The story of the Rose Clean Stock Program starts back in the 1960s with Dr. George Nyland, a plant pathologist and advocate of virus-tested planting stock. He began using heat therapy to propagate rose material free of rose mosaic disease and created a collection of clean rose stock. The collection was revamped in the 1990s by our current Head of Production, Mike Cunningham, and serves as a source of clean budwood for nurseries and growers across the United States.
The eight acre collection is the largest public collection of virus-tested roses in the United States. That eight acres holds seven understock and over 500 scion cultivars! You can find a list of all the varieties on the FPS website under the Rose tab.
For more information, please see the attached agenda or visit the event website.
Free mini floribunda roses will be handed out to the first 250 attendees!
