Royal Wedding Poppy Care Guide

The Royal Wedding Poppy (Papaver somniferum ‘Royal Wedding’) is a stunning and delicate variety of the popular poppy flower. Known for its unique and dramatic white blooms with contrasting dark centers, this variety is often a standout in any garden. It’s ideal for gardeners looking for a striking addition to flower beds or containers. Despite its elegance, the Royal Wedding Poppy is a relatively easy plant to care for, making it suitable for both novice and experienced gardeners alike.

In this guide, we’ll go through all the essential aspects of planting, growing, and caring for Papaver somniferum ‘Royal Wedding’ poppies to help you get the most out of these beautiful blooms.

1. Overview of Royal Wedding Poppy

The Royal Wedding Poppy is a cultivar of the Papaver somniferum, commonly known as the opium poppy, but it’s cultivated specifically for ornamental purposes. It has large, bowl-shaped flowers that are a creamy white color with dark purple to black centers. These flowers typically measure between 4-6 inches in diameter, creating a stunning contrast in the garden.

Height: Royal Wedding poppies grow tall, reaching between 24-36 inches (60-90 cm) in height.
Flower Color: White with a contrasting dark center (usually purple or black).
Flowering Season: Typically blooms in late spring to early summer.
Hardiness Zone: Grows well in USDA zones 3-9.
Plant Type: Annual (though it may self-seed in some areas, allowing for growth in subsequent seasons).

2. Choosing the Right Location

Royal Wedding poppies, like most poppies, require specific growing conditions to thrive and produce their impressive blooms. Here’s how to choose the right location for planting them:

Sunlight: Poppies love full sun, so choose a location that receives at least 6-8 hours of direct sunlight per day. The sunlight helps them produce strong stems and vibrant flowers.
Soil: These poppies thrive in well-draining, slightly alkaline soil. They are relatively tolerant of poorer soil, but for the best results, the soil should be loamy and rich in organic matter. If your soil is acidic, you can amend it with lime to increase the pH slightly.
Spacing: Plant the poppies about 12-18 inches apart to give them room to grow tall and spread. The space ensures proper air circulation and reduces the risk of fungal diseases.

3. Planting Royal Wedding Poppy

Planting Royal Wedding Poppies is relatively straightforward. These poppies are typically grown from seed, which you can sow directly into your garden or start indoors and transplant later.

Best Time to Plant: Poppies can be planted in early spring as soon as the soil can be worked, or in late fall. In most regions, it’s best to plant in early spring after the danger of frost has passed, as they require a cool period to germinate.
Planting Seeds Directly Outdoors:
- Prepare the soil by loosening it with a garden fork or tiller to a depth of about 2-3 inches.
- Scatter the seeds lightly over the soil surface, as poppies need light to germinate. You can gently press them into the soil by raking the area lightly or pressing with a board.
- Water the area gently, making sure the soil stays moist but not waterlogged.
Starting Seeds Indoors: If you want an earlier bloom, you can start seeds indoors 6-8 weeks before your last expected frost. Use seed trays or small pots with well-draining seed-starting mix. Place the seeds on the surface and lightly press them into the soil. Keep the trays in a cool area, around 55-60°F (13-16°C), to encourage germination. After the seedlings have developed a few sets of leaves and the outdoor conditions are favorable, transplant them into the garden.

4. Watering Royal Wedding Poppy

Poppies are relatively drought-tolerant once established but do require consistent moisture during germination and early growth. Here’s how to water them properly:

During Germination: Keep the soil consistently moist but not soggy during the germination phase. Poppy seeds will germinate in 7-14 days under ideal conditions.
Established Plants: Once the plants have grown, water them deeply but infrequently. It’s important to allow the soil to dry out between waterings. Over-watering can lead to root rot or fungal diseases.
Avoid Wetting the Leaves: Water the soil at the base of the plants, avoiding wetting the foliage. This reduces the risk of fungal issues, especially during rainy weather.

5. Feeding and Fertilizing

Poppies are not heavy feeders, but providing some nutrients can encourage healthier growth and more abundant blooms.

Fertilizing Schedule: Apply a balanced, slow-release fertilizer at the time of planting to give the plants a boost. You can also fertilize lightly with a diluted liquid fertilizer during the growing season (about once a month) if your soil is poor.
Organic Options: If you prefer organic gardening, compost or well-aged manure is an excellent choice. Apply a thin layer of compost around the base of the plants during early spring, which will enrich the soil and provide steady nutrients throughout the growing season.

6. Pruning and Deadheading

Pruning: Royal Wedding Poppies do not require much pruning. However, if the stems become tall and leggy, you can trim them back slightly to encourage bushier growth.
Deadheading: For the most part, poppies will self-seed, meaning that you don’t have to worry much about deadheading, but removing spent flowers can help to keep the plant looking neat. If you don’t mind letting the flowers go to seed, this variety will often produce seedlings that grow into new plants in the following season.

7. Common Pests and Diseases

Royal Wedding Poppies are relatively pest-resistant, but they can be affected by a few common garden pests and diseases:

Aphids: These small, green insects can feed on the sap of the plant, potentially causing distortion of the leaves and stems. If you notice aphids, you can wash the plants off with a strong stream of water or apply insecticidal soap.
Slugs and Snails: These pests are attracted to tender leaves and stems. Set up traps or apply diatomaceous earth around the base of the plants to deter slugs and snails.
Powdery Mildew: In humid or wet conditions, poppies can be susceptible to powdery mildew, a fungal disease. To prevent this, ensure proper spacing between plants to allow for good air circulation and avoid overhead watering. If powdery mildew appears, remove affected leaves and treat the plant with fungicide if necessary.
Root Rot: This can occur if the soil is not well-draining or if the plants are overwatered. Make sure the soil drains well, and avoid watering too frequently.

8. Overwintering and Winter Care

In most climates, Papaver somniferum ‘Royal Wedding’ is grown as an annual. However, if you live in a region with mild winters, you might be able to enjoy these poppies as a biennial or even allow them to self-seed and grow in the next year.

Protecting Self-Seeding: If you want your poppies to come back next season, allow the flowers to go to seed. After the seed pods mature, collect the seeds and store them in a cool, dry place until the following spring. Alternatively, let them fall to the ground where they will self-sow.
Mulching for Winter: If you want to protect the plant for next year (in milder climates), lightly mulch around the base to protect the seeds or roots from frost.

9. Propagating Royal Wedding Poppy

Royal Wedding Poppies can be propagated from seed, either sown directly in the garden or started indoors. As mentioned earlier, they will often self-seed, so you may find new plants sprouting in the same spot next season.

10. Conclusion

The Royal Wedding Poppy is a spectacular addition to any garden, offering dramatic, eye-catching flowers with minimal care. By following the proper planting, watering, and maintenance guidelines, you can enjoy these beautiful blooms year after year. Whether grown in flower beds, containers, or as part of a larger ornamental garden, these poppies will bring a touch of elegance and grace to your outdoor space. With their resilience and ability to self-seed, they can provide a long-lasting display, making them a favorite for many gardeners.
