Purging Buckthorn (rhamnus cathartica)

• Native UK species, commonly found in scrub, woodland, and hedgerows, especially on chalky soils in England and southern Wales.
• Highly valuable for wildlife: sole larval foodplant (along with Alder Buckthorn) for Brimstone butterfly caterpillars; supports Tiger Moth larvae; flowers attract adult butterflies and bees; black berries provide autumn food for birds.
• Forms dense, thorny thickets ideal for secure hedging, wildlife habitats, or informal barriers up to 6-8m tall.
• Attractive glossy dark green leaves turning yellow in autumn; produces small yellowish-green flowers and red-to-black berries.

Planting Guide

• Site selection: Tolerates full sun, partial shade, or full shade; prefers moist but well-drained soil; thrives on chalky/calcareous soils but adapts to most types, including poor or coastal conditions.
• Hardiness: Fully hardy across the UK.
• Planting time: Best in dormant season (November-March) using bare-root plants.
• Spacing: For hedging, plant 30-45cm apart in a single row or staggered double row.
• Care: Water well in first year; minimal pruning needed (summer if required); can be coppiced for regrowth.
• Caution: Berries and leaves mildly toxic to humans/pets (laxative effect); consider wearing gloves when handling; plant is dioecious (needs male and female for berries).
