I can start , here are some that I know .

........Canadian hybridizers

Barrie Matthie zone 6a - out of Ontario cultivars often start with "Bonibrae

Coral Kincaid zone - out of Nova Scotia

Allan Banks zone - out of Nova Scotia

Cecil Dunlap zone - out of Nova Scotia

John Clarke zone - out of Ontario

Mike Georges zone 6 - out of Ontario

L.Lagroix zone 4 - out of Quebec

Bryan Culver zone 5 - out of Ontario

Joe Hawkins zone 5 - out of Ontario

Don Longton zone 5 - out of Nova Scotia

Daniel Matton zone - out of Quebec

Dave Mussar zone 5 - out of Ontario

Josee Ratte zone 4 - out of Quebec

That's a start . I will update as I think of them

I have only recently started paying attention to hybridizers. The only ones that I have consistently had problems besides Maryotts are Petit, Lambertson, and to an extent, Stamile. I need to look through and see which ones have done the best, don't I? I am very interested in this thread. I do love daylilies with watermarks, and have fallen in love with Judy Davisson's daylilies. I have not grown them long, 3 or 4 a couple of years, but they have multiplied really really, and handled a couple of difficult years really well.

Nan Wilkerson hybridized her plants in Louisiana. She no longer has a commercial garden because of health reasons.

Karol Emmerich - Minnesota

Curt Hanson - northern Ohio

John Benz - Ohio

Joel Polston - Ohio

John and Annette Rice - Kentucky

David Kirchhoff and Mort Morss started in Florida, but moved to Kentucky several years ago.

Tim Bell - Georgia

Dan Hansen, the Salters, Nicole Devito, all in Florida

Phil Riley started out in the north but most of his intros were bred in Florida.John Peat started out in Canada, but hybridzed in Florida in recent years.

Dan Trimmer started out in New York, but did most of his hybridizing in Florida. He has now closed his garden.

Ludlow Lambertson's early intros were done in New York, but most of his intros were done in Florida. The longer he's there, the more tender his plants have become.

Heather, I have several Stamile daylilies that grow well here, I can’t say any of them are new, just since 2003 or so. If you want to know which ones they are I will post a list for you.

Sherry

Really appreciate your input Debra !!!!!!!!!!!

Hmmm Interesting Sherry , yes please post your list of Stamile's if you have time . Then I can look up to see if they are SEV's or EV's . I am guessing SEV's would do better than EV's . If you could see my back yard today there would be no doubt in your mind as to why Florida daylilies just don't do well here .

A couple of observations based on my experience. There are winners and loosers that every hybridizer puts out, so to say this or that hybridizer always has this or that just wouldn't make sense............ As for foliage evaluations, that's always been the hybridizer's choice. Frank Smith was rumored to have solved the problem of what to call his by naming them all Sevs. Easy solution for him and I suspect the foliage designation (not necessarily tied to hardiness) has been fudged a few times by others too...........If you wish to know where a Hybridizer lives you may find the link below valuable. I sure do. It lists the state they live in currently...........................Maryl

Charlottes list of Daylily Hybridizers

Thanks for your comments MaryL . I am aware of Charlottes Daylily Diary unfortunately it is not a complete list of hybridizers . For Example Nan Wilkerson is not listed there. I am also looking for personal experiences with cultivars . Charlottes can't provide that kind of info .

Heather, here are the Stamile, some are older than I remembered, here goes:

El Desperado 1991

Lavender Heartthrob 2002

Little Showman 2007

Little Jet Setter 2008

Mysterious Eyes 2003

Magic Lake 2000

Night Embers 1997

Pastelline 1991

Ruby Spider 1991

Spectral Elegance 2002, has only been here two seasons, did marvelously

Troplical Delight 1996

Heather - I misremembered where Nan Wilkerson's garden was. It was acutally Louisiana - so farther south than Alabama. Her cultivars have all performed pretty well here - even the evergreens.

Debra

Thanks Debra , that is valuable info for someone like me growing in a zone 6 while Louisiana is a zone 8 to 9 . That definitely means they would be iffy for me to grow here.

Heather - Nan's cultivars may be hardier than you think. Hybridizer Mary Baker successfully grows several of them in Nebraska (Zone 5b), and Nan had a grower in upstate New York trial several of them before introduction.
