This cultivar originated in the USA in 1951 and until recently was considered to belong to A. rubrum. Recent studies reveal that 'Armstrong' came into being from a crossing between A. rubrum and A. saccharinum and therefore belongs to the hybrid Acer x freemanii. This hybrid was not only created by man, for it also grows in the wild in the USA. The green leaves have 3 to 5 lobes. Their under surface is grey-green. In our country the beautiful orange-red autumn colour can only be seen after a hot summer. It roots widely with a dense branching. 'Armstrong' requires a not too limy soil. The tree can be used well in hard surfaces, which renders it very suitable to be used in narrow streets and avenues.
