~Frostline Daylilies is the dedicated website for the daylily introductions of Northern Grown Perennials.

• Northern Grown
• Northern Hybridized

To many hybridizers, northern means zone 5 in the relative warmth of Indiana, Illinois or Ohio. To us, northern means a frigid zone 4 in Wisconsin.

To produce for the gardening public a diverse array of daylily hybrids which exemplify both beauty and hardiness for a wide range of settings. All our daylilies are field grown on our Wisconsin farm and nursery.

To be considered for introduction, our daylilies must meet the following standards:

• Distinctive Beauty of Bloom
• Good Foliage and Plant Habit
• Vigor
• Hardiness

When you purchase any Northern Grown Perennials introduction you are covered by a two-fold guarantee. First, you must be pleased with the plants upon receipt. Second, grow our introduction for two full seasons, and if at the end of the second growing season you are not entirely pleased, just return the undivided clump with original shipping label and name tag. In both cases we will without hesitation refund both the original purchase price and your shipping costs. No one has yet to take us up on this guarantee, and we intend to keep it that way. We want you to be entirely pleased with our plant introductions.

Tetraploid; Semi-dormant to Dormant 34 in. tall 5.5 in. bloom; mid to late season bloomer; 22-25 buds, nicely branched Stemming from the same lines as our popular 'Sable Song', this dark mid to late season bloomer has proven a step forward in our hybridizing goals for clean, dark color. The flower form is very round, with ruffled, recurving segments. Even on cool mornings, the blooms open readily. The clean dark sable color of the segments contrasts sharply with a dominant, dark green throat. Blooms are held well above foliage on tall, sturdy, nicely branched scapes. Foliage is broad and dark green. The whole of the clump has a dramatic impact, with everything in balance. Bloom season is staggered and prolonged. Fertile both on pod and pollen, we were impressed with our first small run of seedlings bloom from 'Ebony Standard' last summer and are anxious to see more extensive maiden bloom in 07. The whole of the plant has a finished quality to it, lending true garden impact. Good grower, quickly forming a presence.

Tetraploid Semi-evergreen 32 in. tall 5 in. bloom; mid season bloomer; 18 buds Blaring red-orange lava hot! That's one way to describe the effect of 'Color Me Hot'. The basic image is a creamy apricot-orange base upon which has been applied a burning hot red ember center zone which bleeds out onto the petals. Petals are usually lightly rimmed with the same red-orange tone. Sepals recurve to lend full attention to the central colors. Tends to be a semi-evergreen most years, but very hardy and a vigorous grower, quickly forming an impressive clump. Staggered, prolonged bloom even while the bud count is not exceptionally high. This bloom has instant impact with its burning hot coloration, which holds well even in very hot weather. Both pod and pollen fertile. We have used it every year since its maiden bloom and have a wide range of interesting colors stemming from it. Scapes are strong and have enough height to show bloom a long way off. 'Color Me Hot'-loud, brassy, molten, demanding…and the list goes on.

Tetraploid Dormant 36 in. tall 6.5 in. bloom; mid season bloomer; 24 buds; nicely branched From its debut in the seedling patch, we have been pleased with 'Dragon Rider'. It has a tailored, rather ufo flair. The wine-purple color is very clean and deep, accentuated the more by a strong green heart which bleeds out chartreuse-to-white onto the flower segments. The blooms bear impact from a distance, held up on tall, sturdy, nicely branched scapes. At a closer viewing the often recurving and twisting flower parts lend an air of informality. Feeling that the tailored foremat and twisting segments might lend themselves readily to our tet spider crosses, we set a large number of pods on 'Dragon Rider'. The first large batch of kids bloomed in 06 from these crosses and we were very pleased with the results, choosing several for possible future introduction. Easily fertile both ways. Foliage is broad and deep green. Plant vigor is strong, quickly forming a very large clump. An established clump in bloom literally has a canopy of purple when in bloom.

Diploid Semi-dormant to Dormant 22 in. tall 3.5 in. bloom; mid season bloomer; 20 buds While the main scope of our hybridizing has been with large size tetraploids, we have always made a few crosses each season with our mini/pony sized seedling lines as well. 'Eye Sign' has been at the center of these crosses in the last few seasons. We are propagating a number of its progeny for future introduction. 'Eye Sign' has what can be referred to as a finished bloom. It is consistent in its presentation, every bloom an eye-catcher. Base color varies a bit, depending on temperature, but can be called a creamy yellow-sometimes with pink undertones. A bright cherry red, the eye is intense and dominant! An interesting feature is that there is a semi-circular notch on the eyezone on each petal. Another feature that makes the bloom even more contrasty is the intense, bright green throat. The segments recurve consistently, forming a very round bloom. Petals are rulled and fluted to perfection. A clump is beautifully balanced in regard to height and bloom presentation. Sharp and snappy to the nth degree, 'Eye Sign' always makes its presence known.
