“Acer freemanii Autumn Blaze is a cultivar of a naturally occurring hybrid of Acer rubrum and Acer saccharinum, named after Oliver Freeman, who made the crossing at the US National Arboretum in the 1930s. Acer freemanii Autumn Blaze is a vigorous, oval headed, large tree which has dark green, deeply indented leaves, which turn a rich flame red in Autumn. Acer rubrum is often specified for this effect but very rarely does well on UK soils as it is dependent on the trace element manganese which it can only access at low ph. It possesses the prettiness of rubrum but the toughness of saccharinum so it is a much safer bet.”
