Peonies are hardy perennials, valued for their form, variety of color and ease of cultivation. Colors range from white, cream or yellow, to pink, rose and brilliant scarlet. Attractive foliage remains after spring blooming, which makes the peony a fine accent plant for the shrub border. If planted close together, peonies can also form a striking hedge to separate the lawn from a driveway or path.
Peonies look good against around foundations but may need additional watering if this location is dry. Plant peonies at least two feet away from the wall to allow for full growth.

How to Cultivate Peony Plants
Peonies need moist, rich soil in full sunlight or light shade. Dig a planting hole of 8 to 10 inches deep, three feet away from other plants, placing the eyes (buds) no more than two inches below the surface. Peonies set deeper than this may produce lush foliage but fail to bloom satisfactorily.
If your soil is poor, dig a hole two feet deep and two feet wide, filling with good-quality topsoil before planting the peony root.
Peonies are heavy feeders. Work two tablespoons of 5-10-5 fertilizer into the soil around each plant in fall or early spring. Alternatively, amend the soil around the plant by applying one to two inches of well-rotted manure or compost taking care to keep the manure well away from the plant stems.
How to Stake Peonies and Cut Flowers
Taller peony varieties and those with double flowers usually need staking. Wire hoops attached to three or four stakes should be set out in early spring, to circle and support the plant as it grows larger. Commercial peony stakes are also readily available.
Cut peony blooms as soon as the outer petals unfold for use in bouquets. Place stems in a container of water as soon as they are cut, then snip the stems again under water to promote long-lasting cut flowers.
As flowering comes to an end, remove any spent blossoms by cutting the stem level with the plant’s foliage.
Types of Peonies
According to Rodale’s Illustrated Encyclopedia of Perennials, most garden peonies are hybrids of Paeonia officinalis and P.lactifora which can be grouped into four categories by the shape of their flowers.
Single peonies have a ring of 5 or more petals with a central ring of stamens…Japanese peonies have a ring of petals around a central cluster of modified stamens that are narrow and flat and bear no pollen….Semidouble peonies have several rings of petals around visible stamens. Double peonies have many concentric rings of petals and no visible stamens.

How to Divide Peonies:
– From Popular Peonies by the North Dakota State University Agriculture and University Extension
When old, established peony clumps become too crowded, flowering may be reduced and the roots should be divided. In September, cut the stems near ground level and dig the roots carefully with a spading fork. Shake the roots to remove loose soil and then wash off most of the soil. Washing the soil away helps you to locate natural crown cleavage areas so that less of the fleshy roots are lost while dividing the clumps. Each division should have three to five healthy eyes (buds) attached to three or four thick roots.
A husky division of an old peony plant should not be expected to flower the first year after planting. In fact, it is advisable to nip off any flower buds that appear the first year to permit the plant to develop its root system during the first year of growth. During the second year your plants may be permitted to flower. By the third and fourth years, the plants should give excellent blooms.
Healthy peonies in fertile soil may bloom for as long as 50 years.
