Alnus cordata


Common Name(s):

  • Italian Alder
  • Alder
SKU: 67f1d9e0e79a Category:


A fast growing, conical/pyramidal-shaped, deciduous tree. Yellow catkins appear in late winter and early spring followed by heart-shaped glossy deep green leaves. Small cones appear and remain on the tree throughout autumn. Thrives on almost all types of ground including dry, but is most at home by the waterside and grows well in poor soil. Being tolerant of pollution, it is ideally suited to large urban gardens, but avoid planting next to hard surfaces as its vigour could result in lifting.
