Types of Peonies

There are three main types of peonies:

1. Herbaceous Peonies

Herbaceous peonies are the most common and widely grown type. They have soft stems that die back to the ground during winter and re-emerge in the spring.

Herbaceous peonies offer a wide range of flower forms and colors, making them a popular choice for garden borders and cut flower arrangements.

2. Tree Peonies

Tree peonies, also known as woody peonies, are deciduous shrubs that produce large, woody stems. Unlike herbaceous peonies, tree peonies do not die back in winter and provide year-round structure to the garden. These peonies often have larger flowers and a longer blooming period.

3. Intersectional Peonies

Peonies that combine herbaceous and tree varieties are known as intersectional peonies or Itoh peonies. They offer the best of both worlds, combining the sturdy stems of tree peonies with the wide range of colors and flower forms found in herbaceous peonies. Intersectional peonies are known for their disease resistance and extended blooming period.

Benefits of Growing Peonies from Seeds

While growing peonies from seeds requires patience and time, there are several benefits to this method:

• Cost-effectiveness: Growing peonies from seeds is more affordable compared to purchasing established plants or roots.
• Wider variety of options: By starting from seeds, you have access to a broader selection of peony varieties, allowing you to experiment with different colors, flower forms, and fragrance profiles.
• Enjoying the process: Growing peonies from seeds is a rewarding experience that allows you to witness the entire life cycle of the plant, from seed to bloom. It can be a fulfilling journey for gardening enthusiasts and those seeking a deeper connection with their plants.

In the following sections, we will guide you through the process of growing peonies from seeds, ensuring that you have all the information and tools necessary for success.

Gathering Peony Seeds

To begin growing peonies from seeds, you’ll need to collect ripe seeds. Here’s how to do it:

When and where to collect seeds: Peony seeds are typically ready for harvest in late summer or early fall when the seed pods start to turn brown and crack open. Choose a dry day to collect the seeds.

Identifying ripe seeds: Ripe peony seeds are usually dark brown or black, firm, and have a hard outer shell. Avoid collecting immature or shriveled seeds.

Extracting seeds from peony pods: Gently open the cracked seed pods and remove the seeds. You can use your fingers or a small knife to carefully extract the seeds. Place the seeds in a clean container or envelope for further preparation.

Preparing the Seeds for Planting

Before planting the peony seeds, they need to go through a preparation process called stratification. This helps mimic the natural winter conditions that peony seeds require for successful germination. Here’s how to prepare the seeds:

1. Cleaning and drying the seeds: Remove any remaining debris or pulp from the seeds by rinsing them gently in water. Use a paper towel to gently pat them dry or let them air dry.
2. Stratifying the seeds: Peony seeds need a cold period to break their dormancy. Place the cleaned seeds in a damp paper towel or a plastic bag filled with moistened peat moss or vermiculite. Seal the bag or wrap the towel around the seeds, and then refrigerate them for 8 to 12 weeks. Check the moisture levels periodically and ensure they remain slightly damp.
3. Soaking the seeds: After stratification, you can enhance germination rates by soaking the seeds in room temperature water for 24 to 48 hours. This softens the hard seed coat and helps trigger germination.

Germinating Peonies Seeds

Once the stratification and soaking process is complete, it’s time to germinate the peony seeds. There are a few methods you can use:

• Using the baggie method: Moisten a paper towel and place the seeds on one half of the towel. Fold the towel over to cover the seeds and place it inside a resealable plastic bag. Leave a portion of the bag open to let air in. Keep the bag in a warm location with indirect light, and check the moisture levels regularly to prevent drying out. Within two to three weeks, germination ought should happen.
• Preparing a seed tray: Fill a seed tray or small pots with a well-draining seed-starting mix. Plant the peony seeds about 1 inch apart and cover them with a thin layer of soil. Water the seeds gently to moisten the soil. Place the tray or pots in a warm area with indirect light. Maintain consistent moisture levels in the soil by misting or light watering. It typically takes 3 to 4 weeks for germination.

• Optimal conditions for germination: Peony seeds require temperatures between 60°F and 70°F (15°C to 21°C) for successful germination. Ensure they receive sufficient indirect light, but avoid exposing them to direct sunlight, as it may cause excessive heat buildup.

Transplanting Peonies Seedlings

Once the peony seedlings have germinated and developed a few sets of true leaves, they can be transplanted into individual containers or the garden. Follow these steps for successful transplantation:

• Selecting the right container or garden spot: Choose containers with drainage holes or prepare a garden spot with well-draining soil. Peonies prefer a location with full sun to partial shade.
• Preparing the soil: If transplanting into containers, use a high-quality potting mix. For garden planting, amend the soil with organic matter such as compost to improve drainage and fertility.
• Planting the seedlings: Dig a hole or create a small depression in the soil that is large enough to accommodate the seedling’s root system.

Gently remove the seedling from its current container or seed tray, taking care not to damage the delicate roots. Place the seedling in the hole or depression and backfill with soil, ensuring the crown of the seedling sits at ground level. Lightly firm the soil around the base of the seedling.
