Papyrus (Cyperus papyrus) can be grown in the UK, but since it’s a plant native to warmer, tropical regions like Egypt and parts of Africa, it requires specific care to thrive. In the UK’s cooler climate, papyrus is usually grown as a pond or bog plant, often in containers or pots, and may need to be brought indoors during winter or grown in a greenhouse.

Growing Papyrus in the UK

Here’s what papyrus generally requires:

1. Location: Full sun to partial shade. It thrives best in warm and bright conditions.
2. Water: Papyrus is a marsh plant, so it needs constant moisture. Plant it in shallow water, the edge of a pond, or in very water-retentive soil.
3. Temperature: Papyrus is not frost-hardy. During winter, temperatures must not drop below 5°C (41°F). It should be brought indoors or protected in a greenhouse.
4. Soil: It prefers rich, loamy soil with good water retention. Ensure the soil is consistently wet, almost bog-like.
5. Containers: If you’re growing papyrus in a pot, ensure that the container is large enough to accommodate the root system and keep it in a water tray to mimic the marshy environment.
6. Overwintering: In colder months, move your papyrus into a greenhouse or indoors where the temperature stays above freezing. It can be cut back in winter when growth slows down.

Best Varieties of Papyrus to Grow in the UK

1. Cyperus papyrus (Common Papyrus)

• Description: The traditional papyrus plant that was historically used by the Egyptians for paper-making. It has tall, green, triangular stems that can grow up to 2-3 meters in ideal conditions, with umbrella-like clusters of fine, thread-like leaves on top.
• Growing Requirements: Needs lots of water, full sun, and protection from frost. Ideally grown near a pond or in a container filled with water.

1. Cyperus alternifolius (Umbrella Plant)

• Description: Often referred to as the umbrella papyrus, this species is smaller than Cyperus papyrus, reaching about 1-1.5 meters. It has a similar look, with radiating leaves that resemble an umbrella, but it’s easier to manage in smaller spaces.
• Growing Requirements: Easier to grow indoors, in water or very wet soil. It can also tolerate partial shade and is better suited for container planting.

1. Cyperus involucratus (Dwarf Papyrus)

• Description: A compact variety, reaching about 60-90 cm (2-3 feet) in height. It has similar umbrella-like foliage but is smaller and more manageable in smaller gardens or ponds.
• Growing Requirements: It prefers full sun and constant moisture, though it can be grown indoors in containers or in water gardens. It also needs to be protected from frost.

General Care Tips:

• Fertilizing: Papyrus grows rapidly in fertile conditions. A liquid fertilizer high in nitrogen can help boost its growth in summer.
• Pruning: Trim any brown or yellowing leaves, especially before bringing the plant indoors for winter.
• Pest Control: Aphids and spider mites can occasionally attack papyrus, especially indoors. Regular misting can help keep pests away, or use a gentle insecticidal soap if necessary.

In conclusion, with proper care, papyrus can be a stunning addition to a UK garden, especially in pond areas or as a striking potted plant. However, it’s crucial to manage its water needs and protect it from frost during the colder months.
