Peonies Facts

Plant Name and Origin

Peonies are easy-to-care flowering plants from the Paeonia genus in the botanical family Paeoniaceae. 

There are a few stories about the name origin of peonies. According to Greek mythology, the botanical name Paeonia originated from the name of Paeon, a known Greek physician of the gods and a former student of Aesculapius.

Aesculapius, the Greek god of medicine and healing, became too envious of Paeon when he cured Hades’ and Ares’ wounds by using peony roots. Aesculapius wanted Paeon dead, but Zeus saved him by transforming him into a peony plant (1).

A different tale tells the origin of the name peony. A gorgeous nymph named Paeonia mesmerized Apollo, the son of Zeus. Because of this, ancient Greek goddess Aphrodite became furious with Paeonia and turned her into a peony plant. 

Another known peony name origin comes from a Chinese myth. Gejin, a peony spirit, fell in love with a man and transformed into a human form. They got married and had two children. When her husband realized that she and the children are not mortal, Gejin brought the children with her back to the spirit world to avoid his rage. She then left two tree peonies, the Gejin’s Purple and the Gejin’s White, for him to remember their two children (1). These two tree peonies remain as popular peony varieties in China up to this day.  

In Germany, peonies are called pfingstrose, which means “Pentecost Rose”.

Brief History of Peony

The peony plant took a significant role during the early Chinese regimen. An imperial symbol, peony flowers were common in the Imperial Palace Gardens and referred to as “Sho Yo,” which means “most beautiful.” 

During the early 8th century, peonies reached Japan, where they have been developed and hybridized to more than 300 cultivars (2). By the 19th century, the beautiful blooms of peony plants further made it to European gardens and revered for their landscape use and medicinal properties. 

Uses of Peonies

Uses of peony plants are not limited to landscaping, gardening, nor floral arrangements. These perennial plants are also famous for their medicinal value.

In China and other countries, the roots, bark, flowers, and seeds of peonies are used to treat a variety of ailments such as night sweats, sores, abdominal pains, fevers, cracked skin, and muscle cramps (3).

Uses of Peonies

General Description and Characteristics

Peonies are low maintenance flowering perennial plants that add beauty and colors in gardens and landscapes, especially from spring to fall. Generally, mature peonies grow about 2 to 7 ft, depending on the type. Some are fragrant, while others are unscented.

The leaves of peonies vary depending on the type and variety of peony. Some peony leaves are glossy without any presence of hair. For some peonies, however, the leaves are dark green with some underside hairs. 

Peony flowers also differ depending on the type and variety. Generally, regardless of flower forms, all peonies have five or more large outer petals and modified stamens at the center (4).  Some peonies exhibit single flowers, while others have semi-double, double, bomb, Japanese, or anemone types. These types are discussed in detail below. 

Types of Peonies

Peonies can be categorized into three groups: tree peonies, herbaceous peonies, and intersectional peonies. 

Tree Peonies

tree peonies

Tree peonies (Paeonia suffruticosa) are deciduous, multi-stemmed woody shrubs (6) that typically grow from 4 to 10 ft in height and spread up to 4 ft. The above-ground stem remains alive throughout the year (7).

Although these perennial plants grow slower than herbaceous peonies, they make excellent borders or accents, especially when planted in groups. They produce large flowers, which usually measure 6 to 8 inches across and are pink to white in color. However, cultivated varieties of tree peonies offer a more extensive range of flower colors, including red, purple, pink, white, and yellow. 

Tree peonies are called Mudan in China (9). 

‘Shimane Sedai’ is one of the most common tree peonies. It delivers attractive rose-pink semi-double blooms that further develop into a double type as the plant grows older. These tree peonies grow up to about 4 ft in height and spread up to 3 ft wide.  

‘Boreas’ is another popular example of tree peonies. Known for its bright red color, boreas peony displays vivid burgundy-red semi-double flowers with ruffled petals. This plant reaches up to 5 ft tall at full maturity in five to eight years after planting. 

Other tree peonies are the Paeonia lutea var. Ludlowii (with large yellow blooms), Duchess of Kent tree peonies, Duchess of Marlborough tree peonies, Reine Elizabeth tree peonies, and Shimanishiki tree peonies. 

Herbaceous Peonies

Unlike tree peonies, herbaceous peonies die to the ground in the fall and re-emerge in the next spring (6). They typically grow up to 2 to 4 ft in height. Herbaceous peonies are also called bush peonies. 

This type of peony is most commonly used in gardens and as cut flowers. Herbaceous peonies offer a wide variety of flower types from single peonies to semi-double, double, bomb, Japanese, and Anemone peonies. The colors also vary, which range from deep red to yellow, white, cream, pink, rose, and more. 

Intersectional or Itoh Peonies

Intersectional peonies

Intersectional peonies are hybrid between tree peonies and herbaceous peonies (6). Also called Itoh peonies, this type was named after Toichi Itoh, who is a Japanese plant breeder that first succeeded crossing a tree peony with an herbaceous type in the 1960s (9). 

Intersectional or Itoh peonies exhibit large flowers and woody stem similar to tree peonies, but they wither to the ground in the fall like herbaceous peonies (8). 

Peony Flower Forms

As mentioned above, peony plants regardless of type can further be categorized depending on their flower forms. They can be single, semi-double, double, anemone, Japanese, and bomb form peonies. 

Single Form Peonies

single form peonies

Some peony flowers have single forms and called single peonies. This kind has one or two rows of at least five prominent outer petals called guards. The guard petals enclose a center of golden pollen-bearing stamens (4). Some examples of single peonies are the Fairy Princess and Imperial Red peonies. 

Semi-Double Form Peonies

semi-double form peonies

Semi-double peonies also have five or more guard petals with a prominent center of pollen-bearing stamens. They have more than one row of guard petals emerging from an exposed flower crown. Semi-double peonies can sometimes look like double peonies, except that they have visible anthers when the flowers are in full bloom (4). 

Double Form Peonies

double form peonies

Double type peonies are the most popular type of peonies for cut flower production (5). They have dense clusters of broad petals that make up large and full blooms. Five or more outer guard petals surround the central petaloids or transformed stamens and stigmas(4).

Bomb Form Peonies

bomb form peonies

Bomb type, on the other hand, is the largest and fullest form of a peony flower. Peonies of this type have prominent petaloids that keep on developing until they nearly obliterate the guard petals. Bomb type peonies give out a globular, pompom-like bloom (5). 

Japanese Form Peonies

Japanese Form Peonies

Japanese peonies are known for their decorative centers of staminodes or thin petaloids. The staminodes are partially transformed stamens that may or may not carry a trace of pollen. 

Anemone Form Peonies

Anemone Form Peonies

The anemone type is a more advanced type of Japanese peonies. Anemone peonies, which are often categorized under the semi-double type, have several rows of guard petals that surround a dense cluster of thin petaloids (4). Unlike Japanese peonies, anemone peonies do not flaunt anthers of any kind. 

‘Cora Louise’ Peony

‘Cora Louise’ Peony

Paeonia ‘Cora Louise’ is an Itoh peony that forms semi-double flowers. This herbaceous perennial produces lightly fragrant white blooms with a burst of dark lavender hue from the center. The leaves are toothed. 

Cora Louise Itoh peonies are vigorous, producing up to 50 flowers per plant in a single season. Fully mature plants grow about 2.5 ft in height and 3.5 ft in width. This variety makes excellent border plants or in containers, mass planting, and urban gardening.

‘Scarlett O’Hara’ Peony

Scarlet O’Hara peonies or Paeonia ‘Scarlett O’Hara’ showcase vivid and fiery scarlet red blooms with contrasting golden yellow anthers at the center.

Culture, Care, and Maintenance

How to Grow Peonies

Peonies are tough perennials. Known as one of the most floriferous garden plants, peonies produce attractive blooms even with minimal care.

Peonies grow best when planted in full sun and loamy, fertile, well-drained soil. They require 6 to 9 hrs of sunlight per day. Partial shade is tolerable as the plants will still produce good foliage, but flower production will be sparse or non-existent (7). Plant them away from other trees and shrubs to maximize moisture absorption from the soil.

When planting peonies, allow ample spacing as these plants have different sizes and growing habits depending on the type. 

Once established, keep peony plants undisturbed as they do not thrive well when replanted (10). 

How to Care for Peonies

Caring for peonies is relatively easy as fully established plants require little maintenance. Although most peony varieties have sturdy stems, other herbaceous types have stems that need extra support in carrying the weight of their flowers. 

Remove flowers as soon as they exhibit signs of withering to avoid the spread of diseases. 

A practice called disbudding produces more abundant blooms. This can be done by removing all side buds and retaining just the terminal bud on each stem (4). 

Pests and Diseases

Like other flowering plants, peonies can also be subjected to pests and diseases that may result in minimal to severe damage to the whole plant if left untreated.

Fungal diseases like Botrytis blight and Phytophthora blight are two of the most common diseases of peonies. Fuzzy, gray spores are often indications of Botrytis blight infestation, while a wet rot is a result of Phytophthora blight. Practicing proper sanitation helps in preventing these diseases. 

Powdery mildew on peonies results in whitish powder on the surfaces of leaves, young stems, and flowers. Infested flowers may be deformed. 

Other common diseases of peonies include Southern blight, mosaic virus, peony ringspot virus, and leaf curl. 

Hoplia beetles, thrips, and scaled insects are the most common insect pests that infest peonies. Though ants frequent peony plants, particularly the buds because of the nectar, they do not cause any harm to the plant. 

Hoplia beetles lay eggs in the soil and cause damage to the flowers’ petals and buds. Thrips also damage the blooms by causing discoloration and disfiguration. These tiny insects also cause bleaching and withering of leaves. 

Peonies can also be infested with scale insects. Symptoms of scale insect infestation include yellowing of leaves, reduced and stunted growth.


Common peonies are generally considered toxic to animals like cats, dogs, and horses. The bark contains a mildly poisonous compound called paeonol that may cause vomiting and diarrhea when consumed in large amounts.
