Peony flowers are absolute charmers. With their sensual fragrance and beautiful blossoms, who wouldn’t want them in their garden? These plants start to bloom in late spring and into the early summer, which means the flowering season lasts from April to June. Although that’s a range of 6–8 weeks, individual blooms only last for 7–10 days.

While peonies have been used for decorative purposes for several centuries, most gardeners still know a little about them.

Keep reading to understand the factors that determine the blooming of peonies and how you can maintain a continuous show of the beautiful blooms in your garden.

About Peonies

Peonies are a type of perennial flower with over 30 species. Their flowers are typically lush, and their leaves are elegant and rounded, making them a fantastic foliage plant. Their blooms could either be pink, yellow, orange, red, purple, white, or multi-colored.

Despite being able to live for over 100 years, these glorious plants have a very short but satisfying blooming season. They are most noticeable in gardens and flower beds in May, meaning if you plant and care for them accordingly, you’ll decorate your banquets with peony flowers during Mother’s Day or Memorial Day.

How Long Until Your Peonies Bloom?

Ideally, peonies should take between 2–3 years to start blooming. Being an ornamental flower, they should flower in spring, but there are a number of factors that could alter their blooming season:

1. Plant Species

As we mentioned, there are over 30 different species of peonies. The growing and flowering behaviors vary from one cultivar to another, with the herbaceous types taking the shortest time to bloom.

2. Variety

Peonies aren’t only classified according to their species but by their type as well. There are early-season, mid-season, and late-season varieties.  If you visit any flower shop, you’ll be guided through the best variety of choices for your garden.

  • Early-Season: They start to bloom early in spring, splashing your flower beds with an array of colors and fragrances. They are perfect for gardeners who live in areas that experience mild winter and early summer heat. Examples of early-season peonies include Coral Sunset, Coral Charm, Albert Niva, Pink Hawaiian, and Alertie.
  • Mid-Season: These offer a selection of vibrant and fascinating colors, forms, and fragrances a couple of weeks after early-season peonies bloom. Some examples of this variety include Kansas, Edulis Superba, Big Ben, and Benjamin Franklin.
  • Late-Season: If you live in a place where summer heat comes in July, late-season peonies would be perfect for your garden. This variety is made up of gardeners’ most beloved peony species, such as Bowl of Beauty, Karl Rosenfeld, Dr. Alexander Fleming, and Felix Crousse.

3. Planting Time

Generally, you should plant your peonies in autumn when the soil is still warm. Your plants will consequently settle in and develop strong roots ahead of weeds. Planting them in spring will not only delay the blooming season but also weaken their strength, so, ensure you figure out the timeliest season for planting.

4. Region

While they do outstandingly well in hardiness zones 2–8, the peonies in your garden can bloom early or late depending on which part of the country you live in. In places like California and Texas, tree peonies bloom from mid-February to late March, whereas herbaceous peonies start blooming at the start of April.

In Michigan, Massachusetts, and other zones of similar hardiness, tree peonies bloom from late April to mid-May while herbaceous varieties begin to bloom from mid-May to June.


5. Routine Care Practices

In general, it is safe to say that peonies require minimal care because they are highly resistant to pests and diseases. However, when they are still young, they require frequent watering and weeding to produce brightly-colored flowers. Failure to water them will lead to stunted growth and slightly dull blooms.

No, peonies don’t bloom throughout all summer. Each individual peony bloom lasts for 7–10 days. But since all the buds in a plant do not open at once, the blooms can last up to 3 weeks. If you are wondering how to extend the blooming season to last throughout summer, our next section answers your questions.

How to Extend the Blooming Season of Peonies

1. Disbudding

The first thing you need to do to keep your peonies blooming throughout summer is to disbud them at the appropriate time. Disbudding is a form of pruning whereby you cut back the strong leaf bud when the flowers start to show signs of fading. The most ideal time for disbudding is immediately after fall as the plants will end up with a perfect shape.

Also, it’s worth knowing that cutting your peonies too early or too late may harm them. Frostbite is fond of attacking peonies that are disbudded late. On the other hand, disbudding them too early can make your peonies appear stocky while also producing tiny blooms.

When cutting, ensure you clip the stem as nearest to the ground as possible. Cut the big buds precisely at the tip of the stems.


2. Provide Sufficient Sunlight

Besides their magnificent blooms, peonies are widely loved by gardeners because they require only a little care, thanks to their toughness against diseases. However, peonies can easily become susceptible to botrytis (also known as gray mold) when they are grown in a cool and damp environment. The threat is even bigger if they have been grown in a sunlight-limiting environment.

Botrytis has been known not to kill peony plants but weaken them with time, finally reducing their population in your garden. They also shorten the blooming season drastically. The fact that the disease can attack your peonies without showing any infection signs for about a year makes it worse. That’s why it’s essential to ensure your peonies receive sufficient sunlight.

Take time to transplant crowded plants and remove all weeds growing around them. If the garden is damp, you must drain the soil to minimize the chances of infection. Also, if you decide to plant peonies against a fence or building, ensure it’s on the side that receives enough sunlight.

3. Follow All Staking Requirements

Some peonies have heavy tops that might flop by if not staked. For that reason, you should consider staking them to provide the best conditions required for optimum blooming. However, most peony species may not require staking, as they can naturally maintain an upright shape.


4. Plant Different Varieties and Species

Since peonies can be classified into early, mid, and late seasons, you can plant all of them in your garden within a few weeks of proficient blooming. By doing so, you will continuously enjoy peony blooms from early spring to the end of summer.
