One of the advantages that you will find within these pages are the differences in bloom periods of peonies.  If you plan your garden/landscape you can easily achieve 7 weeks of blooming.  Note; you will find that some of your favorites overlap 2-3 bloom periods, much of this has to do with the benefit of having sidebuds.  Many of the hybrids may not have sidebuds and therefore won't bloom as long as ones with them.  Take a little time and read the description carefully as we will tell you whether its an extended bloomer or not.
