Below are pictures of several rebloom daylilies available from O'Donal's Nursery in Gorham, Maine. I have been hybridizing daylilies for O'Donal's since 2010 when they purchased the rights to Barth Daylilies that began with my father, the Reverend Dr. Joseph N. Barth, in 1952 .Dr. Barth was a pioneer in the breeding of tetraploid daylilies.
In 1992 I created my first continuous blooming diploid seedling. Some 25 years later, while hybridizing for O'Donals, created COUNTY ROAD ENCORE,
my best continuous bloomer to date. Then, LEMON SQUEEZE ENCORE, a repeat blooming diploid. Earlier, also at O'Donal's, DAMARISCOTTA RIVER
GREAT PUMPKIN, my first large tetraploid repeat bloomer. Jeffrey O'Donal, the owner of O'Donal's (professional horticulturist), has also been
daylily hybridizing and has created reliable large tetraploid rebloomers. O'Donal's has a website.
Developing reliable reblooming daylilies for the north takes perseverance and great deal of patience. I suspect all the continuous and repeat blooming
daylilies at O'Donal's would likely also do well in Tennessee.
Please don't hesitate to contact me, or Jeffrey O'Donal, to learn more about the reblooming daylily program at O'Donal's.
