Acer campestre – Field Maple

The Field Maple is known in America Hedge Maple tree, scientific name is Acer campestre, that may attain a height of 20 to 70 feet, but is most familiar as a mere bush of the wayside or hedgerow, particularly on chalk or lime-stone formations, when displaying its colorful winged fruits, it is a very pretty tree.

The slender twigs are light brown, and after the first year may have a layer of cork that project out wards in conspicuous irregular vertical ridges. The opposite winter buds are brown, with short hairs on the scales. The leaves as they unfold are often tinged with a rosy or pinky red, and have a leaf-stalk which is usually tinged with red or brown, they are small (rarely more than 2 inches in length or breadth) and have normally five rounded lobes. They are dull green above but paler green below, and turn to a bright golden shade in autumn.

The erect, few-flowered inflorescence comprises small pale greenish-yellow flower usually of both sexes, which open in May. Their two-lobed ovary develops into a double ‘samara’ – and almost straight pair of broad-winged ‘keys’ about 0.5 – 1 inch long. With their bases joined together. In summer these ‘keys’ are often tinged with crimson, afterwards turning brown as they ripen. 

The bark is light brown, sometimes with a dull orange tinge, smooth at first but be-coming darker and furrowed with small scales which flake of. The wood is pale brown, hard, tough and strong. When sufficiently large, it is ideal for carving or for turning into bowls and platters.
