I am sharing this reply to an inquiry regarding my recent thread "Longest and Oldest Northern Grown Daylilies" about Barth Daylily seedlings.
There are currently a large number of seedlings being evaluated for possible registration and future introduction at O'Donal's Nursery in Gorham, Maine.
The evaluation process at O'Donal's is quite rigorous and can take one to three years or more. I am attaching pictures of six seedlings now under evaluation. All of these are tetraploids.
