Peonies have 3 different varieties: herbaceous, tree, and itoh. However, Tree Peonies are a popular choice for their large beautiful blooms and deciduous, woody stems.
Tree Peonies are a fragrant, hardy, shrub sized plant with large vibrant blooms and dark green foliage. Unlike herbaceous peonies, tree peonies’ stems don’t die back into the ground. Their woody stems remain all year, but their foliage is lost in the fall. The plant flowers from late spring to early summer and shows off its single or double petals, with the blooms sometimes reaching 10 inches in diameter. One plant alone can have over 50 blooms. Blooms come in a variety of colors including white, pink, red, purple, yellow, or any variation of multicolors.
What are Tree Peonies?
Originally from China, Tree Peonies have found themselves across the globe. Thousands of years ago, they were used for their medicinal properties. In ancient China and Europe, people would use dried roots to help treat involuntary muscle spasms and various other nervous system problems.
Chinese Buddhist monks are credited for taking the Tree Peony to Japan, where gardeners further developed the plant and created different varieties of it. So now, the Tree Peony has many different varieties, each depending on the nation from which it originated.
The Chinese variation of Tree Peonies may be more difficult to find as well as being more difficult to grow.
Tree Peonies belong to the Paeoniaceae family and the Paeonia genus. Its botanical name is Paeonia suffruticosa.
How to Grow Tree Peonies
Where it Grows
The Tree Peony grows best outside in the garden, lining a walkway, and for creating interest. It can also grow in containers or pots, but it may need more attention.
Given the name of this plant, Tree Peonies are indeed shrub sized, reaching an average 5 feet in height and width. Occasionally, one of these plants can reach 10 feet in height. It takes 10 years for this plant to reach maturity. One of these plants can live up to 100 years if it’s properly cared for! Sometimes it can take up to 3 years for the plant to show any signs of blooms.
Only prune this plant to be shaped or if it has any dead branches on it.
Growing Zones and Weather Conditions
USDA Plant Hardiness Zones 4-8 are where the Tree Peony lives best. Sometimes it can stand the temperatures of zone 3, but that’s not guaranteed. Since they remain dormant during the winter months, they do well in cold winter climates as long as they have warm summers.
Putting mulch around the wintered root system will help keep it alive during the cold months. It’s best for the plants if they’re protected from harsh winds.
Type of Soil
Tree Peonies need well-draining, fertile soil that is slightly alkaline in nature. Placing bone meal in the soil twice a year (spring and fall) will help the Peony with supplemental nutrition. Soil with organic matter in its composition aids the Tree Peony.
Light, Fertilization, and Watering
It grows best in the full sun, but it will need shaded protection from the hot afternoon sun. If it receives too much sun, it can cause the beautiful blooms to wither and die.
Occasional fertilization with manure or compost will boost plant health and flower growth. Also, fertilizing it with a general-purpose mix, higher in phosphorus than potassium or nitrogen, will increase the overall health.
It’s important to water these plants at the base of their root system, not from the top of the plant. They can be susceptible to root rot, so water accordingly. A deep soak is helpful, and the soil should dry about 4 inches deep before another watering. Once it has been established, it’s very drought tolerant.
Growing Tree Peonies Step by Step
It’s easiest to grow these peonies from root balls or seedling plants in containers. The plants will be dormant during the winter, so once the early spring arrives:
- Select a spot in the garden that will receive an adequate amount of sunlight (5-6 hours each day) and has well-draining, fertile soil. Make sure that it won’t be competing with other plants that have large root systems.
- Dig a hole for the plant about 12 inches deep and wide then place the plant in it
- Water it well (but don’t overwater) so it can begin growing its underground root system.
- It may take a few years for the plant to produce blooms, but it’s well worth it!
