictures of the patented unregistered 'Robbobeli'. I'm not sure how we go about suggesting edits in this case? Do we even continue to list the unregistered but trademarked and patented one?
I also suspect the rust rating more likely relates to the unregistered 'Robbobeli'.
Edited to include advertisement showing trademarked Lady Elizabeth ('Robbobeli'):
