Types of Peonies: Different Categories and Varieties to Choose

Sharing is caring!

Peonies are a beautiful and popular type of flower that come in many different varieties. While they may all look similar at first glance, there are actually several different varieties of peonies, each with its own distinct appearance.

In this blog post, we’ll introduce you to some of the most popular types of peony blooms and explain what sets them apart.

Categories of Peonies

The different types of peonies can be broadly classified into three main categories within the Paeonia genus: herbaceous peonies, tree peonies, and Itoh peonies. 

Within these categories, there is a great deal of variation in terms of size, shape, and color. Let’s take a closer look at each type before you learn how to grow peony flowers.

Herbaceous Peonies

The first type of peony we’ll be discussing is the herbaceous peony. Herbaceous peonies are characterized by their lush green leaves and big, showy blooms. They tend to be some of the most deer-resistant species.

Herbaceous peonies die to the ground in the fall and re-emerge in the next spring. The peonies season usually starts from late spring to early summer.

Herbaceous peonies are also called bush peonies. 

This type of fragrant peony typically grows to be about 2-3 feet tall and have a bushier growth habit than other peony types. 

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 peonies, double, bomb, Japanese, and Anemone peonies. The colors also vary, which range from deep red to yellow, white, cream, pink, rose, and more. 

Tree Peonies 

Tree peonies (Paeonia suffruticosa) are deciduous, multi-stemmed woody shrubs 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.

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. 

Intersectional Peonies

Intersectional peonies are hybrid between tree peonies and herbaceous peonies. 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.

Intersectional or Itoh peonies exhibit large flowers and woody stems similar to tree peonies, but they wither to the ground in the fall like herbaceous peonies. This is why when choosing companion plants for peonies, they need to complement your garden when your peony plants go into dormancy.

Different 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

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. Some examples of single peonies are the Fairy Princess and Imperial Red 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 multiple rows of guard petals protruding from an exposed flower crown. A semi double flower can sometimes look like a double peony, except that its anthers are visible when the flowers are fully bloomed.

Double Form Peonies

Double type peonies are the most popular type of peonies for cut flower production. 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.

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. 

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

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. Unlike Japanese peonies, anemone peonies do not flaunt anthers of any kind. 

Types of Herbaceous Peonies
