Acer saccharinum, commonly known as silver maple, creek maple, silverleaf maple, soft maple, large maple, water maple, swamp maple, or white maple, is a species of maple native to the eastern and central United States and southeastern Canada. It is one of the most common trees in the United States. Although the silver maple's Latin name is similar, it should not be confused with Acer saccharum, the sugar maple. Some of the common names are also applied to other maples, especially Acer rubrum. The silver maple tree is a relatively fast-growing deciduous tree, commonly reaching a height of , exceptionally . Its spread will generally be wide. A 10-year-old sapling will stand about tall. It is often found along waterways and in wetlands, leading to the colloquial name "water maple". It is a highly adaptable tree, although it has higher sunlight requirements than other maple trees. The leaves are simple and palmately veined, long and broad, with deep angular notches between the five lobes. The long, slender stalks of the leaves mean that even a light breeze can produce a striking effect as the downy silver undersides of the leaves are exposed. The autumn color is less pronounced than in many maples, generally ending up a pale yellow, although some specimens can produce a more brilliant yellow and even orange and red colorations. The tree has a tendency to color and drop its leaves slightly earlier in autumn than other maples. The flowers are in dense clusters, produced before the leaves in early spring, with the seeds maturing in early summer. The fruit are samaras, each containing a single seed, and winged, in pairs, small ( in diameter), the wing about long. The fruit are the largest among the maples native to its range. Although the wings provide for some transport by air, the fruit are heavy and are also transported by water. Silver maple and its close cousin red maple are the only Acer species which produce their fruit crop in spring instead of fall. The seeds of both trees have no epigeal dormancy and will germinate immediately.
