Euphorbia palustris (Marsh Spurge)

Euphorbia palustris, commonly known as Marsh Spurge, is a robust and versatile perennial valued for its bright green foliage and striking yellow-green flower bracts. Thriving in damp or waterlogged conditions, this low-maintenance plant is perfect for borders, bog gardens, and naturalized areas near ponds or streams.

Description

• Height: 80–120 cm (31–47 inches)
• Spread: 50–80 cm (20–31 inches)
• Flowers: From late spring to early summer (May to June), Euphorbia palustris produces clusters of chartreuse-yellow bracts that surround tiny, inconspicuous flowers. The vibrant bracts provide long-lasting color and contrast beautifully with surrounding plants.
• Foliage: The lance-shaped, mid-green leaves form a dense clump of upright stems. In autumn, the foliage turns golden-yellow, adding seasonal interest.
• Growth Habit: Upright and bushy, this plant adds both height and texture to the garden.

Growing Conditions

Euphorbia palustris thrives in moist to wet soils, making it ideal for water-rich environments and areas prone to occasional flooding.

• Soil: Prefers moist, fertile, well-drained soil but can tolerate heavier, clay-rich soils as long as they retain moisture.
• Water: Requires consistently moist soil, particularly during the growing season. It can grow in shallow standing water near ponds or streams.
• Light: Grows best in full sun to partial shade. In full sun, ensure the soil remains moist to prevent stress.

This perennial is hardy in temperate climates, including the UK, and tolerates frost well.

Propagation and Care

• Division: Propagate by dividing clumps in spring or early autumn. Replant divisions immediately in prepared, moist soil.
• Seed: Sow seeds in autumn or spring, as they require a period of cold stratification to germinate.
• Routine Care:
  • Water regularly to maintain soil moisture, especially during dry periods.
  • Cut back stems to ground level in late autumn or early spring to encourage fresh growth.
  • Wear gloves when handling, as the sap can be irritating to skin and eyes.
  • Mulch annually to retain soil moisture and suppress weeds.

Uses

1. Ornamental Planting: The bold bracts and upright growth habit make Euphorbia palustris an excellent choice for mixed borders, bog gardens, and naturalized landscapes.
2. Water Gardens: Thrives in damp areas, making it perfect for planting near ponds, streams, or rain gardens.
3. Wildlife Gardens: Its nectar-rich bracts attract pollinators, while the dense foliage offers shelter for insects and small creatures.
4. Cut Flowers: The vibrant bracts can be used in fresh or dried arrangements, though care should be taken to avoid sap contact.

Ecological Value

• Pollinators: The nectar-rich flowers and bracts attract bees, butterflies, and other pollinators during late spring and early summer.
• Wildlife Habitat: Provides shelter for insects and small animals, particularly in wetland or naturalized areas.
• Erosion Control: Its fibrous root system helps stabilize soil in damp or sloped areas, reducing erosion.

Considerations

• Toxicity: The milky sap is toxic if ingested and can cause skin irritation. Always wear gloves when handling and keep the plant away from pets and children.
• Moisture Needs: Requires consistently moist soil for optimal growth. Avoid planting in dry or well-drained areas.
• Spread: While not invasive, Euphorbia palustris can spread slowly via underground roots, so regular maintenance may be required in smaller gardens.
