Thuja plicata 'Whipcord'
  • RHS AGM

western red cedar 'Whipcord'

A compact, slow-growing conifer forming a flattened mound when young but gradually acquiring a more rounded shape, ultimately reaching a height and spread of 1.5m. The pendulous, whipcord-like branches bear small, scale-like, glossy green leaves pressed against the stems; these leaves often develop bronze shading in winter
