Acer x freemanii ‘Armstrong’ has a more narrow, columnar canopy than the naturally occurring hybrid Acer x Fremanii. Originally spotted by Neil Armstrong, he bought the unusually upright tree for $5, thinking it would be of interest to his friend the famous horticulturist Edward Scanlon. Scanlon Nurseries propagated the form in the late 1940s and this cultivars unique benefits are still widely used within urban locations around the world today.

The tall, narrow tree canopy of A. Armstrong can reach 15-20 metres in height but retains a slim 3 metre width. It is ideal for urban locations and roadside planting where available space is at a minimum. Once mature, it may spread a little at its bottom forming a slight egg shape, but this is very simple to prune back and reform.

The summer leaves are emerald green, with a silver-blue underside. The trees autumn colour is a stunning ornamental feature, with deep butter-yellow hues flushed with shades of ruby candy apple. It is a female cultivar, so produces red winged seeds in the early spring.
