Maple

Acers, the maple trees, are among the most easily-identified of the great trees. Most lay persons recognize the shape of their leaves, although some other genuses have similar-shaped leaves as well, and it is really the fruit, or samaras, that distinguish the genus. There are over one hundred species with variable habits. The maple is Canada’s national tree. Another well-known species is the sugar maple, Acer saccarum that produces maple syrup.

Among the most popular ornamental species is Acer negundo, known as "box elder" the US and "Manitoba maple" elsewhere, prized for its compound leaves and variegated culivars. Acer palmatum (called the “Japanese Maple” although Acer japonica and Acer nipponicum exist as well), is probably the most popular specimen tree for house parks and home gardens, due in no small part to the delicate foliage and spectacular autumn colours of many. Selective breeding has produced hundreds of varieties. In the right climates (cool temperate) Japanese Maples are generally hardy and drought-resistant, although the leaves of some of the most beautiful varieties will burn in scorching sun.

Commercial uses

Specially bred and decorative species are often used in landscaping, but Maples also serve many commercial uses. Maple wood is preferred by many craftsman and furniture makers for its strength and resistance to wear as well as its character and grain patterns. "Bird's eye" and "fiddleback" figures are especially prized. Maple is also used extensively for flooring, benchtops and cutting boards. The production of maple syrup and maple candy, made from the sap of sugar maples (Acer saccarum), also represents a significant industry, especially in Canada and the northeastern part of the United States. In recent years, in the face of global warming, the syrup industry is being disrupted by increasingly smaller annual yields because of shorter harvesting seasons at the end of winter.

Maples are also popular subjects for bonsai.
