The U.S. Botanical Garden is offering a free tour of its rose garden. Join PRS members and others on May 11, 2018.
Beautiful, versatile, and timeless, the rose is the U.S. national floral emblem. Opened in 2006, the USBG Rose Garden is a formal garden space dedicated to growing the rose without the use of fungicides or insecticides. The roses growing in the garden have been selected from many classes of roses grown today, both "Old Roses" and "Modern Roses." Learn about brand-new 21st-century roses that have been hybridized specifically for disease resistance. They will make your rose garden "greener" and so much easier to maintain. Which rose did Teddy Roosevelt demand for his lapel? Which rose is so persistent and resilient that it is perfectly happy in today's Manhattan? Come stroll the paths, hear the roses' stories, and see our beautiful rose garden! Please note: This tour is held outdoors. We suggest wearing sunscreen and protective clothing and bringing water. The tour is canceled if it rains or during times of extreme heat (head index of 95 degrees or higher/Code Red weather alert).

This three-part afternoon program featured:

Making Beautiful Container Plantings with Roses

Rose Rosette Disease: An Update
We have all seen the unsightly stands of Knockout Roses planted in median strips and occasionally, our home gardens, that have strange, deformed stem and leaf configurations. This anomaly, known as Rose Rosette Disease, attacks our hybrid teas, climbers, shrubs and all other types of roses. Dr. Mark Windham spoke at the U.S. National Arboretum. He is a leading researcher on Rose Rosette and provided an update on this disease that is a threat to the gardens of all rose lovers.
DR. MARK WINDHAM discussed current research being conducted on Rose Rosette Disease (RRD), as well as the latest research identifying disease resistant varieties. The American Rose Society Research Endowment Trust identifies Rose Rosette Disease as the greatest threat to the future of commercial and recreational growth, and the enjoyment of roses. In 2012, ARS selected Dr. Windham to head a three-year study about the management of RRD. The objectives were to determine how rosarians manage RRD in their gardens and identify best practices
for RRD, besides eliminating plants with symptoms. Dr. Windham also believes that roses have lost popularity due to growing public aversion to the regular use of pesticides in home gardens and has therefore been developing a list of roses that homeowners can successfully grow without reliance on chemical control tactics. Rose Rosette will continue to be a threat to our home gardens for years to come. In a grant fully funded by the USDA National Institute of Food and Agriculture’s Specialty Crop Research Initiative, Dr. Windham is included in a group of 18 scientists concerned with Rose Rosette research (housed at Texas A & M), that continues to lead research on Rose Rosette Disease.
