Garden Impatiens Are Back... Without the Risk! By Tom Castronovo Executive Editor To bring disease-resistant Impatiens back to gardens everywhere, it took a dedicated team and collaboration of plant breeders and researchers at PanAmerican Seed. Through their hard work, the next generation of Impatiens walleriana is ready to take the summer stage. Since 2011, Impatiens downy mildew (IDM) has decimated Impatiens beds across the globe. IDM is caused by a host-specific water mold, Plasmopara obducens. When present, and environmental conditions are met (high humidity and cool night temperatures), the disease can spread rapidly, resulting in flower drop and eventually plant collapse – a loss of Impatiens in your garden! Both airborne and overwintering spores meant this popular shade garden flower couldn’t be grown with confidence because of the threat of disease. At first, gardeners planted alternatives for shade color: Begonia, Torenia, Coleus, as well as New Guinea Impatiens, which are not susceptible to the disease. But nothing could take the place of the traditional Impatiens walleriana garden fill, color range and performance. The team at PanAmerican Seed began searching for a disease-resistant Impatiens soon after IDM took hold. Collaborating on the project was a team in the Netherlands, led by breeder Ruud Brinkkemper, and a crew in the United States consisting of product manager Lisa Lacy, plant pathologist Dr. Colleen Warfield, and many others. During numerous plant trials and tests, a selection of Impatiens that

displayed high resistance to Plasmopara obducens was discovered and Beacon Impatiens was born. Available in six colors and two mixes, you can now fill baskets, window boxes, and shade landscapes with confidence. Since the widespread outbreak of Impatiens downy mildew, greenhouse producers have lost revenue due to plant losses during production and poor performance of Impatiens in landscape beds and planters. Many businesses hesitated to stock this key shade-loving flower. Now, through devoted breeding efforts and collaboration that spanned the globe, PanAmerican Seed offers Impatiens downy mildew-resistant Beacon, and with it the opportunity to bring back into production this well-known, in-demand, easy-to-grow and versatile product for increased sales without the risk. “Beacon Impatiens is truly an effort years in the making. Since the early days of the devastating disease, greenhouses have been waiting for the chance to bring Impatiens back,” says Anne Leventry, President of PanAmerican Seed. “To bring Beacon to market with proven high resistance to Impatiens downy mildew, we are confident that our greenhouse customers, retailers and gardeners alike will also have the confidence to grow garden Impatiens once more.” Beacon Impatiens had its official debut at the California Spring Trials in Santa Paula. The California Spring Trials is an annual weeklong event held at various locations throughout the state. The event is a launching ground for some of the newest plant varieties, signage and packaging products, and merchandising programs and concepts. (Cont. on Page 16)
