Paeonia (Itoh) Prairie Charm

Peony Prairie Charm is a long-flowering cultivar that blooms from May to June. We have known it since 1992 and it is still very attractive. The flowers are yellow with a bit of red in the center of the flower. Long vase life over a week. In 2009, it won the Award of Landscape Merit in America, and it's no wonder.

 How to grow Itoh peonies

 Also called intersectional peonies, Itoh peonies are attractive and easy to grow perennials. Plant Itoh peonies in rich, well-drained soil. Itoh peonies prefer full sun, but will grow in a situation that has some shade for a part of the day. Itoh peonies are sensitive to high levels of nitrogen. When fertilizing Itoh peonies in the spring and summer, be sure to use a fertilizer that contains a low level of nitrogen. Do not fertilize Itoh peonies from late summer to fall. When planting Itoh peonies, the buds needs to be placed in the ground with the red eyes (leaf buds) no more than 5 cm below the soil surface. 

Peonies have decorated European gardens for centuries. Popular species are herbaceous peonies with fully pink, red or white blooms, which come from China and have bigger flowers.

The peculiarity of tree peonies is that the flowers are very large and outstanding, with yellow cultivars also available. Breeders had been trying to cross herbaceous, resistant peonies with more sensitive tree peonies for a long time, aiming to obtain a peony that would have the beautiful flowers of tree peonies and the vigorous growth rate and resistance of herbaceous peonies. Unfortunately, herbaceous and tree peonies are very distant relatives, so they have not been successfully crossed for centuries. This was achieved only in 1948 by the Japanese grower Toichi Itoh. After an enormous effort in which he made about 20,000 crosses, he obtained about 36 plants, 6 of which had yellow flowers. In 1960, these plants were discovered by Louis Smirnow and imported to the United States. The succession of other "Itoh" cultivars with beautiful, large, fragrant flowers and the smooth growth of herbaceous peonies had begun.
