I spoke with Harald almost three years ago and he explained that he would need to ship at least ten roots to the US in order for it to make economic sense. Phyto inspections and shipping costs a fortune. Warmerdam Peonies was offering Quitzin and Triphena Parkin but were pricey and there again overseas shipping costs. A&D peonies also carried Quitzin. As Harald & Ruud explained it to me, we have to be patient and they will arrive here gradually.
