Run for the Roses Pre-Race Happy Hour Rose Talk
The Kentucky Derby has grown into an American cultural event unlike any other since its inaugural running in 1875, and the race’s association with red roses has a history as rich as The Derby itself. It all started in 1883, when New York socialite Evander Berry Wall presented red roses to ladies at a fashionable Louisville post-Derby party that was attended by Churchill Downs founder and President, Col. Meriwether Lewis Clark. The roses were such a sensation that Clark adopted red hybrid tea roses as the official flowers of the Kentucky Derby. Later, Clark began to use red roses to decorate the post-Derby party, and by the 1890’s the red roses were also being used in the post-race presentations, first as a bouquet for the winning jockey, then as a garland for the winning horse. In 1925, then-sportswriter Bill Curom, who later went on to be President of Churchill Downs, coined the term “Run for the Roses”, and that name is now synonymous with the all-important first leg of horse racing’s Triple Crown.
RED ROSES was the theme for this year’s PRS Happy Hour Rose Talk. Carol Edwards showed 10 disease-resistant roses for our area and we all compared notes on how they do in our gardens. We chatted about the celebratory drinks including the traditional mint julep, a red rose inspired cocktail by Carol and a Pimm by Kathy Jentz. We also shared our hats. Prizes went to Kathy Jentz for best rose, Inez Austin for best hat, and Carol Edwards for best cocktail. Prizes were some of the best rose books, donated by a former member of PRS.
Floral Design with Roses
A participatory group created gorgeous arrangements to cheer the life of someone who has been especially helpful or gracious to you during the pandemic or for their own enjoyment.
Sachi of Sachi Rose Design led a beginner’s workshop. Sachi walked us through the creation of a lush, garden-style centerpiece. We learned how to “condition” each stem to designing in vases. Download the DIY floral design guide.
About Sachi: In 2008, Sachi graduated from The School of the Art Institute of Chicago with a BFA in painting and ended up moving back to LA to pursue a career as a starving artist. That didn't work out because Sachi has an awesome appetite, so she decided to get a side job at a sweet little flower shop called Botany. Flowers quickly became her medium of choice as she went on to become the head designer, and finally discovered her calling.
Eventually Sachi moved to Brooklyn and designed for a handful of New York's top florists until 2013, when she decided to venture out on her own. Starting out as a one-woman-show fulfilling small orders soon turned into designing large scale events all over the country.
Pruning Demonstration and Volunteer Opportunity
On two consecutive Sundays in March, PRS members learned rose pruning techniques from experts and helped care for the more than 1000 roses at the Brookside Rose Gardens. Newcomers were paired with experienced pruners for 1-on-1 teaching. Participants had a chance to learn and put into practice best pruning techniques while providing hands-on help to one of the most important rose gardens in the Washington DC area.

Her presentation focused on the three tenants of of healthy roses-selecting the right rose, planting in the right place, and controlling disease and pests. She discussed the many elements of Integrated Pest Management practices in public rose gardens. Ms. Fetzer discussed rose midge, sawfly, thrips, mites, black spot, virus, powdery mildew, nutrients, mulch, biological controls and chemical control.
Roses, Garlic and More, A Love Story

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.
