Peonies are a spring flower, known for their beautiful hues of pinks, reds, whites and yellows. Peonies symbolize romance, prosperity and good fortune, making them popular wedding flowers. These stunning flowers can bloom for 100 years if planted properly and cared for.
Not only do peonies look beautiful in a garden, but they add an elegant and feminine touch as cut flowers in your house as well. To help you grow healthy and full blooms in your yard, we’re sharing a peony care guide that includes types of peonies, how to plant them and how to care for them.
Peonies are perennial flowers that come in three main varieties: herbaceous (bush), tree and Itoh (intersectional).
The peony bush, or herbaceous peonies, are low maintenance plants that can thrive in the same spot for more than 50 years. They require little water and naturally resist most pests. Some popular varieties include the Paeonia officinalis and the Paeonia lactiflora.
The tree peony or paeonia suffruticosa blooms in April and May and is native to China. The stems of the peony tree stay above the ground all year and it produces much larger flowers than the other varieties. They reach up to 10 inches in diameter.
Intersectional peonies are a cross between the herbaceous peony and the tree peony. This hybrid blooms later in June. It’s commonly found as a border in gardens due to it’s attractive bloom and lower height than the other varieties.
Peonies are a low-maintenance flower that are a beautiful addition to any garden. If planted in the right conditions, they should bloom within a few years of being planted.
Hey there, fellow garden enthusiasts! I’ve been growing peonies for years at Stone Post Gardens, and one question keeps popping up: “Do peonies need a lot of sunlight?” Let me break it down for you in simple terms – these gorgeous bloomers definitely love their sunshine, but there’s more to the story than just sticking them in full sun and hoping for the best.
The Quick Answer
Most peonies need at least 6 hours of direct sunlight daily to produce those stunning blooms we all love. But don’t worry if your garden isn’t a sun-soaked paradise – some varieties can handle partial shade pretty well.
Different Types of Peonies and Their Sun Requirements
Herbaceous Peonies
- Need full sun (6+ hours daily)
- Best flowering in all-day sun
- Avoid spots with less than 4 hours of sun
Tree Peonies
- More shade-tolerant than other types
- Need about 6 hours of sun
- Can handle partial shade better than herbaceous varieties
Intersectional (Itoh) Peonies
- Require full sun for best blooms
- Minimum 6 hours direct sunlight
- Amazing dinner-plate sized flowers when given proper light
Perfect Spots to Plant Your Peonies
When I’m helping customers choose spots for their peonies, I always recommend these locations:
- Southern exposure
- Eastern exposure

Pro Tips for Placement:
- Check sunlight patterns throughout different seasons
- Place at border edges or mid-border for maximum sun exposure
- Keep away from tall plants that might shade them
- Consider afternoon shade in super hot climates
What Happens When Peonies Don’t Get Enough Sun?
Trust me I’ve seen what happens when these beauties don’t get enough light and it ain’t pretty

Look, I know not everyone’s got that perfect sunny spot. Here’s what I tell my customers about growing peonies in partial shade:

Care Tips for Sun-Loving Peonies
Planting Depth Matters!
One of the biggest mistakes I see is planting too deep. Keep those tuberous roots just 2.5cm below the surface. If they’re deeper, you’ll get lovely leaves but no flowers – what a bummer!
Soil Requirements
- Well-draining soil is crucial
- Does fine in clay or chalky soil
- Just keep it from getting waterlogged
- Add organic matter if soil’s poor
Maintenance Tips
- Cut back dead leaves in fall
- Light fertilizer in spring if needed
- Keep area around plants clear
- Monitor for disease in shadier spots

Q: Why are my peonies not blooming?

The Bottom Line
While peonies definitely prefer their daily dose of sunshine, don’t let less-than-perfect conditions stop you from growing these beauties. With the right variety selection and proper care, you can still enjoy gorgeous blooms even in partially shaded gardens.
Remember, gardening’s all about working with what you’ve got. I’ve seen stunning peonies growing in all sorts of conditions – it’s just about understanding their needs and making smart choices about placement and care.

When to Plant Peonies
Peonies should be planted in the fall, ideally from late September to October. In warmer areas of the South, they should be planted even later. If peonies are planted in spring, they may not bloom for the first few years. Planting them about six weeks before the first frost will allow them to settle and survive the colder temperatures of winter.
A common question that arises when planting peonies is, “Do Peonies need full sun or shade?” Peonies should be planted in an area that receives full sun. They should receive five to six hours of full sunlight per day. On the other hand, too much sunlight can also be harmful, so ensure they are planted in an area that gets some afternoon shade.
While peonies are growing, it’s recommended that they receive an inch of water each week. Be sure the soil doesn’t get too much water and become waterlogged.
Peonies should be planted in soil that drains well and is rich in organic matter. The soil pH should be neutral. If the soil is lacking nutrients, add a slow-release organic fertilizer.
To plant peonies in your garden, find a location that has good air circulation and gets full sun. They should be protected by strong winds and be planted away from other trees and shrubs so they don’t have to compete for food and water.
