Dear friends, Named tree peonies are usually propagated by division or grafting. Division is obvious. Gratfing less so. Until my book (in progress) on the topic is out, the basics are covered in a American Peony Society "Handbook" for about $5. Contact them via the address given at their web site. Graft in Aug or Sept. Seeds will NOT produce an identical plant. Starting seeds is covered in some detail in 'The Genus Paeonia" by Halda and Waddick. Plant seeds as soon as ripe (August) outdoors in a protected spot. They need a few months of warm weather before winter to germinate next spring. Storage only prolongs germination one or more years. Easy this way, fussy if not. Good luck. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd. Kansas City Missouri 64152-2711 USA Ph. 816-746-1949 Zone 5 Record low -23F Summer 100F +
