Dear Jane and all, The ability of some peonies to develop new plants from adventitious roots was a secret long protected by some growers. 'Coral Charm' and most of the other corals have this ability to some degree. I think this trait comes from P. peregrina a bright red species from Italy east to the Balkans and Turkey. This species is one of the easiest and best of the wild peonies for home gardens. Also easy from seed. The flowers in a range of clear bright red/scarlet never open fully, but form a brilliant bowl or cup. I think the species name suggests the 'wandering 'quality of its roots and the ability to pop up here and there. The bright pink variety 'Ludovica' is another notorious adventitious peregrina kin. P. mascula and P. tenuifolia also have this ability and perhaps others. Certain woody peonies also produce active stolons to form bushy multi stemmed ground covers. I have a plant of P. mascula that covers almost a yard across from adventitious or stoloniferous new growths. The adventitious nature of some herbaceous peonies like 'Coral Charm' is a boon for propagators, but some gardeners hate it when a plant is dug out and returns the next year from scraps left behind. Wish I had a source for clusii too. Best 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 +
