Rare Single Japanese Peonies
The so-called Japanese Peonies are those which have one or two rows of petals and centers of stamens much thickened. These are almost devoid of pollen and oftentimes make a thick cushion of golden yellow. The effect is very beautiful and distinct and they continue to bloom throughout the Peony season. Although strong growers they propagate slowly and the stocks are usually limited.
Isani Gidui 9.3, tall strong stems, rounded petals of pure white with a thick cushions of golden stamens. We consider this the best white which we have ever seen, but our stock is very limited and for this year it is not for sale.
