The plant I received as ‘Defender’ is shown on the right but I realized some time ago that neither the flower color nor the filaments correspond to the description by Silvia Saunders. A reader has now come to my rescue with photos of his plant. It appears to be match the description. Stay tuned for further information.
I also noted that a bloom matching my incorrect one was shown at the recent American Peony Society’s flower show in Ann Arbor, Michigan and also labeled as ‘Defender’, so be sure to check your plant to see if you have the right version.
