Peonies are one of the most beloved and iconic flowers in the world, celebrated for their large, showy blooms and rich cultural significance. Among the various types of peonies, Green Peonies and Itoh Peonies stand out for their unique characteristics. As a supplier of Green Peonies, I'm excited to delve into the differences between these two remarkable varieties to help you better understand their distinct features and make informed choices when it comes to your floral preferences.
Botanical Origins
Green Peonies, also known scientifically as Paeonia suffruticosa var. spontanea, are a type of tree peony. They are native to the mountainous regions of central China, where they have been cultivated for centuries. These peonies are part of the Paeoniaceae family and are known for their woody stems that can persist through the winter. The green color of their petals is a result of a combination of genetic factors and environmental conditions.
On the other hand, Itoh Peonies are a hybrid variety. They are the result of a cross between tree peonies (Paeonia suffruticosa) and herbaceous peonies (Paeonia lactiflora). The first successful Itoh Peony was created by Japanese horticulturist Toichi Itoh in the 1940s. Since then, these hybrids have become increasingly popular due to their unique combination of traits from both parent species. Unlike tree peonies, Itoh Peonies die back to the ground in the winter and regrow each spring.
Appearance
One of the most obvious differences between Green Peonies and Itoh Peonies lies in their appearance.
Flower Color
Green Peonies are famous for their distinctive green - hued petals. The color can range from a pale, almost mint - green to a deeper, more vibrant shade. This unique color is quite rare in the floral world, making Green Peonies a highly sought - after choice for those looking to add a touch of the unusual to their gardens or floral arrangements.
Itoh Peonies, on the other hand, come in a wide variety of colors. They can be found in shades of pink, yellow, orange, red, and even bi - colors. For example, some Itoh Peonies have petals that start off as a deep pink at the base and gradually fade to a lighter shade towards the edges. The Pink Tree Peony showcases the beautiful pink hues that can be found in peonies, and while not an Itoh Peony, it gives an idea of the color range possible in related varieties.
Flower Size and Shape
Green Peony flowers are typically large, with some blooms reaching up to 8 - 10 inches in diameter. They have a classic, full - petaled form, often with a ruffled or frilly appearance. The petals are thick and substantial, giving the flowers a luxurious and elegant look.
Itoh Peonies also produce large flowers, but their shape can vary more widely. Some Itoh Peonies have a semi - double or double form, similar to Green Peonies, while others have a more open, single - petaled structure. The size of Itoh Peony flowers can range from 6 - 10 inches in diameter, depending on the specific cultivar.
Foliage
The foliage of Green Peonies is another distinguishing feature. They have large, deeply lobed leaves that are a rich green color. The leaves are leathery in texture and provide an attractive backdrop for the showy flowers. In the fall, the foliage of Green Peonies may turn shades of yellow, orange, or red, adding an extra layer of visual interest to the plant.
Itoh Peonies have foliage that combines characteristics of both their tree and herbaceous parents. The leaves are typically large, divided, and have a more delicate appearance compared to Green Peonies. They are a bright green color during the growing season and also turn attractive colors in the fall.
Growth Habit
Height and Spread
Green Peonies are tree peonies, which means they have a more upright and woody growth habit. They can reach a height of 3 - 5 feet and have a spread of 3 - 4 feet. Once established, they form a relatively large and stable shrub - like structure in the garden.
Itoh Peonies, being hybrids, have a more compact growth habit compared to tree peonies. They usually grow to a height of 2 - 3 feet and have a spread of 2 - 3 feet as well. This makes them a great choice for smaller gardens or for planting in containers.
Hardiness
Green Peonies are generally hardy in USDA zones 4 - 9. They can tolerate cold winters, but in areas with extremely cold temperatures, some protection may be needed. They prefer a location with full sun to partial shade and well - drained soil.
Itoh Peonies are also quite hardy and can thrive in USDA zones 4 - 9. They are more adaptable to different soil conditions compared to Green Peonies and can tolerate a wider range of pH levels. They also have good resistance to pests and diseases, making them a relatively low - maintenance option for gardeners.
Bloom Time
Green Peonies typically bloom in late spring to early summer, usually a bit earlier than Itoh Peonies. The exact bloom time can vary depending on the specific cultivar and the local climate. Their blooms last for about 7 - 10 days, providing a short but spectacular display of color in the garden.


Itoh Peonies bloom a bit later, usually in mid - to late - summer. Their bloom period can be slightly longer than that of Green Peonies, lasting up to 10 - 14 days. This extended bloom time makes them a great choice for adding color to the garden when other flowers may be starting to fade.
Cultural Significance
In Chinese culture, Green Peonies hold a special place. They are often associated with wealth, honor, and prosperity. They are frequently used in traditional Chinese festivals and ceremonies, and their image can be found in various forms of art, including paintings and embroidery.
Itoh Peonies, while not having the same long - standing cultural significance as Green Peonies in China, have gained popularity around the world for their beauty and versatility. They are often used in modern floral arrangements and are a favorite among gardeners who appreciate their unique combination of traits.
Uses in Floral Arrangements
Green Peonies are a stunning addition to any floral arrangement. Their unique color and large, showy blooms make them a focal point. They can be paired with other flowers such as roses, lilies, or hydrangeas to create a luxurious and eye - catching bouquet. Their long stems also make them suitable for tall, elegant arrangements.
Itoh Peonies are also highly valued in the floral industry. Their wide range of colors and long - lasting blooms make them a versatile choice for different types of arrangements. They can be used in both formal and informal settings and can be combined with a variety of other flowers and foliage to create beautiful and unique designs.
