History of Knock Out RoseWilliam Radler Develops Hybrids That Are Knockouts By STEWART DEMPSEY From the July 9, 2006 edition of the Milwaukee Journal Sentinel It is hard to imagine a garden without roses. Their captivating beauty and lore are entwined in the hearts and minds of gardeners everywhere. So strong is the connection to this flower that gardeners would often spend more time and effort growing their roses than any other flower. But today, in large part because of one local man’s lifetime work, we can enjoy the beauty of roses with little of the effort once required. William Radler is responsible for many of the easy-to-grow new roses that are extremely disease-resistant, drought-tolerant and ever-blooming. In 2000, the All America Rose Selections committee named Radler’s original red Knock Out shrub rose as one of its winners and it quickly became the best-selling new rose on the market. Last year alone, some 3 ½ million Knock Out were sold, a total only this rose can claim. Radler’s Pink and Blushing Pink (a paler version) Knock Outs followed to equal acclaim. And Radler’s Rainbow Knock Out was just named an All America Rose Selections winner for 2007 and will be available next year. Radler spent his earliest years living with his family at 7th and Burleigh streets in Milwaukee. They were living in Whitefish Bay when he bought his first rose at a local A & P store with money he saved from his allowance when he was 9. His parents warned him that the plant would not survive the winter. Radler was confident it would, and the following year the plant thrived. From this early fascination, he developed a lifelong passion to develop and improve upon the rose. He went on to earn a degree in landscape architecture and served as the director of Boerner Botanic Gardens, all the while working on breeding roses as a hobby. Hundreds of Roses He now is a full-time rose breeder. His 1 ½ acre lot in Greenfield with its hundreds of rose bushes is his laboratory. In 1992, when he moved to his current home and garden, it was the yard and not the house that drew him to the property. He calls it the Rosarium. His basement is a facility for developing new roses and an incubation area for seedlings waiting for evaluation and possible inclusion in the outdoor Rosarium. These roses are tested and evaluated for disease resistance, repeat blooming, winter hardiness, resistance to insects and many other desired qualities. “I keep on selecting the best and continue crossing and crossing,” he says. “There are five hundred or more rose seedlings in the basement at any given time.” What does he look for in a rose seedling? The three most important characteristics at this early stage are breaking, habit and flower. Breaking is how, when and where the plant naturally sends out additional shoots from the main stem. Habit is the overall growth pattern of the plant (dense and bushy, or tall and spindly, for example). Flowers are rated on color, size, petal count and fragrance, among other things. Initial evaluation is critical, but some characteristics will change once the plant is grown outdoors. Developing a rose, even for someone with a horticultural background, is not an easy task. It takes a rare individual with the skills to recognize what he is looking at, and someone with an enormous amount of patience. At its introduction, Knock Out set the standard for Black Spot resistance and repeat bloom. This beauty has single, bright flowers all season that seemingly float above dark green, lustrous and disease-free foliage. Knock Out is winter hardy, and is self-cleaning (no dead flower removal is necessary). Its path to market was long and painstaking for Radler. “The very first crosses I made were in the 1970s,” he says. “Knock Out first saw the light of day in 1989. Knock Out was the only seed in a hip from a reluctant female.” It can take years to get the right crosses, and there are so many factors including weather, temperature, viability of seeds and genetic unpredictability that can impede the quest for the perfect rose. Making it disease-free To ensure disease resistance, the roses in the Rosarium are inoculated with disease pathogens. “I encourage disease on the property,” says Radler. Infected leaves are dried and ground in a blender then spread on the healthy plants when the leaves are wet. Overhead watering during the growing season guarantees the spread of disease. Resistant plants are easily observed and documented, then used in future crosses. “In the fall of the year disease and insects are at their peak. Does a rose still look great? It has to look good. That’s what people are looking for,” he says. The plants are further tested and analyzed by the companies responsible for propagation and commercial sales, such as Conard-Pyle Company/Star, the company testing and producing of many of Radler’s introductions. This year’s introduction is Bright Eyes. It is an upright, pillar-type shrub rose that also can act as a medium sized climber, suitable for smaller gardens. Its flowers are a delicious salmon-pink with a lighter central eye. In addition to superior hardiness and disease resistance, Bright Eyes is a repeat bloomer and has a lemon-spicy aroma. Other recent introductions besides those in the Knock Out series include Carefree Sunshine, and Ramblin’ Red. Some of the roses credited to Radler actually are mutations of his roses. And what does Radler say of his success? “I’m overwhelmed,” he says. “I can’t believe this has really happened to me. What started as a hobby for me has resulted in what has been called the most sought-after rose in the country. I’m beyond proud. “But what’s truly wonderful is that something that has brought such joy to me has also helped gardeners who never thought they could grow roses.”

Thank you Zenman; what you mention actually seems quite encouraging, since i'm beginning to think that cost of final development might well be the biggest question as to this project getting (hopefully) finalized at this time. Especially with all the austerity things going on. A potentially low-cost way for things to perhaps proceed, could well be the key or the key to this happening sooner rather than later. In the long run, I have to think that something like project and its finishing, is fairly bound to happen...at some point. Each piece of pertinent information that can be found or offered, may well prove another piece of the puzzle put into place. I'll certainly plan here on GardenWeb to come by at least once in a while or as things happen, to update. Actually, as I just noticed, I have something right now to say, being alas, a distinct correction in what I wrote. I entered the wrong name as to the common name of the disease, and further, I even garbled the scientific name. I listed "mummy berry" as the common name, and some mishmash or other (got the two parts backward I guess) as to the Latin name. The scientific Latin name, properly,is Pucciniastrum geoppertianum, often shortened of course to P.geoppertianum.

The contraption below uses 18 watt CFL's. It has 12 of them. There is enough room for 16 *** 5 gallon bucket trees or one year i did 16 pepper plants in 5's. The walls of the box should be aluminum foil lined. This holds the heat and humidity in. In my case 50% of my heating bill is the meter charge before I use any gas. It cost just as much to heat with gas as it does with CFL's. Might as well grow beats, citrus trees and garden starts. If I lived in KY just 5 miles south I would not get that meter fee and it would be a waste of money. Might as well purchase my garden starts from home depot and buy my citrus fruits at Kroger's fruit department. Save my yard for apple peaches pears and plums. June 23rd my birthday comes. If you heat with oil, electric, or propane, It is no more to heat with CFL's. Might as well grow citrus trees in the basement. Pip is absolutely correct with his diagram for an open room. The center bulb can be remove with only a little loss to the trees. however if you use the container I use with the bright white/foiled walls you can do what I did. T*****T******T******T **L****L****L****L T*****T******T******T **L***************L T*****T******T******T **L**************L T******T******T******T The above was the exact setup for my pepper plant. I was picking peppers 5 weeks before frost safe set out date. It really does pay to grow green and peppers in with your citrus tree with the $$$$avings in organic produce and tree growth advancements. Notice the beets on the first level to provide heat for the roots of the citrus trees above. We had a death in the family and my wife collected many memories. As a result we have no room anywhere in our house and we lost the ability to grow greens. The greenhouse is not warm enough. Heating the greenhouse is $$$$$$$$$$$$ out of the question. The link below shows the things I did that REALLY WORKED WELL. Here is a link that might be useful: http://s1094.photobucket.com/user/wreristhechimney/slideshow/sunshine2013

Thank you for the references, but, most evidence suggests that increased anthocyanin synthesis is sometimes an effect of cold exposure rather than the cause of cold tolerance. Note: ----------------------------------------------------------------------------------------------------------- Decades ago, Parker (30) linked anthocyanin appearance and disappearance to cold hardiness in Hedera helix leaves. Further work (I 16) refuted these results, demonstrating no correlation between hardiness and anthocyanin levels in H.helix. It should be noted, however, that these latter experi- ments were conducted in a greenhouse and herefore the re- sults might not be indicative of field conditions (i.e. natural UVB levels). Parker (30), on the other hand, used field- grown leaf tissues. More recently, Singh et al. (7) studied anthocyanin content and its relevance to cold hardiness of field-grown chick- pea (Cicer arietinum). They concluded there was no association between stem anthocyanins and cold hardiness but did not report these data in the article. Furthermore, because this was not a controlled experiment zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA (e.g.outdoor temperature fluctuations), they would not be able to assess small, but significant, differences in cold hardiness among genetic lines. ------------------------------------------------------------------------------------------------------------------ If anthocyanin was a cause of cold tolerance, it would cause cold tolerance in every plant in which it is present, e.g., my red Canna Intrigue seedlings. I am going to leave both red and green canna seedlings in my zone 5 ground this winter. Do you want to bet that the red ones will survive longer? I bet that both red and green die on the first day that temperatures dip below 32 deg. F..
