Alders

Species

  • Grey Alder - Alnus incana
  • Green Alder - Alnus viridis
  • Italian Alder - Alnus cordata
  • Red Alder - Alnus rubra

Recommendations

Non-native Alders are occasionally planted on difficult and reclaimed sites as they are tolerant of very poor conditions. They are not recommended for planting in rural situations where the native Common Alder - itself a broadly tolerant species - is a more characteristic species.
