"Daylilies on Ice" is the one stop web page for locating daylily hybridizers in cold winter hardiness zones 3, 4 and 5.

Springwood Gardens - Minnesota, USA. Our goal is to produce cutting edge, distinctive, northern hardy daylilies which perform well in the garden and have beautiful, clear (or even unusual) color or interesting patterns.

Culver Farm Daylilies - Ontario, Canada. Some of the goals we have at Culver Farm are hybridizing daylilies that are hardy, vigorous and healthy plants for our northern climate. We try to pick out of our hybridizing program daylily flowers that have good clear colour. All the daylilies are grown in field conditions without the aid of any artificial benefits to enhance daylily growth. The freeze thaw cycles we received during most of our winters weed out the weak and unsuitable daylilies for our climate. Daylilies that will flourish under ordinary garden conditions are a major goal for me.

Solaris Farms - Wisconsin, USA. The Bremer's Solaris Farms specializes in far northern hardy daylilies and hybridize for this much needed plant characteristic. Our mission in hybridizing is...better plant, better scapes and better flowers in that order! Solaris Farms is located in an area of harsh winter climate that experiences greater than normal freeze-thaw cycles, icing and exposure. With these factors in mind, Solaris Farms is working on programs involving clear vibrant colors, unusual forms and ruffling of reds. Both diploid and tetraploid daylily lines are worked with. Great garden daylilies must not only survive, but produce.

Blue Hill Country Garden - Maine, USA. My journey into the world of Daylilies began about 15 years ago. As this passion for the flower we all share grew I found the most satisfaction in growing daylilies came from hybridizing my own seeds, nurturing them through maturity, and judging their potentials.I work with both diploid and tetraploid flowers. My hybridizing goals are for hardiness, large flowers that are early morning openers (EMOs) and flowers that open flat after cold nights. I want my introductions to have it all - a pretty face and a solid cold hardiness along with quality plant habits. Ten years after raising my first daylily seeds I'm starting to see some good results. In 2004 I registered my first three daylilies one unusual form and two large flowered tets.

Pinewood Gardens - Wisconsin, USA. We are a licensed nursery located in northeast Wisconsin in a zone 4 climate and specialize in hardy northern daylilies. Our daylilies have to survive cold winters often with little snow. We also have cold spring weather, late frosts and cool summer nights. In our hybridizing program, the most important characteristics to us are consistent opening, hardiness, great garden performance (lots of flowers, well budded and branched scapes), and a high percentage of perfect flowers. Our weather challenges daylilies to perform well throughout the bloom season.

Nova Scotia Daylilies - Nova Scotia, Canada. I have been collecting and growing daylilies for the past eight years. It is an ongoing experience to try new daylilies to see which ones will perform the best. I have found that most of them will survive in my zone 5 garden. However, surviving and performing well are miles apart in the enjoyment of the plant. Fortunately, there are some dedicated Northern hybridizers whose priorities are daylilies that not only have beautiful flowers, but have a plant underneath the flower that will grow well and look good before, during, and even after bloom season. These are the types of daylilies I hope to grow more of in my garden.

North Country Daylilies - New York, USA. Twelve years ago we moved to upstate NY from Long Island, and shifted from a zone 6/7 climate to a solid zone 4. I quickly found that many daylilies that fared well in my old garden, performed very poorly at the farm. I hybridize tetraploids, so went back to some of the older well-branched dormants from hybridizers such as Don Stevens, Steve Moldovan, and Virginia Peck for my initial base. Since then I've integrated some hardy southern stock into my lines, and now have a stable of daylilies that thrive, not just survive, in zone 4. I want to be known for daylilies that are an asset to the garden, regardless of snow cover or cold, and that have sufficient bud count and branching to provide a long bloom period.

Hillside Daylilies - Ontario, Canada. I have been seriously growing daylilies since 2000 and have been hybridizing from the beginning. A primary focus in my program is to develop a spotted daylily. There are a number of speckled cultivars currently available but none with distinct spots. Another aim is to explore the genetic potential of some of the newer and last cultivars introduced by the late Brother Charles Reckamp. Northern hybridizers like Culver, Mason, Schaben and others are well represented in my garden.This is not a commercial garden as I have yet to develop a plant I consider worthy of registering however I do sell seeds and some of my plant increase on the Daylily Auction and privately.

Donís Daylily Hybrids - Nova Scotia, Canada. I focus on large flowered, heavily ruffled varieties hoping to realise northern hardy, vigorous, branching and buds. I am using mostly recent intros in my program including Evergreens and Semi Evergreens with pretty good results. I have some wonderful , hardy seedlings to work with.Time will tell ultimately. I am holding back registering any for now while I see how they perform. I do sell off my seedlings that I donít keep if they are too nice to compost.
Don Longton

Red Lane Gardens - Prince Edward Island, Canada - Zone 5. I have been growing Daylilies for about 25 years and hybridizing for about 8. My early goals were focused on small flowered diploids on taller plants, but that has expanded to include Unusual Forms as well as tetraploids. Height (6' plus) is still a major goal, but whatever the category, the plant itself must come first...its vigor, hardiness and foliage. As well, they must live up to the Daylily's perfect perennial status and have good branching, bud count and scape production. 2005 will see the first introductions registered and the first crop of F2 seedlings will be blooming for their 3rd year.

Northern Lights Daylilies - Minnesota, USA - Zone 4. I have been hybridizing for a while but a few years ago I began a program to bring more of the best blood from all over the country and combine it with my own lines. My breeding goal is to produce very moden flowers on plants that are hardy, well branched and well budded. I especially like taller very round and ruffled flowers as well as doubles. I also focus on flowers that are capable of instant rebloom even in my zone 4 garden. The gardens are located on a hillside and have rich loam soil with a relatively high pH. I fertilize my plants and water them by hand as needed. The seedlings are not sprayed so as to be able to evaluate them for disease and insect resistance. I hope you enjoy my flowers!

Knoll Cottage Daylilies - Massachusetts, USA - Zone 5.  I became established as a selling garden and an AHS Display Garden in 1995, and by 1996 I was hybridizing for tetraploid Unusual Forms that are northern hardy and survive in a climate that has killed many perennials and shrubs normally hardy to Zone 5.  My hybridizing efforts have also led me to create very large 6Ĺ to 9 inch flowers that do not fall into the criteria of a UFo, but are just beautiful and eye catching and tall.  See my web site for introductions since 2007, and then look into the Futures of what is to come.
