These are the future of peonies. Although they are expensive (because
they are very new) these, once known as Itoh peonies, are crosses between tree peonies and herbaceous peonies
bring the best of both to the plant. They grow into large clumps, with
woody stems that can be cut back like herbaceous peonies. The flowers
are large, like a tree peony, held upright above a broad clump of large,
very handsome foliage, which does not deteriorate before it drops (unlike
some herbaceous peonies).
They should be planted and cultivated like herbaceous peonies. All grow to around 3ft (90cm) in height. Flowering season
starts with the large double peonies, which is early/mid June and continues
for about 3 weeks.
They look equally at home in a border with perennials or shrubs. Once
planted they do not need any further attention for years.
Intersectional peonies flower durng June, and (with us) stay in bloom
longer than either herbaceous or tree peonies. In height they grow from
to around 90cm (3ft) high.
GROWING AND MAINTAINING
Planting
Peonies need a well-drained soil. They can cope with a little shade
during the day, but being plants of the open ground they prefer full
sun. They need to be planted with their roots no deeper than 1in (2cm)
below the soil. If they are planted deeper they may refuse to flower.
Fertilising
A little very well rotted manure can be placed around the dormant plant
in winter if the ground is very deprived of nutrients, but generally
they can be left undisturbed for many years.
Moving
Contrary to what has been written in the past, peonies do not mind being
moved - especially if they are not divided.
Disease
As yet we have found no evidence of any diseases.
Failure to flower
We have found no problems with intersectionals when it comes to lack
of flowers. Indeed they tend to be less shy than other types of flowers
to produce blooms, which are generally produced in the first year after
planting. These varietis are increditbly floriferous.
