Selected by Newton Armstrong in the States in 1947
This small to medium tree has a tightly columnar habit, making it very useful as a street and car park tree
It is half Acer rubrum and half Acer saccharinum but the later dominates with autumn colour of orange and yellows rather than glorious scarlet.
The toughness of its Silver Maple parentage makes it a better bet than Acer rubrum and its cultivars when manganese is not present in the soil.
It tolerates urban conditions but as a warning note is very susceptible to damage by glyphosate (Roundup) so beware.
Mature height: 10-15m
