I'm looking for a 1982 seedling that is in the database, seedling # EW-81-021-D, (Hemerocallis 'Wynnaline Stinson'). The hybridizer was Winniford-E.
I don't know how to find out if the seedling became an available plant or not.
I would like to get one.

Looks like Archway Gardens that put it in the database, no longer has a web site. I guess that would have been to easy ;-). Good luck finding it.

It was initial assigned that number as a seedling, while the hybridizer evaluates it. Once it is decided that it will be registered, it is given a cultivar name, in this case, Wynnaline Stinson, and now no longer considered a seedling.
I do hope you can find it.
