Acer platanoides Norway Maple I
This introduction is used extensively in parks and gardens so escapes occasionally into our waste areas and woodland. It looks at first glance like Acer pseudoplatanus (Sycamore) and can grow very tall like that tree. Closer observation reveals that the leaves are more pointed and the flowers which appear before the leaves are upright like Acer campestre (Field Maple) not pendulous like Acer pseudoplantanus.
Acer platanoides is found throughout England, most of Wales and Scotland but is less common in Ireland.
