How to grow

Sun Valley is a fast-growing tree, suitable for most situations, including areas of low rainfall. However for the best autumn colour it should be planted in full sun in a moisture-retentive soil. 


'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.
