The oldest daylily that I have was labeled Rosa when I bought it years ago. It is the first to bloom in my garden and is very tall and always needs to be stacked up. It is a nice rosy color with an average sized flower but it is nowhere to be found in any database. Does anyone have any idea what the real name would be?? It is at least 30 years old and could have been hybridized by Marion Hagerstrom.

There's a 'Rosa' in the AHS registrations database:

Rosa (Childs-F., 1969)
height 36in (91cm), bloom 6in (15.0cm), season EM, Rebloom, Dormant, Tetraploid, Very Fragrant, Rose self with apricot throat. (Reverend Traub × Cathedral Bells)

Thanks, Sue. You are a better searcher than I. The only thing is mine is at least 48 tall.

Do you have a pic of it, or does it otherwise match the description? I was thinking maybe not since it's always first for you but registered EM. There are 16 Hagerstrom registrations in the AHS database but none have a name similar to 'Rosa'. There are 48 registrations that start with Rosa, 12 that end with rosa and a total of 87 that have rosa somewhere in the name. Searching on these with a minimum height of 40" narrows it down to 10 though and three of those are too new and also not likely to be abbreviated rosa. These are the remaining seven.

Rosa Fulvultra, Rosabel, Rosada, Rosalie, Rosalind, Rosalure, Tetra Rosalind
