In landscaping, an avenue, alameda, or allée, is traditionally a straight path or road with a line of trees or large shrubs running along each side, which is used, as its Latin source venire indicates, to emphasize the "coming to," or 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.

A boulevard is a type of broad avenue planted with rows of trees, or in parts of North America, any urban highway or wide road in a commercial district.
