Red Peonies
Ruth Clay (Kelsey 1935). A double, early, midseason variety of great charm. When we visited Mr. Kelsey's gardens we were greatly impressed with this fine red and our enthusiasm was joined by other peony enthusiasts, so we are not alone in pronouncing this a fine red. A rich living red that is different. We hope to see it displayed at our shows this year.
