Traditionally, an avenue is a straight road with a line of trees or large shrubs running along each side, which is used, as its French source venir "to arrive" indicates, to emphasize the arrival at a landscape or architectural feature. In most cases, the trees planted in an avenue will be all of the same species or cultivar, so as to give uniform appearance along the full length of the avenue. The French term, allée, is confined normally to avenues planted in parks and landscape gardens.
