Acer rubrum Sun Valley

  • Height 10 years: 3m-5m / 10ft-16ft
  • Leaf colour - autumn: Orange / Red

A fine example of the Canadian Maple or Red Maple, with spectacular fiery red autumn colours.

The dull red flowers appear before the leaves in March.

The leaves are dark green, with a silvery-blue sheen on the undersurface. The stems of emerging leaves are often tinged red.

'Sun Valley' is related to Acer rubrum 'Somerset' and is a cross of Acer rubrum 'Red Sunset' and Acer rubrum 'Autumn Flame' and was introduced by the US National Arboretum. All these cultivated varieties are more reliable in producing autumn colours in UK conditions than the original Acer rubrum.

Acer rubrum is clearly related to Acer saccharinum (the silver maple), but is not quite as fast-growing.
