1. History and Origin
- Native Habitat: Peonies are native to Asia, Europe, and Western North America.
- Cultural Significance: In China, peonies are known as the "King of Flowers" and symbolize wealth, honor, and prosperity. They have been cultivated for over 2,000 years.
- Introduction to the West: Peonies were introduced to Europe in the 18th century and quickly became popular in gardens and floral arrangements.

2. Botanical Characteristics
- Family: Paeoniaceae.
- Genus: Paeonia.
- Plant Type: Herbaceous perennials and woody shrubs (tree peonies).
- Height: Ranges from 2 to 4 feet for herbaceous peonies and up to 7 feet for tree peonies.
- Flower Size: Blooms can be as small as 2 inches or as large as 10 inches in diameter.
- Flower Forms: Single, semi-double, double, and bomb types.

3. Popular Peony Varieties
- Herbaceous Peonies: Die back to the ground in winter and regrow in spring (e.g., ‘Sarah Bernhardt’, ‘Festiva Maxima’).
- Tree Peonies: Woody shrubs that retain their structure year-round (e.g., ‘High Noon’, ‘Kamata-nishiki’).
- Itoh Peonies: Hybrids between herbaceous and tree peonies, known for their large blooms and strong stems (e.g., ‘Bartzella’, ‘Cora Louise’).

4. Cultivation Tips
- Soil: Peonies thrive in well-draining, fertile soil with a pH of 6.5–7.0.
- Sunlight: Full sun (at least 6 hours daily) is ideal, though they can tolerate partial shade.
- Watering: Keep the soil consistently moist but not waterlogged. Mulching helps retain moisture.
- Fertilization: Use a balanced fertilizer (e.g., 10-10-10) in early spring and after blooming.
- Planting: Plant bare-root peonies in the fall, ensuring the eyes (growth points) are no more than 2 inches below the soil surface.
- Spacing: Space plants 3–4 feet apart to allow for air circulation and growth.
---
5. Propagation
- Division: The most common method for herbaceous peonies. Divide mature plants in the fall, ensuring each division has at least 3–5 eyes.
- Seeds: Peonies can be grown from seeds, though this method is slow and often used for breeding new varieties.
- Cuttings: Tree peonies can be propagated from semi-hardwood cuttings taken in late summer.

6. Pests and Diseases
- Common Pests: Ants are often seen on peonies but are harmless and help protect the flowers from other pests. Aphids and thrips can occasionally be problematic.
- Diseases: Botrytis blight, powdery mildew, and root rot can affect peonies. Ensure good air circulation and avoid overhead watering to prevent these issues.
- Prevention: Regularly inspect plants and remove any diseased or infested foliage.

7. Floral Design Applications
- Bouquets: Peonies are a favorite for wedding bouquets and floral arrangements due to their large, fragrant blooms.
- Centerpieces: Their lush flowers make them ideal for table centerpieces and event decor.
- Seasonal Displays: Peonies are perfect for spring and early summer arrangements, pairing beautifully with roses, lilacs, and hydrangeas.
- Color Palette: Peonies come in shades of white, pink, red, yellow, and coral, making them versatile for any design theme.

8. Botanical Research and Breeding
- Genetic Diversity: Peonies are a model organism for studying flower development and pigmentation due to their wide range of colors and forms.
- Hybridization: Breeders continue to develop new varieties with unique traits, such as improved disease resistance, longer vase life, and novel colors.
- Conservation: Efforts are underway to preserve wild peony species and their genetic diversity.
---
9. Cultural Significance
- National Flower: The peony is the national flower of China, symbolizing prosperity and honor.
- Art and Literature: Peonies have inspired artists, poets, and gardeners for centuries, often representing romance and compassion.
- Festivals: Peony festivals are held worldwide, celebrating the flower’s beauty and cultural importance.

10. Tips for Florists
- Harvesting: Cut peonies in the morning when they are in the "marshmallow" stage (soft buds showing color). Use sharp, clean shears to avoid damaging the stems.
- Conditioning: Place stems in warm water immediately after cutting to prolong vase life. Remove lower leaves to prevent bacterial growth.
- Arranging: Combine peonies with complementary flowers like roses, eucalyptus, and asters for stunning arrangements.
---
11. Tips for Botanists
- Field Studies: Explore the native habitats of wild peony species in Asia, Europe, and North America to study their ecology and evolution.
- Laboratory Research: Investigate the genetic and biochemical mechanisms behind peony pigmentation and flower development.
- Conservation Efforts: Collaborate with botanical gardens and seed banks to preserve rare and endangered peony species.
