Description
Peonies are one of the most beautiful and fragrant flowers you can grow in your garden. They come in a variety of colors including pink, white, and red.
These gorgeous flowers are actually a member of the rose family, known as Paeoniaceae. They're native to China and other parts of Asia.
Peonies are perennials, which means they come back year after year, and can grow quite large, with some varieties reaching up to 4 feet tall and 3 feet wide. They have thick, fleshy roots that help them survive the winter.
Peonies typically bloom in late spring, around May or June, and can produce hundreds of flowers on a single stem. They're also a great choice for cut flower arrangements because they're so long-lasting.

Herbaceous
Herbaceous peonies are a type of peony that die to the ground in late fall and emerge again in spring.
Most classic garden peonies are herbaceous, with about 30 species available. The most common species is Paeonia lactiflora, which is native to China.
Herbaceous peonies tend to be around 40" tall and produce multiple buds on each stem. They're extremely cold-hardy, able to tolerate temperatures as low as -40°F.
These plants require a long winter dormancy – at least six weeks at temperatures that stay consistently below 40-45°F. This makes them less suitable for the south.
Hybrid herbaceous peonies are available in a wide range of heights, colors, and bloom times. They typically have stronger stems and fewer side buds than P. lactiflora.
Some hybrid herbaceous peony cultivars can grow well in warm climates, including America, Blaze, and Coral Charm. Heat tolerance varies by cultivar, depending on the species combined to create the hybrid.
Growing Conditions
Growing peonies in zone 7 requires careful consideration of their specific needs. Peonies need a location with 6 to 8 hours of sunlight a day.
The right soil is also crucial for peonies to thrive. Planting them in well-draining soil is essential, as they don't like wet soil or soggy roots.
Suggestion: What Kind of Soil Do Peonies like
Sun Perennials
Sun perennials are a great choice for any garden, attracting pollinators and producing beautiful blooms for years to come.
These plants thrive in full sun, receiving about 6-8 hours of direct sunlight per day. Without it, they grow poorly and their blooms are less vibrant.
Roses, peonies, and irises are just a few examples of sun-loving perennials that will perform well in your garden.
Daylilies, hibiscus, coneflowers, and asters are also excellent options for sun perennials, providing a long-lasting display of color and texture.
Sun perennials can grow poorly and produce few blooms if they don't receive enough sunlight.

Best Soil for Flowers
Growing beautiful flowers requires the right soil conditions. Peonies, for example, don't like wet soil or soggy roots, so it's essential to plant them in well-draining soil.
You can amend the soil with organic matter like Bloom or Leafgro to give peonies a good start. This will help them grow and thrive.
Adding the right amount of BioTone from Espoma can also maximize growth and health.
Where To Plant
To plant peonies successfully, you'll want to choose a location with plenty of sunlight - at least 6 to 8 hours a day.

Good drainage is also essential, as peonies don't like wet feet.
Peonies need room to spread out, so pick a spot that's far away from large trees and shrubs, which can compete with their roots for water and nutrients.
Transplanting established peony plants can be difficult or even impossible due to their deep roots.
Planting and Care
To plant peonies successfully, you need a location with 6 to 8 hours of sunlight a day. This will give them the energy they need to thrive.
Good drainage is also crucial, as peony plants don't like wet feet. Established plants have deep roots that make transplanting difficult or even impossible, so choose a spot that's right from the start.
Plant peonies far away from large trees and shrubs to avoid root competition, as recommended by the experts from the University of Michigan's Peony Garden at the Nichols Arboretum.

Watering
Peonies are not thirsty plants, so it's essential to be mindful of overwatering. Overwatering can lead to problems.
Water your peony bush in spring if you go more than two weeks without rain. Begin with excellent drainage to prevent waterlogged soil.
Water your peony bush weekly, deeply, throughout the dry summer months. Provide one inch of water at each watering.
Continue watering your peony bush after flowering to ensure vigorous plants the following year. This will promote healthy growth and blooming.
There's no need to water your peony bush once it has gone dormant.

How To Plant
To plant peonies successfully, you need to pick the right spot. This means finding a location with 6 to 8 hours of sunlight a day and good drainage.
The experts from the University of Michigan's Peony Garden recommend planting peonies far away from large trees and shrubs, as they don't like to have root competition.
To determine how deep to plant your peony, consider the type you've purchased. Herbaceous peonies should be planted with their "eyes" (next year's buds) ½ inch below the soil surface in warmer zones, or 2 inches below in cooler zones.

Tree peonies, on the other hand, require a deeper planting. Dig a hole that's 2 feet deep and 1 foot wide, and amend the backfill with organic matter. Plant the graft 4 to 6 inches below ground level, so that the "nurse" herbaceous peony rootstock will die away.
Intersectional peonies can be planted just below the soil surface, 1/2 inch deep in warm zones, or 1.5 inches in cooler zones.
Here's a quick reference guide to help you remember the planting depths for each type of peony:
Should I Mulch?
Mulching can be a game-changer for peonies, especially in cold climates. In these areas, a loose winter mulching with organic matter like pine needles or shredded bark can benefit the plants.
Keep mulch a few inches away from the base of the plant to prevent rot and other issues. This simple trick can make a big difference in the health of your peonies.
For tree peonies, winter protection is especially important in Zone 4 and colder parts of Zone 5. A 3 to 4 inch layer of mulch, wrapped in burlap and pulled aside in the spring, can be a lifesaver for these plants.
In the spring, be sure to remove the mulch to allow new growth at the soil surface. This will give your peonies the best chance to thrive and produce beautiful blooms.

Dividing Peonies
Peonies don't need regular division for successful blooming.
The best time to divide your mature peony plants is in the fall when the plant is nearing dormancy.
You can divide your peonies as a form of propagation to have more plants.
Peony roots cut into pieces with 3-5 eyes have the best chance of success.
By dividing your peonies in the fall, you'll be giving them the best chance to establish themselves before the next growing season.

Do Flowers Need Staking?

Some flowers, like peonies, need staking to support heavy blooms, especially in rainy climates.
Peonies with strong stems don't require staking, making them a great option for those who want to avoid the hassle.
Herbaceous peonies can be supported with a peony ring, while tree peonies do better with bamboo stakes and natural twine.
If you live in a rainy climate, staking your peonies can help showcase their beautiful blooms even better.
Growing in Pots
Growing peonies in pots requires some special care, but it's definitely doable.
Peonies need a large container with plenty of drainage holes to thrive. I've found that self-watering containers like Aquapots are a great option because they dry out quickly and don't require constant monitoring.
If you choose to use a self-watering container, you'll have more flexibility in your care routine.
