Upcoming PRS Events

Watch for announcements for fall 2017 events, and mark your calendar now for:

Sunday March 18, 2018, when PRS will present the very latest research and developments on Rose Rosette Disease, along with Recommended Rose Varieties for Disease Resistance. Featured speakers will include Dr. Mark Windham, Professor of Entomology and Plant Pathology at the University of Tennessee, Knoxville.

The American Rose Society Research Endowment Trust selected Dr. Windham to head a three-year study, beginning in 2012, concerning the management of Rose Rosette Disease. The objectives were to determine 1) how rosarians can manage RRD in their gardens, and 2) what best management practices for RRD can be developed, other than eliminating plants with symptoms.  The Trustees have identified Rose Rosette Disease as the greatest threat to the future of commercial and recreational growth and enjoyment of roses.

Dr. Windham believes that “Roses remain the ‘Cadillac’ of the ornamental flowering plant world, but that the public is now demanding more disease-resistant rose varieties.  In conjunction with the rose industry, he has screened hybrid tea and floribunda roses for resistance to black spot and powdery mildew. His goal has been to generate a list of roses that homeowners can grow successfully without reliance on chemical control tactics.

This promises to be an interesting and informative program. Location to be announced.

Have you ever wanted to grow beautiful roses, but thought that they were too difficult? Attendees at this Symposium learned that disease-resistant roses are the answer. These gorgeous, easy care roses will thrive in the DC Metropolitan area. If you can grow weeds, you can grow these roses!

She has served on their Board of Directors for almost 20 years and is a Life Member and Steward of the American Rose Society.

When was the last time you had an opportunity to learn from a true expert about any and everything relating to roses and other flowers? PRS members were fortunate enough to do just that on January 22, 2017, when Jeff King and Jeffery Serafini from Potomac Floral Wholesale presented to our group. They brought with them hundreds of stems of their most beautiful rose varieties for us to examine and enjoy, a sight for sore eyes for rose lovers in the middle of winter!

Potomac Floral.
A full house was on hand to hear from Potomac Floral.

With over 30 years in the flower business, Mr. Serafini, Purchasing Manager at Potomac Floral, is a veritable encyclopedia when it comes to roses. He patiently answered all of our questions, incorporating many interesting anecdotes gained from his vast experience.

Jeff King, Public Relations and Sales Manager, invited us to visit their warehouse in Silver Spring to see all of the many rose varieties they have to offer. Everyone enjoyed Mr. Serafini's outstanding presentation, and we look forward to putting all of his excellent tips to use this season, to better enjoy the beauty of roses in our homes and in our gardens.

Thank you, Potomac Floral!
