This has been a strange Spring for me. Usually, the singles bloom first by about a few days then the doubles. This year, the doubles bloomed first and the singles are just straggling along, many stems with no buds. To answer your question, the combined normal bloom cycle would be about 3 weeks until the flowers die. We have about 10 days of warm weather forecasted so all the remaining peonies should show some rapid growth. Next bloomers should be Early Scout and Roselette.
